I've got Luckfox Pico Plus board and it has a FLASH memory chip onboard. Besides it has SD-card slot. I burned image into SD card and put it into a slot then power on the board. I expected the image was loaded from SD card but it still boots from FLASH chip. I can't even see the SD card via internal Linux.
Could you tell me how to boot from SD card and how to mount SD card in internal Linux?
