Booting from Flash

The kernel needs to have the right drivers enabled, either configured in before it is built, or loaded at runtime. The previous message suggests that “sudo modprobe mtdblock” should work for Ubuntu 22.04.

Hi senior,

If boot from SPI flash,the CHIPIDSEL is ON or OFF?

Don’t touch it, only touch the four MSEL switches

thank you :heart_hands: :heart_hands: :heart_hands:
