Configure U0RXD as Uart Tx for debugging

Postby Jonas A » Fri May 07, 2021 9:22 am

Hello,

I use an ESP32 WROVER-E and want to configure GPIO3/U0RXD pin as UART0 Tx , is that possible?
I've attached my "Common ESP-related" config where i set "UART TX" to 3.

I've tested this and measured that pin but it doesn't toggle so no data is sent although I sen debug data using esp_log_write function.
It works good if I use default setting and use GPIO1 as UART0 Tx and GPIO3 as UART0 Rx.

BR,
Jonas
