| 00:37.35 | joe_bleau | GPSFan: there's a bit in the u-boot FAQ about running from ram; it's not possible or supported... (lol) |

| 02:59.42 | cougarvt | does anyone use jtag tools with their juicebox? |
| 02:59.47 | cougarvt | or in general |
| 03:00.04 | joe_bleau | I'm on winblows, mostly, so I tend to use OCD Commander |
| 03:00.15 | joe_bleau | (arm, ppc405, mpc850, cpu32) |
| 03:00.49 | cougarvt | yeah - that's been recommended to me. i just found out that we have it at work too. maybe i'll give it a go but i'm linux only at home |
| 03:01.22 | cougarvt | i'm playing with your test code but i need to stop the jb before copying the program in |
| 03:01.28 | joe_bleau | It's free. Under linux, you'll need a raven or better. Under windows, wigglers are supported. |
| 03:02.10 | cougarvt | forgive my ignorance but the .elf file is what i should copy to the jb |
| 03:02.33 | cougarvt | yeah we have a raven but i haven't looking into it yet |
| 03:02.48 | joe_bleau | What I'd like to know: does the Chameleon emulate a raven well enough to fool OCD Commander under Linux? (http://www.amontec.com/chameleon.shtml) |
| 03:02.48 | GPSFan | joe_bleau: hehe, I guess I didn't know that when I got ppcboot1.1.2 then 1.1.6 working from ram... ;>) |
| 03:03.37 | joe_bleau | cougarvt: yeah, .elf if your jtag tool supports it. |
| 03:03.52 | cougarvt | also fyi - i dumped the lcd_2.elf file and made a script to poke each value to the correct address |
| 03:03.52 | joe_bleau | If not, just use objcopy to convert to binary, s-record, intel hex, whatever it needs. |
| 03:04.09 | cougarvt | dumped with hexdump that is |
| 03:04.20 | joe_bleau | Did you parse the .elf file? |
| 03:04.25 | joe_bleau | It's not a straight binary image |
| 03:05.09 | joe_bleau | GPSFan: I got it to boot, but it's still confused about the flash. |
| 03:05.23 | joe_bleau | Too many assumptions in the code |
| 03:06.11 | cougarvt | i used hexdump to output the file in hex values then poked each register (starting at 0x10001000) with the vlaues |
| 03:06.20 | cougarvt | s/vlaues/values/ |
| 03:06.42 | joe_bleau | Yeah, I don't think that will work. If you want to do it that way, convert to a binary image first |
| 03:07.07 | cougarvt | i'll give that a shot (it doesn't work - the lcd just goes blank) |
| 03:07.32 | cougarvt | however - do i need to stop the jb first? or can i just copy this in with the demo running? |
| 03:08.47 | joe_bleau | Yeah, halt the cpu |
| 03:09.07 | joe_bleau | You'll need to mod the makefile to build a binary file...something like $(OBJCOPY) -R .stack -S -O binary $(PROJECT).elf $(PROJECT).bin |
| 03:09.10 | cougarvt | that's why i came here - to see if anyone know's how/if jtag tools can |
| 03:09.15 | joe_bleau | (I think, untested) |
| 03:09.24 | cougarvt | i'll play around with it. thanks |
| 03:09.39 | joe_bleau | Oh, and the lcd_2 demo is set to run at 0x0c001000 |
| 03:09.54 | joe_bleau | You can, of course, mod the link script to move it |
| 03:11.11 | cougarvt | oh is the wiki correct? |
| 03:11.15 | joe_bleau | Wow, the wiki jtag tool section is pretty bare |
| 03:11.19 | joe_bleau | About? |
| 03:11.37 | cougarvt | it says to set 0x0c001000 to 0x08 but copy the bin to 0x10001000 |
| 03:11.44 | cougarvt | at least that's how i read ti |
| 03:11.56 | cougarvt | i know - i'm writing it as i learn |
| 03:12.08 | joe_bleau | Cool |
| 03:12.29 | joe_bleau | Oh, ok...0x0c01000 is a CPU configuration register |
| 03:12.46 | joe_bleau | By writing 0x08 to it, you disable the onchip cache and convert it to sram |
| 03:12.57 | joe_bleau | There's not much there (4k?), but it's handy |
| 03:13.21 | cougarvt | however the bin should be copied to 0x10001000? |
| 03:13.29 | joe_bleau | s/0x0c01000/0x01c00000/ |
| 03:13.34 | joe_bleau | Which? |
| 03:13.41 | joe_bleau | Examine the .dld files. |
| 03:13.56 | joe_bleau | They show you the memory map the program was linked to |
| 03:14.25 | joe_bleau | lcd_2.dld shows all the sections going to ram (>RAM) |
| 03:14.48 | joe_bleau | Which is defined near the top of the link script as (RAM (rw) : ORIGIN = 0x0c001000, LENGTH = 0x00010000) |
| 03:14.53 | cougarvt | cool - "SRAM (rw) : ORIGIN = 0x010001000" |
| 03:15.15 | joe_bleau | But scroll down...all the section in lcd_2 are assigned to RAM, not SRAM |
| 03:16.52 | joe_bleau | But compare to nand_1.dld; there you see the sections get shoved into RAM, which is defined at 0x010001000 (the onchip sram array) |
| 03:17.00 | joe_bleau | Hey, there's a typo! Good catch. |
| 03:17.24 | cougarvt | :) |
| 03:17.35 | joe_bleau | People really should attempt to comment or explain demo code before posting it. Grrr. |
| 03:20.01 | joe_bleau | GPSFan: we have a licensed copy of that Macraigor flash tool at work; it supports the MPC850! |
| 03:23.39 | GPSFan | joe_bleau: swell |
| 03:23.51 | joe_bleau | Makes things a little easier. |
| 03:35.03 | sunrunner20|game | interesting |

| 04:51.59 | cougarvt | not sure if you're still here joe but if so thanks for the info. i figured out i was mixing the instructions for 2 different packages on the wiki (lcd2 and nand1) |
| 04:52.36 | joe_bleau | Yeah, not surprising. |
| 04:52.37 | cougarvt | haven't had much luck though and i think i'm going to search for better jtag hardware and get a windows vm up |
| 04:52.52 | joe_bleau | That section of the Wiki is really vague. |
| 04:53.11 | joe_bleau | I'm the wrong person to ask about arm jtag under Linux |
| 04:53.44 | cougarvt | i saw the jb on make today. hope the hackers come in force to push this as far as i can go (and guide us newbs along the way) |
| 04:54.16 | cougarvt | yeah - jtag tools seems to be one of the better packages and it's got a bit to go still |
| 04:54.20 | joe_bleau | Sometimes I think the Wiki is a little too restrictive |
| 04:54.31 | joe_bleau | If you get stuck, it's not a good medium to ask questions. |
| 04:54.58 | joe_bleau | The irc channels are worthless if there's no one around that knows what is up |
| 04:55.11 | joe_bleau | At least with the JB, there's a section on the i-appliance BBS |
| 04:55.17 | cougarvt | i agree - that's why i come here. i feel bad though - i don't want to butt in with a jb question when there is a good walnut conversation going |
| 04:55.56 | cougarvt | haha - earlier today people were talking up a storm then prpp left and the chatter died instantly |
| 04:56.05 | joe_bleau | Seems to me it's as ontopic as anything else |
| 04:56.21 | joe_bleau | I rarely get to chat with prpp |
| 04:57.10 | cougarvt | you two seem to have your name on most of the wiki pages. you must get a lot of chatter directed at you |
| 04:57.33 | joe_bleau | Not me. prpplague is the master of the JB. |
| 04:57.52 | joe_bleau | My memory is fuzzy on the details, since it's been awhile. |
| 04:58.12 | cougarvt | i'd like to see a resurgance in the JB. it'll keep me moving on it. |
| 04:58.20 | joe_bleau | And those example code snippits are rough, as you've noticed. |
| 04:58.33 | cougarvt | it's supposed to be a springboard proj for me but i rarely have time for it anymore |
| 04:58.36 | cougarvt | that i have |
| 04:58.55 | cougarvt | my toolchain is lacking at the moment too so i can't recompile |
| 04:59.11 | joe_bleau | I had a blast just writing code and running little test programs |
| 04:59.34 | cougarvt | still my jtag hardware is lacking more - i can't copy any code onto the jb yet |
| 04:59.45 | joe_bleau | wiggler? |
| 04:59.59 | cougarvt | yeah - i even enjoy flipping bits |
| 05:00.01 | cougarvt | DLC5 |
| 05:00.18 | cougarvt | i do plan on building a wiggler though (dlc5 is a xilinx btw) |
| 05:00.37 | joe_bleau | Yeah, it's pretty simple to build. |
| 05:01.01 | cougarvt | i can't bring myself to drop $400 on a jtag device so i try to get buy with the free stuff |
| 05:01.02 | joe_bleau | I'm told that many of the open source arm jtag debug tools can be modified for the Xilinx hardware |
| 05:01.15 | joe_bleau | I use the $20 olimex wiggler for arm and ppc405. |
| 05:01.33 | joe_bleau | I think a nice DIY wiggler would probably work as good, if not better. |
| 05:01.47 | cougarvt | yeah i've worked on it a little but i'm sick of having to write the tools before i can use them. i don't want to write jtag software, i want to code for the jb |
| 05:01.48 | joe_bleau | One '244 and a transistor, handful of resistors |
| 05:02.08 | joe_bleau | I'm trying to remember if there was some chatter at the BBS about alternate tools |
| 05:02.18 | joe_bleau | There's just *got* to be something out there ready to go |
| 05:02.19 | cougarvt | yeah - i am cooking up a hardware hacking kit that i will build a wiggler into |
| 05:02.33 | joe_bleau | arm7tdmi is so common anymore, and the debug docs are public |
| 05:03.09 | joe_bleau | Looked into arm-boot or jflash-linux? |
| 05:03.17 | cougarvt | you would think. i didn't have much luck finding it though. still i've only been using jtag for ~2mo so i could chalk it up to inexperiance |
| 05:03.30 | cougarvt | i will now |
| 05:05.19 | cougarvt | any idea if jflash-linux supports the dlc5? |
| 05:06.01 | joe_bleau | Not sure |
| 05:06.46 | cougarvt | i'll soon have a gumstix to play with too... |
| 05:09.01 | joe_bleau | armtool? |
| 05:12.17 | joe_bleau | Sounds like it can upload and run code, and work with the Xilinx adapter: http://hri.sourceforge.net/tools/jtag_faq_org.html#_Toc63218739 |
| 05:14.34 | cougarvt | looks good. i'll have to get back to you on it |
| 05:15.16 | joe_bleau | You don't need to get back to me! |
| 05:15.38 | joe_bleau | If you come up with something that works, add it to the Wiki instead. |
| 05:16.08 | joe_bleau | jtagger? |
| 05:16.14 | joe_bleau | http://jtager.sourceforge.net/ |
| 05:16.34 | joe_bleau | Oops, wiggler only |
| 05:17.10 | cougarvt | yeah - i started working on a dlc5 driver for jtagger |
| 05:17.28 | joe_bleau | I've got a digilent adapter...wonder if it's the same? |
| 05:17.38 | cougarvt | didn't work out and i'm more interested in the jb |
| 05:17.51 | cougarvt | from what i read there are a lot of wiggler clones |
| 05:18.13 | joe_bleau | It's nothing more than a few level shifters on the parallel port |
| 05:18.16 | cougarvt | honestly the xilinx dlc5 just has a different pinout |
| 05:18.21 | cougarvt | right |
| 05:21.22 | joe_bleau | Looks like jtagger has some hard coded assumptions about the polarity of the wiggler signals |
| 05:21.35 | joe_bleau | Moving pins around wouldn't be too hard; that all in an include file |
| 05:40.52 | cougarvt | hrm..well armtool built but i'm too tired to make much of it. |
| 05:41.08 | cougarvt | thanks for the pointers. you'll see my progress on the wiki |
| 05:41.46 | cougarvt | night joe |
| 05:44.55 | joe_bleau | Later! |

| 17:27.34 | prpplague | something like that |
| 17:28.08 | ZeZu | i dont remember what the page said, once you do what you need to do with jtag, it writes it permanently for juicebox to the rom right? If i send you mine can you write to it and send it back ? I still do want to play with the fucker ;| but those pads are tiny, i'd like cover half the board in solder before i got the wire to stick hehe |

| 17:33.24 | ZeZu | ko |
| 17:39.38 | joe_bleau | prpplague: I was fielding jb jtag under linux questions last night, so I was in way over my head |
| 17:39.56 | joe_bleau | I need to download and improve the docs on jtag+jb |
| 17:40.06 | joe_bleau | Any suggestions on the jtag software? |
| 17:40.11 | prpplague | joe_bleau: hehe, naw, answer questions tends to clarify your own understanding |
| 17:40.15 | joe_bleau | Download, halt, go |
| 17:40.37 | prpplague | jtager works nicely for debugging |
| 17:40.52 | prpplague | the jtag app from openwince seems to be the best for flashing |
| 17:40.55 | joe_bleau | We did discuss it |
| 17:41.12 | joe_bleau | I'm thinking more in terms of downloading the example code |
| 17:41.27 | prpplague | then the jtag app from openwince |
| 17:42.25 | prpplague | joe_bleau: http://www.elinux.org/wiki/UsingJtagTools |
| 17:42.53 | prpplague | joe_bleau: it supports several jtag dongles |
| 17:43.01 | prpplague | joe_bleau: and seems to be pretty easy to modify |
| 17:43.22 | joe_bleau | I thought that one was set up to read the BSDL file? |
| 17:44.14 | prpplague | it can use the bsdl as well |
| 17:44.23 | prpplague | joe_bleau: for programming flash and such |
| 17:44.58 | prpplague | joe_bleau: but it can interface with the cpu for loading applications |
| 17:45.08 | prpplague | joe_bleau: its what i used to load your test apps |
| 17:45.14 | joe_bleau | Now, can it parse and download an .elf file to ram? |
| 17:46.40 | prpplague | i dont believe so |
| 17:46.49 | prpplague | its mainly binary files |
| 17:46.53 | joe_bleau | OK |
| 17:47.17 | prpplague | i so rarely do anything with that method |
| 17:47.34 | prpplague | i usually am concerned with just bootloaders and/or diagnostic apps |
| 17:52.06 | prpplague | i've got so much work to do, i have no clue where to begin |

| 19:14.03 | joe_bleau | Right now, I'm trying to finish the patch for a ram-resident u-boot for the DHT-Walnut |
| 19:14.23 | joe_bleau | Then I may dig out the jb and try out the linux jtag stuff, if I can keep my linux box running |
| 19:14.40 | prpplague | hehe |
| 19:23.04 | joe_bleau | What's the preferred cvs diff command line arg for generating a patch set? |
| 19:23.12 | joe_bleau | I've been using cvs diff -u |
| 19:25.41 | prpplague | joe_bleau: -un |
| 19:26.02 | prpplague | or atleast that is what i prefer for patches i get for buildroot and busybox |
| 19:26.54 | joe_bleau | That's quite a bit harder to read |
| 19:26.54 | prpplague | sorry -uN |
| 19:27.10 | prpplague | typo |

| 19:27.28 | prpplague | the -N is mainly for new files |
| 19:27.47 | joe_bleau | Yeah, much nicer |
| 19:34.54 | prpplague | joe_bleau: later |
| 19:38.14 | cougarvt | joe_bleau: i notice you are fishing for more info on linux jtag. hope i inspired that |
| 19:38.53 | cougarvt | i was just playing with jtag tools and noticed the flashmem command which does what i was trying to do yesterday. |
| 19:39.18 | cougarvt | haven't tried it out but if there are others out there that want to help figure out the jb using linux tools i'm all for it |
| 19:39.21 | joe_bleau | cougarvt: nice |
| 19:40.32 | cougarvt | i left my iron at work so i'll take my jb in tomorrow and ease the debugging process. for now i need to read up on the S3C44B0X. |
| 19:40.51 | joe_bleau | That's an excellent idea. |
| 19:41.01 | joe_bleau | There's a lot to play with in that CPU...many options. |
| 19:42.01 | cougarvt | so i am seeing. i need to get an easier to use rs232 device wired in though so i can start using it for debug/testing |
| 20:22.22 | cougarvt | one bit of info that would be good for the wiki is how to start and stop the jb using openwince jtag tools (if anyone knows) |
| 20:49.42 | joe_bleau | GPSFan, dfarnsworth: I've posted a ram-resident u-boot and patch to the Wiki. I'd really appreciate someone else with JTAG giving it a try. Or testing the patch. |
| 20:51.07 | agaffney | ram-resident? |
| 20:51.16 | agaffney | I know what that means, but what does it mean in this case? :P |
| 20:51.37 | joe_bleau | Recovery from a bricked walnut. |
| 20:52.00 | joe_bleau | If you hose the flash, you can download this to sdram and use the ram-resident u-boot to burn a new copy of u-boot into the flash |
| 20:52.34 | joe_bleau | It's not anything new; GPSFan did a ram resident ppcboot some time ago |
| 20:52.50 | joe_bleau | It's only useful if you have jtag running |
