/boot destroyed how I can retore

[damien78]

HI,

On my cubietruck I can boot form sd card my filesysteme on SATA. But y can't boot form nand.

I must use kernel 3.4.108 because alsa spdif pass trought do not work on 3.4.109.

I can't use nand install script because it formating sata drive.

here /boot :

drwxr-xr-x  4 root root   16384 Jan  1  1970 ./drwxr-xr-x 23 root root    4096 Sep  6 09:46 ../drwxr-xr-x  2 root root    2048 Nov 11 15:33 bin/-rwxr-xr-x  1 root root  118912 Nov 18  2014 boot.axf*-rwxr-xr-x  1 root root    1745 Nov 11 15:30 boot.cmd*-rwxr-xr-x  1 root root     106 Nov 18  2014 boot.ini*-rwxr-xr-x  1 root root    1817 Nov 11 15:30 boot.scr*-rwxr-xr-x  1 root root   97046 Oct 14 20:33 config-3.4.109-sun7i*-rwxr-xr-x  1 root root 3110638 Nov 11 14:40 initrd.img-3.4.108-cubietruck*-rwxr-xr-x  1 root root 3115996 Nov 11 15:33 initrd.img-3.4.109-sun7i*drwxr-xr-x  2 root root    2048 Nov 18  2014 linux/-rwxr-xr-x  1 root root     512 Jan  1  1980 magic.bin*-rwxr-xr-x  1 root root   46360 Nov 11 15:33 script.bin*-rwxr-xr-x  1 root root 2004410 Oct 14 20:33 System.map-3.4.109-sun7i*-rwxr-xr-x  1 root root     256 Nov 11 15:33 uEnv.txt*-rwxr-xr-x  1 root root      64 Nov 11 15:33 uImage*-rwxr-xr-x  1 root root   14056 Nov 11 15:32 upgrade.log*

Hi,

 

From my point of view if you may boot from NAND boot (3.4.109 kernel's image) is possible that you might mount NAND1 (boot partition) after boot from SD card and just copy files from /boot directory with expected kernel file to /boot on NAND1 partition. Of course you should change path into uEnv.txt regarding root filesystem. If my thinking is wrong please let me know :-)

Hi,

U-boot cannot boot kernell zImage (compressed image) but only uImage.

 

I dont know do with other file boot.cmd boot.scr

 

I change path in uEnv.txt but y have only a black screenand nothing else.

 

Regards.

You need to convert the kernel to uImage this way:

mkimage -A arm -O linux -T kernel -C none -a "0x40008000" -e "0x40008000" -n "Linux kernel" -d zImage uImage
