ESP32-WROOM-32 Flash update question
Posted: Fri Aug 31, 2018 9:43 am
Could we do the ESP32 firmware update through HSPI bus from our Master with ESP32 being a slave in our system ?
There is HSPI driver for slave mode in the esp-idf.
And there is a OTA example.
I think it's feasible, you can try to combine those two thing to realise this function.
