Description

I'm using MicroPython esp32spiram-20220117-v1.18 successfully since some time and now wanted to upgrade to 1.19.1 or even 1.20.0. I tried to flash esp32spiram-20220618-v1.19.1.bin (with and without SPIRAM) and esp32spiram-20230426-v1.20.0.bin (with and without SPIRAM) but with both firmware versions the device is no longer booting or even responding to mpremote REPL commands.

Steps to reproduce

Expected

Log flashing 1.18 and doing simple REPL interaction
