If the master boot mode is SD card boot and the backup boot mode is eMMC boot, EVM board can not be booted.

Do you not see any logs at all? Like the SBL/SPL might be booting but failing later?

Hi Prashant,

Sorry, I get new information, 

If the master boot mode is SD card boot and the backup boot mode is eMMC boot, EVM board can be booted, but it will delay about 10s.

But on our custom board, it can not be booted. We can't see any log in the terminal.

The type of eMMC is SDINBDG4-8G-XA on our custom board.

Do you mean even after waiting for 10s, you do not see boot logs like the EVM?

Have you confirmed if the eMMC backup boot is working when primary bootmode is anything except eMMC/SD like SPI.

Yes, no log output no matter how long we wait.
