Hi,

Is there a way of flashing SPI ROM by booting the device in UART mode?

Thanks,

Hi John,

Thanks for your post.

Yes, it is possible to flash the boot code to SPI through SPI flash writer, but the boot pin configuration needs to be changed from SPI flash mode to JTAG emulation mode. Without changing the boot pin configuration, still you can update the boot code to SPI flash through JTAG but with other boot media like UART or others, you should create a provision to change the boot switches and in this case, you need to remove the gel file while you try to re-connect the device using a J-TAG.

Please refer the below E2E threads:

Please refer the below wiki to check the procedure for boot and flash loading utility:

Note: Please generate the boot binary format via AISgen utility and then flash it to SPI.

Thanks & regards,
