Tool/software:
Trying to load patch bundle from MCU (ESP32-S2) over I2C (400kHz), according to docs, but for some reason I get !CMD. I have tried loops with different delays, but nothing seem to work even if all commands are correct. Reading and writing seems to work correctly. I have tried two different chips, same result.
I also have a question about IRQ_Event. In the Register Overview, register 14h, Ready for Patch is bit 81, but in forum I have seen to look for bit 1, which according to docs is PD Hardreset? When I read register 14h I get 2, i.e. bit 1, i.e. PD Hardreset from my understanding?
Attaching log below.
