UART flash download procedure

Postby falling_stone » Fri Nov 10, 2017 1:06 am

Hi,
I need to write ESP32 flash in production from host MCU through UART.
Can Anyone please provide me a step by step explanation or maybe some SW example of FLASH writing procedure in UART download mode?
Thank You and Best Regards,
F.S.
