Hi Team:

The Debug UART connected to my Host PC the Station P2 fails to start the kernel - "Starting kernel ..." - always dropping back to the => prompt.
This happens on all the images from https://en.t-firefly.com/doc/download/page/id/94.html

Refer to this description: https://wiki.t-firefly.com/en/RO ... are_with_flash.html

First use `EraseAll` to erase emmc and nor flash respectively, and then flash the firmware to emmc.

Thanks for the reply. I have become an expert on flashing the Station P2 in the last week.
I have been building a number of images - as my goal is to have mainline kernel and mainline u-boot.

The issue is that if the  debug UART is connected, the boot process stops at the =>

Is there something that the Firefly BSP u-boot is doing wrong? Or is there a settings that needs to be changed in the uboot environment? below is the detail of the u-boot (this is the build from the default: rk356x_linux_release_20210511.)
