AM3358: Saveenv fails

Hi,

The customer can save variable successfully in BBB, but failed in his custom board. Any other suggestion?

Can they add #define DEBUG line in the very beginning of <Processor SDK>/board-support/u-boot-<version>/include/configs/am335x_evm.h file and attach the new log right after executing saveenv command?

=> saveenv

Hi,

Thanks for following the case.

The customer has already solved the problem. Because the cd pin in his board is different from evm, it can be saved now. But after rebooting, uboot prompts to successfully read the saved environment variables, but the environment variables are default values instead of being saved in uEnv. He used text to view the environment variable and it seems has been successfully saved. 

From which device or partition the environments gets loaded are saved back to the same place. Once the environment content is saved, the same content should be read back, unless you see the *** Warning - bad CRC, using default environment message. This message indicates that the uboot.env had a bad CRC and the default U-Boot environment will be used. Please, see this thread for more details.
