Description

ESP32_S3_ZERO failed to boot after flashing ESP32_S3 firmware. it keeps rebooting with boot failure message "Guru Meditation Error: Core 0 panic'ed (LoadProhibited). Exception was unhandled."

After read the boot log, I found a possible reason: the boot loader reports 8MB spi flash, but there's actual 4MB flash on the board.

How to reproduce

Flash ESP32_S3_ZERO with following commands:

nanoff --update --serialport COM12 --target ESP32_S3 --masserase

command output:
