| 15:51.07 | prpplague | T0mW: yep |
| 15:51.10 | prpplague | T0mW: what up? |
| 15:51.16 | chouimat|work | hi prpplague T0mW |
| 15:52.08 | T0mW | prpplague: so, let me get this straight. Even though the s3c2410 has a hardware spi master in the chip, we still must use the bitbang via spi_s3c24xx_gpio mechanism? |
| 15:52.33 | prpplague | T0mW: depends on what you are refering to |
| 15:53.14 | T0mW | prpplague: well, when I read the driver code (drivers/spi), I only see bitbang getting referred to for the s3c24xx processors. |
| 15:53.24 | prpplague | one sec |
| 15:53.35 | prpplague | phone |
| 15:53.37 | T0mW | k |
| 15:54.39 | T0mW | chouimat|work: good, almost, afternoon. heh |
| 15:54.47 | chouimat|work | T0mW: hi |
| 15:54.57 | chouimat|work | says something extremely offensive about javascript |
| 15:55.03 | T0mW | this spi stuff has really got me bugged |
| 15:56.23 | SpeedEvil | chouimat|away: what - 'Javascript is fast and stable, and an ideal platform for application development'? |
| 15:56.41 | prpplague | T0mW: the spi subsystem is in a total state of disarray |
| 15:56.52 | T0mW | prpplague: I totally agree with you |
| 15:56.57 | prpplague | T0mW: the s3c24xx spi driver does use the internal controller |
| 15:57.14 | T0mW | prpplague: I've been tracing the stupid thing via jtag and it is screwed up. |
| 15:57.19 | prpplague | T0mW: but the way the structure of the spi system works, it considers everything to be bit banged |
| 15:57.25 | T0mW | ok |
| 15:57.26 | prpplague | T0mW: for example |
| 15:58.16 | chouimat|work | SpeedEvil: ha ha ha ha |
| 15:59.02 | prpplague | T0mW: the encj2860 driver -> spi subsystem -> bitbang_spi -> s3c2410 spi controller |
| 15:59.02 | T0mW | prpplague: that much I've figured out that the spi_board_info->platform_data has to point to an spi gpio device description. That you have to specify the miso,mosi,sclk pinning, plus HZ, etc. |
| 16:00.01 | prpplague | T0mW: if you turn on the spi controller in the structure, to simply passes commands to it instead of bitbanging the gpios |
| 16:00.05 | T0mW | prpplague: are you sure it has to be chained that way? hardware_device -> spi_system -> bitbang_gpio_desc -> spi_bus_num ? |
| 16:00.39 | prpplague | T0mW: yea, totally non-intuitive |
| 16:01.13 | T0mW | prpplague: so, if you enable the platform_device for s3c_device_spi, that is a user-space acess (via /dev) only to the spi subsystem. it has no affect on the connection to the enc28j60 per se. |
| 16:01.32 | T0mW | you have to describe from the enc28j60 back to the spi bus? |
| 16:01.42 | T0mW | essentially |
| 16:01.47 | prpplague | one sec phone |
| 16:02.29 | T0mW | I've been going "forwards" from implementing the spi bus to attempting to attach the enc28j60 device onto that bus. |
| 16:03.27 | T0mW | sigh, that would prolly explain why register_driver keeps kicking the spi master out as it has nothing in "master->num_chipselects". |
| 16:05.21 | prpplague | T0mW: ok, lets just look at the spi section first |
| 16:06.30 | prpplague | T0mW: as i understand it, in your mach setup, you configure you spi bus, either as gpio's or as a spi controler, either way, the s3c24xx gpio driver is used |
| 16:06.46 | T0mW | correct |
| 16:07.17 | prpplague | T0mW: the gpio driver basically does some function calls for read/writes, if the spi controller is defined, it simply uses the function calls for it, instead of bit banging |
| 16:07.19 | prpplague | T0mW: now |
| 16:07.26 | prpplague | T0mW: to use the enc28j60 driver |
| 16:07.42 | T0mW | spi_board_info, right? |
| 16:07.51 | prpplague | T0mW: correct |
| 16:07.54 | T0mW | spi_board_info, right? for enc28j60 desc |
| 16:08.35 | prpplague | T0mW: correct, you will need to associate the enc28j60 driver with the spi device |
| 16:08.36 | T0mW | I'm thinking that the the spi_info struct is bullshit (num_cs, pin_cs) and should be ignored. |
| 16:08.56 | prpplague | T0mW: no you still need those |
| 16:09.20 | prpplague | T0mW: you'll need to tell it the number of ChipSelects for the SPI bus |
| 16:09.20 | T0mW | that the gpio description struct needs to go into s3c_device_spi0.dev.platform_data |
| 16:09.50 | prpplague | T0mW: there are several ways that you can do it, but any way you do it, it is a mess, imho |
| 16:09.52 | T0mW | ok, but that doesn't give me a /sys/class/spi_master |
| 16:10.29 | prpplague | T0mW: how quickly do you need the info for the enc28j60 stuff? |
| 16:10.36 | prpplague | T0mW: is this for the hammer? |
| 16:10.49 | T0mW | master->num_chipselects ALWAYS is 0 and register_bus ALWAYS dumps the attempt to create an spi bus master. |
| 16:11.16 | T0mW | regardless of what I do, I cannot set any chipselects, heh. |
| 16:11.28 | prpplague | that is odd indeed |
| 16:11.33 | T0mW | yes yes |
| 16:11.35 | T0mW | heh |
| 16:11.37 | prpplague | i'm swampped at the momment on the pda bringup |
| 16:11.47 | prpplague | but i can see if i have time tomorrow to tinker with the spi stuff |
| 16:11.55 | prpplague | i have an spi device that needs to be tested |
| 16:11.57 | T0mW | prpplague: np I just needed someone else to confirm that spi is whacked. |
| 16:12.05 | prpplague | indeed it is |
| 16:12.11 | T0mW | prpplague: then I can stop using a logical approach on it. |
| 16:12.17 | prpplague | and so poorly documented, i'm surprised anyone can use it |
| 16:13.11 | T0mW | YES docs really suck. They only tell you what a microcontroller person familiar with spi operation what spi is. Nothing about "real world" examples of linux driver implementation. |

| 21:49.41 | *** join/#edev RobotGuy (n=root@dsl093-038-072.pdx1.dsl.speakeasy.net) |
| 21:49.52 | T0mW | prpplague: however, the spi clock does not run, it stays high with no activity. |
| 21:50.32 | prpplague | hmm |
| 21:51.02 | prpplague | T0mW: does the pins for the spi controller get configured for spi operations? |
| 21:51.04 | T0mW | prpplague: if I use the spi_s324xx_gpio platform_device, it complains of "spi_s3c24xx_gpio: probe of spi_s3c24xx_gpio.0 failed with error -22" |
| 21:52.30 | T0mW | prpplague: I tried reading the map.h and tried to see if I could find the system control block for the IO. I cannot dump the memory via the jtag (access to invalid memory). |
| 21:52.56 | prpplague | T0mW: use devmem to check the gpio config register |
| 21:53.01 | T0mW | I'm not sure WTF the registers are located. I suspect that they are at 0xfAxxxxxx someplace? |
| 21:53.19 | prpplague | T0mW: devmem allows you to use the physical memory location |
| 21:53.40 | T0mW | prpplague: where is devmem? /sys ? /proc ? |
| 21:54.23 | prpplague | http://www.elinux.org/Hammer_Board_Software_System |
| 21:56.39 | prpplague | T0mW: surprised you don't use devmem already |
| 21:57.49 | T0mW | prpplague: first I've heard of it. |
| 21:58.18 | T0mW | prpplague: what is it? "devmem <startloc> <count>" ? |
| 21:58.22 | prpplague | T0mW: core util you should never do without |
| 21:58.32 | prpplague | T0mW: devmem 0x56000020 |
| 21:58.50 | prpplague | T0mW: that will read the physical memory location of 0x56000020 and report the value in hex |
| 21:58.54 | T0mW | with 0x56000020 being the PA not the VA. |
| 21:58.58 | T0mW | k |
| 21:58.59 | prpplague | T0mW: correct |
| 21:59.06 | T0mW | good, thanks |
| 21:59.22 | prpplague | T0mW: that way you can verify that the spi controller is acutally configured |
| 21:59.48 | T0mW | prpplague: I feel that I am only a setting away from getting this working. Of course, I have been saying that for four days now... |
| 22:01.02 | RobotGuy | T0mW: What are you doing with SPI? |
| 22:02.08 | T0mW | prpplague: I'll put that into target_skeleton |
| 22:02.11 | prpplague | RobotGuy: enc28j60 driver |
| 22:02.23 | prpplague | T0mW: devmem is being added to busybox |
| 22:02.24 | T0mW | RobotGuy: trying to get the spi working under 2.6.26-rc3 |
| 22:02.26 | RobotGuy | prpplague: Oh, cool. |
| 22:02.47 | T0mW | RobotGuy: along with mmc_spi and enc28j60 |
| 22:02.48 | prpplague | thanks to solar |
| 22:03.01 | *** join/#edev CosmicPe1guin (n=nobody@163.181.251.103) |
| 22:03.04 | RobotGuy | I need to learn how to use SPI. I have a decent handle on I2C now. |
| 22:03.21 | *** mode/#edev [+o CosmicPenguin] by ChanServ |
| 22:03.25 | prpplague | RobotGuy: you have some i2c drivers working under linux? |
| 22:03.45 | RobotGuy | prpplague: Not yet. But that is the first thing I need to get working. |
| 22:04.40 | RobotGuy | There are quite a few I2C sensors I need to be able to use. |
| 22:05.18 | prpplague | RobotGuy: hehe i'd hold off on stating that you have a handle on I2C until you get a few drivers under your belt, hehe |
| 22:05.31 | RobotGuy | Plus, thanks to another fellow, I have slave I2C code for dsPICs. |
| 22:06.00 | prpplague | RobotGuy: what protocol are they using? |
| 22:06.13 | RobotGuy | prpplague: Probably right. I am working on that. I understand the timing now. |
| 22:06.23 | RobotGuy | The slave dsPICs are using I2C. |
| 22:06.26 | prpplague | RobotGuy: do they emulate some standard i2c based gpio expanders? |
| 22:06.35 | prpplague | RobotGuy: yes i know, but what protocol? |
| 22:06.42 | RobotGuy | Just straight I2C. |
| 22:06.56 | prpplague | giggles |
| 22:07.01 | RobotGuy | prpplague: I'm not sure I understand your query. |
| 22:07.11 | RobotGuy | grins |
| 22:07.20 | prpplague | RobotGuy: thats kind of like saying "they use straight rs-232" |
| 22:07.38 | prpplague | RobotGuy: that really doesn't descibe the way the data is formated as it is transported over the rs-232 |
| 22:07.59 | RobotGuy | They just use generic I2C. Raw data. |
| 22:09.00 | RobotGuy | I2C with no data formatting. It's just raw bytes sent and received. |
| 22:09.35 | RobotGuy | Well, OK, there is a checksum sent with the data. |
| 22:09.57 | RobotGuy | Am I confused again? |
| 22:11.39 | prpplague | yep |
| 22:11.49 | prpplague | there has to be some format to the data |
| 22:12.20 | prpplague | RobotGuy: is there a document on the code for the dspics i2c code? |
| 22:12.36 | MonMotha | there really are I2C devices that only have a single register, so you just do a single byte write |
| 22:12.48 | MonMotha | those are mostly VERY simple devices like 8-bit IO expanders, though |
| 22:12.52 | T0mW | prpplague: I'm wondering if I need to config the special functions of the GPIO pins in mach-tct_hammer? |
| 22:12.57 | RobotGuy | One thing the I2C is used for is to send commands that are then transmitted to an SSC-32, which is connected to a dsPIC.. |
| 22:13.06 | T0mW | prpplague: I would have thought that the spi driver would have done that. |
| 22:13.12 | MonMotha | prpplague: know any ARMs with LCD controllers in non-BGA packages |
| 22:13.19 | RobotGuy | I am talking about smart modules that can have any sort of register format. |
| 22:13.24 | prpplague | T0mW: yes, you normally have to configure the hardware seperate in the mach_init |
| 22:13.30 | MonMotha | experimenter/one-off friendly packages (i.e. 0.1" or 0.05" spacing) would be excellent, but not required |
| 22:13.37 | prpplague | T0mW: the driver doesn't know which spi port you are using |
| 22:13.44 | MonMotha | heck, doesn't have to be an ARM, but it would be nice to be able to run Linux |
| 22:13.46 | prpplague | RobotGuy: got to have some format |
| 22:13.52 | T0mW | prpplague: yes it would, from the busnum |
| 22:14.03 | RobotGuy | prpplague: I have the full source code if you want to look at it. |
| 22:14.09 | prpplague | MonMotha: the sharp/nxp lh7952x series |
| 22:14.19 | prpplague | RobotGuy: but no docs? |
| 22:14.29 | RobotGuy | prpplague: Just what is in the source. |
| 22:14.38 | prpplague | RobotGuy: send me the source and i'll have a quick look |
| 22:14.46 | RobotGuy | OK, hang on. |
| 22:14.57 | MonMotha | prpplague: any experimenter modules ala the hammer? |
| 22:15.14 | MonMotha | I have some 640x480 TFTs to play with |
| 22:15.17 | prpplague | MonMotha: i'm sorry i didn't understand the question |
| 22:15.27 | MonMotha | I can build my own LCD controller of course, but premade is cheaper |
| 22:15.50 | MonMotha | prpplague: a module like the hammer or similar using that processor (or anything with a LCD controller capable of running Linux). Basically a breakout board |
| 22:16.03 | prpplague | MonMotha: ahh |
| 22:16.20 | prpplague | MonMotha: yea there are a few |
| 22:16.52 | MonMotha | you can run Linux on a ARM720T? |
| 22:16.56 | prpplague | MonMotha: the question really is do you want cheap with a little hacking, or a fully blown kit? |
| 22:17.00 | MonMotha | apparently you can |
| 22:17.01 | prpplague | MonMotha: hehe yea |
| 22:17.09 | MonMotha | I didn' tknow those had MMUs |
| 22:17.17 | prpplague | MonMotha: 720T does |
| 22:17.24 | MonMotha | prpplague: my goal is to just avoid having to make a custom PCB as those are kinda expensive |
| 22:17.26 | prpplague | MonMotha: 7tdmi doesn't |
| 22:17.36 | MonMotha | I have a silly project in mind, but I don't have $100s to blow on it |
| 22:17.53 | prpplague | one sec phone |
| 22:18.33 | MonMotha | need TFT LCD, I2C or SPI, UART or USB device (preferably both), and enough memory to run Linux and a 640x480x256 LCD framebuffer |
| 22:18.51 | T0mW | hmmm, S3C2410_GPE11_SPIMISO0 |
| 22:19.17 | T0mW | tries s3c2410_gpio_cfgpin(S3C2410_GPE12, S3C2410_GPE12_SPIMOSI0); |
| 22:19.18 | prpplague | MonMotha: usb on arm7 is hard to find |
| 22:19.45 | prpplague | MonMotha: but it is abvailable |
| 22:20.10 | prpplague | MonMotha: you want something that is "hackable" or a true dev board? |
| 22:20.42 | MonMotha | cost would be a concern, here |
| 22:20.49 | MonMotha | I only need to dangle a few devices off of it, though |
| 22:21.08 | prpplague | MonMotha: http://www.elinux.org/TvNow |
| 22:21.51 | T0mW | # ls /sys/class/net/ |
| 22:21.51 | T0mW | eth0 lo usb0 |
| 22:21.58 | T0mW | finally. |
| 22:22.09 | prpplague | hehe |
| 22:22.48 | prpplague | MonMotha: not sure if earthlcd still sells their lh7920 board |
| 22:22.51 | prpplague | looks |
| 22:23.05 | MonMotha | prpplague: might work. Approx cost? |
| 22:23.21 | prpplague | MonMotha: usally get the tvnow for about $20 on ebay |
| 22:23.48 | MonMotha | certainly cheaper than making my own PCB and putting stuff on it |
| 22:26.12 | RobotGuy | prpplague: The NXP LPC2468 has USB Host. |
| 22:26.32 | prpplague | RobotGuy: that come in qfp? |
| 22:26.51 | RobotGuy | prpplague: I think it does come in a QFP. |
| 22:26.58 | MonMotha | I don't need host, just device |
| 22:27.22 | RobotGuy | Lots of NXP ARM7 have USB device. Even the LPC2148 and such. |
| 22:27.38 | prpplague | RobotGuy: we are talking about a nxp device, hehe |
| 22:27.42 | MonMotha | indeed |
| 22:27.55 | RobotGuy | I have two LPC2148 boards. |
| 22:28.10 | prpplague | 2148 doesn't run linux |
| 22:28.33 | RobotGuy | prpplague: I don't know of any ARM7 that would. ARM9 for Linux. :D |
| 22:28.46 | prpplague | silly |
| 22:28.57 | prpplague | RobotGuy: ARM7 runs linux perfectly fine |
| 22:29.02 | MonMotha | LH79525 looks to do what I want |
| 22:29.30 | MonMotha | and more, of course |
| 22:29.33 | RobotGuy | prpplague: uCLinux, but I don't think ARM7 is going to run full Linux. No MMU in most of them. |
| 22:30.00 | prpplague | RobotGuy: arm7tdmi does not have mmu, arm720t does |
| 22:30.08 | prpplague | RobotGuy: same as with arm9 |
| 22:30.08 | MonMotha | LH79524 should work, too; looks like a superset |
| 22:30.14 | RobotGuy | prpplague: Oh, OK. I did not know that. |
| 22:30.35 | prpplague | RobotGuy: http://www.elinux.org/ARM_Processor |
| 22:30.48 | prpplague | MonMotha: yea the 24 is with usb slave and 25 with usb host |
| 22:30.55 | prpplague | MonMotha: but the 25 is only available in bga |
| 22:31.14 | MonMotha | ah, good thing I don't need the host |
| 22:31.23 | MonMotha | LH79524 already targetted by Linux? |
| 22:31.35 | prpplague | yea, pretty full support |
| 22:31.44 | MonMotha | cool |
| 22:31.49 | MonMotha | and that TvNow thingie has it |
| 22:32.13 | prpplague | although it has a little bit rot since sharp sold the chipset to nxp |
| 22:32.37 | prpplague | MonMotha: the pixter multimedia also has it, but it don't think it has enough ram for you |
| 22:32.39 | MonMotha | looks like I can't easily buy the QFP versions |
| 22:32.48 | prpplague | yea |
| 22:33.06 | prpplague | MonMotha: let me see if i have a couple lh79520 boards available too |
| 22:33.20 | MonMotha | the USB is optional (I can get by with a UART), but it would be nice |
| 22:33.22 | prpplague | MonMotha: we should have 20-30 prototypes around here somewhere |
| 22:36.24 | prpplague | heads home for the day |
| 22:38.16 | RobotGuy | Durn, and I just got the dualPIC sources uploaded. |

| 23:40.20 | Sienna | Um, anyone here linux serial gurus? |
| 23:41.50 | Sienna | anyone even there... ? |
| 23:41.54 | ali_as | Yup. |
| 23:42.05 | Sienna | oh good, xchat won't give me a userlist |
| 23:42.07 | ali_as | Best to ask the question. |
| 23:42.14 | zoidb | i know parellel port! |
| 23:42.27 | zoidb | heh, and i can't even spell it |
| 23:42.54 | Sienna | how the frack do I get a serial port to the hammer to work under linux? No matter what I seem to try, I can't seem to talk... I can do it in windows, but not here |
| 23:42.58 | RobotGuy | Sienna: Hi! |
| 23:43.05 | Sienna | hey Robotguy |
| 23:43.20 | zoidb | went through all the obvious settings like flow control, etc? |
| 23:43.25 | RobotGuy | Sienna: Are you trying to use the second serial port or console? |
| 23:43.28 | Sienna | shhrugd |
| 23:43.48 | Sienna | i have no idea what to do or not... linux serial i have never used before |
| 23:44.06 | Sienna | is flow control supposed to be on or off anyway? The wiki page doesn't say |
| 23:44.15 | RobotGuy | The serial ports are /dev/ttySAC0 (console) and /dev/ttySAC2 |
| 23:44.19 | Sienna | RobotGuy, console |
| 23:44.25 | Sienna | i am trying to get into the hammer |
| 23:44.42 | RobotGuy | The console defaults to 115200,8,N,1 |
| 23:45.03 | Sienna | flow control on or off? |
| 23:45.08 | RobotGuy | None |
| 23:45.21 | Sienna | ok, so how do i know its off in linux? |
| 23:45.32 | RobotGuy | That's the default. |
| 23:45.56 | Sienna | ok... then how would I talk to something? |
| 23:46.04 | Sienna | i try catting /dev/ttyS0, nothing./ |
| 23:46.17 | Sienna | i try minicom, and I think i set it up correctly, nothing |
| 23:46.28 | Sienna | help would be muchly appreciated! |
| 23:46.43 | ali_as | Have you made it work between two PCs, or between the PCs own ports? |
| 23:46.51 | RobotGuy | Set Minicom to use your preferred serial port, usually /dev/ttyS0 |
| 23:47.10 | Sienna | ali_as, i have made it work in windows and hyperterm |
| 23:47.32 | Sienna | ok, minicom is on S0 |
| 23:47.37 | RobotGuy | Set the port for 115200, 8 bits, No parity, 1 stop bit, no flow control |
| 23:47.39 | Sienna | flow is off in it. |
| 23:48.11 | Sienna | but nothing is happening. |
| 23:48.18 | RobotGuy | With that port plugged into the Carrier board serial port, you should be able to press CR (ENTER) and get a login prompt |
| 23:48.26 | Sienna | tried that, nada |
| 23:48.43 | zoidb | sienna: is your windows a dual boot of your linux box? |
| 23:48.54 | zoidb | like did you check the bios and whatnot to ensure the serial port is enabled? |
| 23:48.54 | Sienna | yes, dual |
| 23:48.55 | RobotGuy | Hmmm, that's the setup I use. Got power to the carrier board? |
| 23:48.56 | zoidb | oh ok |
| 23:49.17 | Sienna | i checked the output of setserial vs lspci, and they match |
| 23:49.25 | Sienna | so I am assuming that it is enabled |
| 23:49.37 | Sienna | RobotGuy, of course :P |
| 23:49.51 | RobotGuy | Sienna: I figured. Just checking obvious things. :) |
| 23:50.13 | RobotGuy | Do you have a known good serial cable? |
| 23:50.29 | Sienna | used it before |
| 23:50.45 | RobotGuy | Hmmmmmm. |
| 23:51.14 | RobotGuy | Seems like it should be working unless there is something wonky with your PC serial port somewhere. |
| 23:52.00 | Sienna | i agree... it should be working... however its not.... |
| 23:52.20 | RobotGuy | Can you try a different serial cable? |
| 23:53.06 | zoidb | using the same serial cable for the windows setup though right? |
| 23:53.22 | Sienna | switched to a different port, and um reset the hammer, this time got garbage out |
| 23:53.43 | RobotGuy | Sienna: Do you have permissions to read/write the serial port (in the tty group?) |
| 23:53.45 | Sienna | (using cat) |
| 23:53.54 | Sienna | i am root, i darn well hope so |
| 23:54.07 | RobotGuy | Sienna: OK, just checking. ;) Be calm. ;) |
| 23:54.30 | Sienna | ok, what the frack does minicom do when it 'initializes modem'? |
| 23:54.53 | Sienna | i can get garbage before i use minicom with cat, but after trying minicom i am back to nothing at all |
| 23:55.02 | RobotGuy | Sienna: Oh, here is something you want to do: null out ALL the modem setting commands. I forgot about that, sorry. |
| 23:55.13 | Sienna | where do i do that? |
| 23:55.26 | Sienna | and how do I undo it! |
| 23:55.28 | RobotGuy | And the result codes too. It's in modem settings. |
| 23:57.08 | Sienna | ok, nulled out all of the modem setting screen |
| 23:57.15 | Sienna | still nada |
| 23:57.55 | Sienna | wait... now minicom is saying offline |
| 23:58.03 | RobotGuy | Save your minicom settings as default, exit, and then start minicom again. |
| 23:58.16 | RobotGuy | Sienna: That is fine. It should say offline. |
| 23:58.32 | Sienna | i restarted it, it still says offline |
| 23:58.35 | RobotGuy | Can you connect to hammer now? |
| 23:58.40 | Sienna | um, how? |
| 23:58.44 | RobotGuy | Press CR |
| 23:58.56 | Sienna | still nothing... still says offline |
| 23:59.03 | Sienna | (and i pressed cr0 |
| 23:59.08 | RobotGuy | Nothing comes back from Hammer.. |
| 23:59.48 | Sienna | is minicom supposed to be saying offline? |
| 23:59.52 | RobotGuy | I don't have my replacement hammer yet, but should have it laterr this week. |
| 23:59.59 | RobotGuy | Yes, Minicom should say offline. |
