[T2080] : Error porting u-boot to Flash

Arathi · ‎11-05-2023

Hi NXP Support Team,

I am having a T2080 processor card and trying to boot from eSPI flash.

Configured the board to boot from Hardcoded boot mode and through Code warrior tool target tasks flash programmer window programmed and verified my RCW and u-boot contents into flash successfully.

Next Configured the board to boot from eSPI mode and found uboot to be getting hang. Below are the prints obtained on the serial terminal.

Hi Arathi,

How did you configure the T2080 custom board to boot from eSPI mode and uart for the u-boot prints??

is there any preferred offset locations to load the RCW and u-boot files in the flash?

And what u-boot file you used to load into the spi flash....can you please tell the procedure you followed..

Thank you

Regards,
Priya
