| 02:20.51 | solar | it's not that easy. You would have to describe more of your requirements |
| 02:21.37 | solar | like what distro are you using to begin with. What mini.distro is installed on your hammer |
| 02:22.09 | Mirell | In other news, the Mac Mini makes an excellent TV computer. |
| 02:22.10 | solar | and being that you said module. Sounds like you are talking about a kernel module |
| 02:31.16 | rue_shop | I have a hammer board |
| 02:31.40 | rue_shop | I need to build software to run on it, right now, the ethernet kernel module |
| 02:31.46 | solar | yes I understand what the basic hardware is. I have one myself |
| 02:31.54 | rue_shop | ok |
| 02:32.15 | rue_shop | wait, will gcc naturally compile for arm? |
| 02:32.15 | prpplague | rue_shop: the enc28j60 driver is in the mainline kernel |
| 02:32.19 | rue_shop | yea |
| 02:32.21 | prpplague | rue_shop: just need to enable it |
| 02:32.31 | prpplague | rue_shop: and add the mappings in the machine file |
| 02:32.37 | rue_shop | config.gz says its compiled as a module |
| 02:32.46 | rue_shop | but the module wasn't provided |
| 02:32.55 | prpplague | rue_shop: what config.gz? |
| 02:33.01 | rue_shop | /proc/config.gz |
| 02:33.17 | prpplague | from what kernel image? |
| 02:33.17 | rue_shop | its a compressed copy of the kernel config when it was compiled |
| 02:33.21 | rue_shop | the running one |
| 02:33.28 | rue_shop | 2.6.22 as provided |
| 02:33.31 | prpplague | bangs head on desk |
| 02:33.45 | prpplague | rue_shop: 2.6.22 doesn't have full support for the enc28j60 |
| 02:33.49 | rue_shop | cmon, I'm used to avrs :) |
| 02:34.07 | rue_shop | hmm whats 'not full support' |
| 02:34.49 | rue_shop | look at it this way, the hardware is hooked up... |
| 02:35.04 | prpplague | rue_shop: best thing for you to do is grab a copy of 2.6.29 |
| 02:35.10 | rue_shop | ok |
| 02:35.27 | rue_shop | do I use jtag to write the new kernel? |
| 02:35.28 | solar | prpplague: got any precomiled handy? |
| 02:35.44 | prpplague | solar: sorry nothing handy |
| 02:35.44 | solar | rue_shop: openocd |
| 02:35.59 | prpplague | rue_shop: you can use the jtag or just upload it to the serial console of apex |
| 02:36.22 | rue_shop | there is no /boot/ Where IS the kernel? |
| 02:37.10 | prpplague | rue_shop: ?? |
| 02:37.37 | prpplague | rue_shop: where is the kernel on what? |
| 02:37.52 | rue_shop | I'm used to the kernel being in /boot/ and a bootloader starting it up, I presume that its written to the boot vector of the arm, but I didnt see a filehandle for it |
| 02:38.08 | solar | prpplague: did you ever merge http://dev.gentoo.org/~solar/embedded/tct/src/linux-2.6.22-leds.patch ? |
| 02:38.14 | prpplague | rue_shop: you mean /boot on the root file system? |
| 02:38.28 | rue_shop | I'm used to computers running linux and small microcontrollers, this is bridging the two in ways that hurt my head |
| 02:38.36 | rue_shop | yea, there is no /boot |
| 02:39.00 | rue_shop | which I'm fine with |
| 02:39.11 | rue_shop | I just dont know how to write the new kernel |
| 02:39.14 | solar | rue_shop: it's fun when the light bulb switches from off. |
| 02:39.16 | prpplague | rue_shop: when booting a device like the Hammer, the kernel is usally stored in a flash memory location and is loaded into memory by the bootloader |
| 02:39.39 | rue_shop | does the hammer USE a bootloader? |
| 02:39.49 | rue_shop | hmm I think after 2.4 you have to |
| 02:39.52 | rue_shop | ? |
| 02:40.09 | prpplague | http://www.elinux.org/Hammer_How_to_Reflash_Apex_and_kernel |
| 02:40.26 | prpplague | rue_shop: virtually all arm devices use a bootloader |
| 02:40.29 | rue_shop | apex = bootloader? |
| 02:40.35 | prpplague | rue_shop: correcty |
| 02:41.42 | rue_shop | ok, how do I trigger the bootloader prompt? |
| 02:42.33 | rue_shop | uh, this can be done jtag too yes? It did after all come with the jtag programmer |
| 02:42.33 | solar | rue_shop: do you have serial working to the device yet? |
| 02:42.40 | rue_shop | yea, I'm talking to it now |
| 02:42.54 | rue_shop | I thought it was great using linux on a 'microcontroler' |
| 02:42.59 | solar | reboot the hammer. Do you see apex loading the kernel etc? |
| 02:43.26 | rue_shop | oh so I do |
| 02:43.43 | prpplague | rue_shop: are you familiar with the arduino bootloader? |
| 02:43.44 | solar | so you can use apex right from there to upload a new kernel |
| 02:43.50 | rue_shop | that must go by awefull fast |
| 02:44.03 | rue_shop | no I dont use bootloaders on my avr's |
| 02:44.09 | prpplague | rue_shop: ahh ok |
| 02:44.24 | rue_shop | so look like I just ^c it quick as its about to boot |
| 02:44.39 | prpplague | yea ctrl-c |
| 02:44.47 | solar | 'help' iirc |
| 02:45.45 | rue_shop | ok thats how I finish, so now I need to carve a 2.6.29 config |
| 02:45.56 | rue_shop | and work out how to compile it |
| 02:46.01 | rue_shop | then I can upload it |
| 02:46.05 | prpplague | rue_shop: same as 2.6.22 |
| 02:46.24 | rue_shop | config wise, I can take the 2.6.22 config off the.... /proc/config.gz ? |
| 02:46.44 | prpplague | rue_shop: or from the wiki pages |
| 02:46.46 | rue_shop | thinks about how to GET the config.gz |
| 02:46.56 | rue_shop | hmm |
| 02:47.01 | prpplague | rue_shop: easier to just get it off the cd or off the wiki |
| 02:47.03 | rue_shop | gets a flash disk |
| 02:47.12 | rue_shop | the cd isn't the same as whats on it |
| 02:47.26 | rue_shop | the cd dosn't ahve the enc28j stuff |
| 02:47.27 | prpplague | rue_shop: the one on the CD is a base config |
| 02:47.38 | prpplague | rue_shop: because it wasn't in the mainline kernel then |
| 02:47.49 | prpplague | wrote the enc28j60 driver |
| 02:47.52 | rue_shop | :) |
| 02:47.54 | rue_shop | OH! |
| 02:48.00 | rue_shop | question for you then! |
| 02:48.19 | prpplague | http://www.elinux.org/Hammer_How_to_build_Kernel |
| 02:48.36 | rue_shop | think the traffic on the serial lines is low enough I can bus the audio chip onto it with a different enable line? |
| 02:49.03 | *** join/#edev m4t (matt@theorize.org) |
| 02:49.03 | prpplague | rue_shop: "bus the audio chip" ??? |
| 02:50.00 | rue_shop | the audio chip also uses spi, I was going to parallel up mosi/miso with the mpeg decoder chip and use a different chip select and irq line |
| 02:50.17 | rue_shop | the only real reason for even using the audio chip is cause its output is buffered |
| 02:50.37 | rue_shop | otherwise it looks like an adc and let the arm decode the mpeg audio |
| 02:50.45 | rue_shop | but I also bought the chip now |
| 02:50.49 | prpplague | rue_shop: sorry you are going to have to be more specific as to which "audio chip" you are refering to |
| 02:50.55 | rue_shop | ok |
| 02:51.08 | rue_shop | isn't used to being on this end of the conversation |
| 02:51.13 | prpplague | hehe |
| 02:51.20 | prpplague | rue_shop: np, i can be patient |
| 02:51.45 | rue_shop | vs1053, mpeg decoder, I have the sparkfun carrier board |
| 02:51.59 | prpplague | ahh |
| 02:52.04 | prpplague | has a quick look |
| 02:52.28 | rue_shop | they mess up the serial line names, but its spi |
| 02:53.31 | prpplague | spi from the hammer should work fine |
| 02:54.34 | rue_shop | to share spi0 between the enc28j and the vs1053 (with say GPH1 as select and EINT11 as dreq) |
| 02:55.14 | prpplague | rue_shop: naw, can't share spi with the enc28j60, too much demand |
| 02:55.22 | rue_shop | thats what I wondered |
| 02:55.28 | rue_shop | so I'll use isp1 then |
| 02:55.41 | rue_shop | lose the sd func (which I dont need) |
| 02:56.12 | prpplague | rue_shop: yea that would work |
| 02:56.19 | rue_shop | actaully I suppose I dont lose it as much as enounter traffic issues if trying to use both |
| 02:56.38 | rue_shop | seeing as ttraffic will be ether->decoder should be ok |
| 02:56.43 | rue_shop | ok |
| 02:56.53 | prpplague | rue_shop: actually you can use the sd/mmc via a gpio bit bang spi |
| 02:57.18 | rue_shop | is there a kernel driver to make that easy? |
| 02:57.24 | prpplague | yea |
| 02:57.27 | rue_shop | cool |
| 02:57.41 | rue_shop | ok, try to recude this to 4 things at once |
| 02:57.45 | rue_shop | .. |
| 02:57.47 | rue_shop | :) |
| 02:58.18 | rue_shop | looks for kernel url, hopefully something more fitting than ftp.kernel.org |

| 03:07.18 | rue_shop | the rootfs starts at the 1M mark then? |
| 03:08.05 | rue_shop | wait, so kernel 2.6.29 from ftp.kernel.org comes with the enc28j driver? |
| 03:08.31 | rue_shop | man I have to spend like 45 mins turning junk off on a default full kernel tho |
| 03:09.51 | rue_shop | takes a quick break |
| 03:10.05 | rue_shop | is step 1 to download 2.6.29 from ftp.kernel.org? |
| 03:11.44 | solar | rue_shop: why would it take 45mins to load the config.gz ? |
| 03:14.08 | rue_shop | no, it takes me 45 min to go thu the defualt config of a ftp.linux.org kernel and turn off all the goofy stuff nobody ever uses, then work out what I screwed up and turn things on to enable turning things on I need |
| 03:14.48 | rue_shop | ok -> with a 'fresh' pc, I want to upgrade my hammers kernel <- |
| 03:15.05 | rue_shop | I think I really need to start with uclibc! |
| 03:16.33 | rue_shop | I got buildroot, but I dont think I need it, cause I'm fine with the rootfs |
| 03:17.27 | rue_shop | the pdf on the cd kinda skips some of the initial downloading steps |
| 03:18.29 | rue_shop | is buildroot uclibc? |
| 03:18.30 | rue_shop | arg |
| 03:19.27 | rue_shop | so buildroot is needed to make uclibc |
| 03:19.35 | rue_shop | which I need to make the new kernel |
| 03:19.58 | rue_shop | and uclibc has a config, which I dont know how to config yet... or do I have a config for it on the cd... |
| 03:20.33 | rue_shop | buildroot-hammer-config |
| 03:20.46 | rue_shop | ok and apex is the bootloader |
| 03:20.57 | rue_shop | its starting to clear up |
| 03:21.40 | rue_shop | shall I assume buildroot uses .config like the kernel does? |
| 03:22.56 | rue_shop | I think that worked |
