  Hello. On my Luckfox Pico Pro/Max, SPI_NAND was replaced with SPI_NOR.
  I would like to flash it by changing the configuration. As a result, the board is always in Maskrom and does not start the firmware.
  
  I assembled it using the following configuration:
  

  Code: Select all

  #!/bin/bash
