wiped u-boot enviroment

[xhpohanka]

Hi Codesnake, thank you for your work on OpenELEC.

I have unbranded g18 board (same as Matricom MX2) and I got it with erased nand flash. I have build openelec from source and flashed it using sd card recovery. Unfortunately I see on serial line that there is some problem with booting. It seems to me, that u-boot does not know partition names (logo, boot, etc.) - mtdparts variable is not defined. Is it normal?

I'm able to boot openelec manually by loading kernel from sd card and running bootm command. Can you please share what u-boot enviroment variables has to be set?

regards Jan

NAND partition table is not stored in u-boot environment variables. It is defined in kernel device tree.

[codesnake]

At each boot kernel reads NAND partition layout from device tree and updates it in NAND environment area. During firmware install first time this is performed by recovery's kernel. Then u-boot reads parition layout from NAND environment area and boots from boot partition.

Then I do not understand why my device does not boot with clean install. Maybe there are some bad blocks around env area.

I'm getting big number of similar warnings during kernel booting
