Tested this with small text file named "fake.d1_mini.bin" wth 0xE9 as first byte - did report no error on update, but crashed on reboot. | |

| Jan 1, 2021 at 0:35 | comment | added | Sim Son | You could just try what happens if you perform such an "illegal" update. My guess is that booting an image intended for the other MCU would fail and be marked as corrupted firmware image. If esp8266 and esp32 have different flash sizes I would expect the bootloader to recognize the faulty firmware images | |
