I came across issue of UART_BUFFER_FULL while soft reboot. This issue is not seen in hard reset (unplug cable).
I have tried option of Uart flush, reseting queue, I still see this problem. I also tried adding delay at the beginning of boot.
Do you have suggestion, where to look into or any documentation link. Thanks in advance.

ESP32_WROOM - UART_BUFFER_FULL soft reset issue
Re: ESP32_WROOM - UART_BUFFER_FULL soft reset issue
This problem is mostly related to when you communicated over UART with external device being master and ESP being slave.
The fix is simple you need to reset master statemachine if your slave communicating over UART. or Master to provide interface to reset the statemachine at the time of boot up.. otherwise you never be able to sync communication
