We really don't want to even start going into the game of enabling random devices as =y on the default config, otherwise we'll end up with a 30MB kernel on all boards. I agree, but the fact is we have no board which works really fine ATM. See: http://en.opensuse.org/openSUSE:Supported_ARM_boards#13.1 There are only RPi and Chromebook which have a correct support (and they use _downstream_ kernels). But chromebook boot only once and need a hack to boot then (I am on it, Marcus gave me some hints to fix that using kiwi hooks) and had a lot of X stability problems (random freezes, X crash when switching VT). Raspberry Pi is not booting at all as is (kiwi partitioning bug) and need a hack to get a bootable image: http://en.opensuse.org/HCL:Raspberry_Pi#Known_Issues Maybe Beaglebone or Beaglebone black have a good support? (I do not have such devices and there is no feedback on our wiki) Now, SABRE Lite is the only board where I got graphics working with upstream kernel. The last blocking problem on this board is USB which is not working, even with imx_v6_v7_defconfig. The main things to do for boards support are : 1) Get boards booting Linux (should be a minimum). 2) Have a maximum number of supported devices (USB, sound, video, etc.) on each board (even if it does mean to have '=y' instead of '=m'). 3) Clean-up / fix our kernel / kernel configs to use modules (=m) instead of built-in (=y) when it is possible. I think we should use again our Trello board or setup a wiki page or something to write down what must be done for each board and who is taking care of each task. What do you think about that?

Re: [opensuse-arm] Installing on semi-custom OK210 board.....

Thank you very much for bringing some light into this... I got the files from the manufacturer.... They built U-boot, then the linux kernel...then the created the image for flashing the board... Everything in Ubuntu Now, I am trying to do it on opensuse.... 1.-Building U-boot.. I get the following: make: arm-none-linux-gnueabi-gcc: Command not found I got the ARM crosscompiler in opensuse... cross-armv7hl-gcc47-icecream-backend - The GNU C Compiler and Support Files Is that the … [View More]equivalent of the gnueabi??? I tried to find some answer online, but everything is for another distribution... not Suse... How can it be done using the suse x-compiler???

The point is that there are no generic instructions, it does highly depend on the board. Usually the manufacturer's website has either instructions how to do it or a downloadable image that you can peek at using parted etc. Finding that information or figuring it out is the biggest obstacle in adding board support... Which bootloader(s) are required for the board? While I don't know the OK210, I have access to a board with an S5PV210: The armStoneA8 uses a preinstalled proprietary firmware NBoot in flash, which then loads U-Boot - also in flash. Other boards load U-Boot from an offset inside an unformatted first partition on the SD card, the Raspberry Pi even from a FAT partition. How can your bootloader load the kernel? U-Boot imposes how to further set up your partitions - in the best case your U-Boot is upstream and/or supports (or can be patched to support) ext4, then you can do one big ext4 partition with rootfs and kernel. Otherwise you'll have to prepend another partition for kernel/initrd, with preference from ext3, ext2 down to fat - I usually take ~100MB. Preference is usually for booting from SD card because of flexibility to fix on another machine or to some day exchange it in case of wear. Other boot options might include USB, SATA, TFTP and NFS. Which kernel format to choose? If bootz command is available in U-Boot, use a zImage; otherwise use a uImage (bootm command). Device trees S5PV210 does still not support the multi v7 kernel config upstream, so you can likely ignore anything you read about .dtb files for now. Graphics Note that the S5PV210 has a PowerVR SGX540 GPU, for which no real Open Source driver exists today: http://powervr.gnu.org.ve/doku.php HTH, Andreas -- SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer; HRB 16746 AG Nürnberg -- To unsubscribe, e-mail: opensuse-arm+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-arm+owner(a)opensuse.org [View Less]
