Other Parts Discussed in Thread: TPS65218
Tool/software: Linux
Dear Sir,
We designed a board based on am437x-gp-evm. I am trying to boot from eMMC. I have changed "boot part " to "1:2" in uboot source code to boot from eMMC.
Now i am getting below error while boot from eMMC.
U-Boot SPL 2015.07-00114-gf8d68d1-dirty (Apr 12 2017 - 16:23:48)
SPL: Please implement spl_start_uboot() for your board
SPL: Direct Linux boot not active!

if i enter below command from u-boot# prompt,
"setenv finduuid part uuid mmc 1:2 uuid "
After giving above command, it is booting from eMMC properly. But when i reset the board,It is not booting and it gives same error which i have mentioned above.
How do i save above variable to eMMC ?
If i enter "saveenv" , it gives below error
"Saving Environment to FAT...
Card did not respond to voltage select!
** Bad device mmc 0 ** "
How do i solve this issue?
