Re: Need help to download firmware into ESP32

Anyone know if there is a way to download Arduino IDE code to ESP32 using an external USB-Serial converter connected to GPIO17(Rx1) and GPIO16(Tx1) ( instead of the default GPIO1(TX0) and GPIO3 (RX0) ) . I think the RX0 pin on my ESP32 is damaged and stuck high at 3.3v during the download phase.

Hi,

There is one way to change or update those UART settings using which you can change those RX and TX related changes.

Go to make menuconfig ---> Component config ---> ESP32-specific ---> UART for console output (Default: UART0, TX=GPIO1, RX=GPIO3) --->

So, you can change those settings as per your requirement but make sure that other GPIOs should be free which you will choose for that purpose.

Let me know if need any other help for that.

Ritesh Prajapati
