Title: 3.10 kernel on A13-OLINUXINO
Post by: aikipooh on December 09, 2013, 11:04:29 pm
Does anybody have a working subj?
I have a board, and 3.4 kernel works ok. I'm trying to run 3.10 from the expiremental branch, but it always hangs on startup.
The uEnv.txt is like follows:

Quote#dtb_file=script.bin.3.4
#img_file=uImage.3.4
dtb_file=sun5i-a13-olinuxino.dtb
img_file=uImage.3.10

mmc_load_image=ext2load mmc 0 0x48000000 ${img_file}
mmc_load_dtb=ext2load mmc 0 0x41000000 ${dtb_file}

mmcargs=setenv bootargs console=ttyS0 root=/dev/mmcblk0p1  rw rootwait panic=10
fdtargs=setenv fdt_high 0xffffffff;setenv initrd_high 0xffffffff
# noinitrd  ssp1=mmc ext3 fixrtc

xyz_mmcboot=run mmc_load_image; run mmc_load_dtb; echo Booting from mmc ...
uenvcmd=run xyz_mmcboot; run mmcargs; run fdtargs; printenv; bootm 0x48000000 - 0x41000000


Maybe there's something blatantly wrong here?

You can start the kernel manually via u-boot commands. Put kernel image(uImage) and dtb into uSD boot partition then type:

fatload mmc 0 0x46000000 uImage

fatload mmc 0 0x49000000 something.dtb (sun4i-a10-cubieboard.dtb or sun5i-a13-olinuxino.dtb)

env set fdt_high ffffffff

bootm 0x46000000 - 0x49000000


Warning: the rootfs must be embedded into uImage or use rootfs via NFS

Enter u-boot commands pressing any button during u-boot start  ;)

Thank you very much, vinifr!

I've asked in IRC yesterday, indeed, I was trying to boot a kernel without MMC support and without rootfs. Trying hansg's branch now. With early_printk I see it hangs on "Waiting for root device /dev/mmcblk0p1...". I'll try to compile a kernel myself now and see where I'm wrong:) At least I moved forward a little bit.

Actually

But mmc support still doesn't work. https://groups.google.com/forum/?fromgroups=#!topic/linux-sunxi/prLRvZAHFvc (https://groups.google.com/forum/?fromgroups=#!topic/linux-sunxi/prLRvZAHFvc) In which case use rootfs embedded into uImage like above

Ah, I see. It stalls on obtaining root.
