Flash new application in ESP32 using another microcontroller
Posted: Sat Feb 22, 2020 11:05 pm
Hello,
I'm designing a custom board with an esp32 Soc on it and I want to be able to update the esp32 firmware using a host microcontroller available in the board.
I can't find any examples of this so I'm wondering what pins should I connect to my host microcontroller!
I know that at least pins CHIP_PU(9) and IO(23) and maybe SPI or UART pins ?
Is there any example out there to use as reference ? otherwise any help would be very useful for me
Thank you.
