DM6446 - Possible to set boot mode via UART?

Florian Denk99

Hello,

I have a board with a DaVinci DM6446 on it. It is not an EMV board such that I could set the boot mode via hardware switches.

Unfortunately I flashed a wrong ubl and u-boot binary to the NAND over UART such that the device now always tries to boot from NAND and fails. (I'm watching the output via UART in a terminal on my PC)

Is it possible to switch the boot mode via UART back to the UART boot mode so that I get the BOOTME messages and can flash the right bootloader binaries or am I stuck in this situation?


Thanks a lot!

Best regards,

Flo
