I am interfacing my ESP32 Pico with Tiva C launchpad using UART. Even though I can read data sent from Tiva C, I am unable to read the data, sent from ESP32 (receive queue is empty). Please help me understand if there's something wrong with my configuration. Attached code for ESP32.
Baud rate - 115200 bps, data bits - 8, stop bit - 1, parity - None
TX - IO9 (ESP), with RX - PB0 (Tiva)
RX - IO10 (ESP), with TX - PB1 (Tiva)
UART peripheral - UART1 (ESP and Tiva)

Re: ESP32 UART1 not sending data?
Suggest you connect a LA or scope to the lines, to see which of the two CPUs is the culprit.

Tried an echo test by interfacing ESP32 with FTDI chip, was able to run successfully. Seems it's an issue with the Tiva C board. ESP32 is working fine.
