Hi
We are using ATCA equipment and those boards have redundant boot banks and they are managed by IPMI controllers. So while you are you are running Linux, you can change the boot banks for next restart through set boot options IPMI command. The problem arises when we write the U-Boot env variables using fw_setenv and immediately send the IPMI command to switch the boot bank.
This is a flaw in the IPMI software implementation, the IPMI controller should only switch banks when the payload power is off.
