**** BEGIN LOGGING AT Mon Jun 17 02:59:58 2013 Jun 17 06:52:23 mornin` av500! Jun 17 06:54:21 gm Jun 17 06:57:13 all working code is up on git, need to refactor it some more. Jun 17 06:58:32 wanted today to dive into getting kernel to u-boot but i lack a bit of knowledge about u-boot what kernel args are needed, how to configure u-boot to automatically switch to usb network at start Jun 17 07:08:55 i need to pass kernel + device tree + inird, right? Jun 17 10:29:29 av500: have some time to discuss about u-boot? Jun 17 10:43:36 sure Jun 17 10:44:37 first of all i see that u-boot automatically tries to boot from eMMC/MMC when the board is up Jun 17 10:44:57 that script is hardcoded when u-boot is compiled ? Jun 17 10:45:29 you can override that with uEnv.txt Jun 17 10:45:34 or change the hardcoded values Jun 17 10:48:43 change the hardcoded values in our case i think Jun 17 10:50:31 so my script should be like setenv ethact usb_ether; dhcp; tftp loadAddr kernel; tftp loadAddr dtbs; Jun 17 10:50:41 and with the initrd where should i put it / Jun 17 10:50:56 *? Jun 17 10:51:55 sec Jun 17 10:52:57 <_av500_> http://pastebin.com/QZmAtXUQ Jun 17 10:53:05 <_av500_> this is what I uses for tftpboot Jun 17 10:53:22 <_av500_> ignore the nfs stuff Jun 17 10:53:30 <_av500_> also, the device tree can be appended to the kernel Jun 17 10:53:39 <_av500_> for a start, get the kernel loaded Jun 17 10:53:46 <_av500_> initrd can be the next step Jun 17 10:54:54 and what arguments to pass to the kernel, conole=ttyO0? and what else? Jun 17 10:55:10 defaults Jun 17 10:55:19 most should be set already Jun 17 10:56:32 the console is right? ttyO0? and for baudrate 115200n8? Jun 17 11:00:22 yes Jun 17 11:00:53 perfect, maybe by 2night will have kernel panicing because no initrd :) Jun 17 11:02:04 also because 2day is the official day of the coding for gsoc, every week need to have some goals and acomplish them? how do we work from now on, any special directives? :) Jun 17 11:04:07 lo Jun 17 14:34:52 av500: is there any posibility to remove cpsw from u-boot? if usb_ether fails it goes to cpsw and if cpsw fails too again to usb_ether... Jun 17 14:36:48 I guess so Jun 17 14:36:56 some #define or so Jun 17 14:37:01 Tartaturs might know Jun 17 14:39:17 eh screw it, going to deal with it like this Jun 17 14:55:42 av500: have any link to a precompiled kernel ? Jun 17 14:56:09 my mmc card is emtpy, did not think i will need it for now Jun 17 14:56:51 http://downloads.angstrom-distribution.org/demo/beaglebone/ Jun 17 14:57:17 grab one from Angstrom-systemd-image-eglibc-ipk-v2012.12-beaglebone.rootfs.tar.xz Jun 17 14:57:29 ok, perfect! Jun 17 14:57:33 or build your own, you'll need that anyway Jun 17 14:58:04 https://github.com/beagleboard/kernel Jun 17 14:58:07 3.8 branch Jun 17 15:04:13 u-boot tftp implementation wants block_number from 0 not from 1, the rest were ok with 1 :) Jun 17 15:04:29 need to make a text file with all these bits and pieces to remember them for later Jun 17 15:08:20 yes Jun 17 15:11:18 av500: i`ll be afk a couple of hours, will leave you a message when i have kernel transferred and code commited. Jun 17 15:14:20 np Jun 17 16:54:31 av500: success! got kernel to panic because no root device Jun 17 20:33:06 _av500_: ping Jun 17 21:02:54 <_av500_> yo Jun 17 21:02:58 <_av500_> tomorrow Jun 17 21:08:07 perfect, until 2morrow i will have an initramfs running there too. good night! Jun 17 21:14:25 <_av500_> :) Jun 17 21:54:39 ds2: ping **** ENDING LOGGING AT Tue Jun 18 02:59:59 2013
