I try to compile after enabling app level tracing over uart in menuconfig but i get the following compilation error. Note that the build works fine if I select app level tracing target to be JTAG!

My settings are:
Data Destination 1 (None) --->
Data Destination 2 (UART1) --->
(33) UART TX on GPIO#
(34) UART RX on GPIO#
(1000000) UART baud rate
(128) UART RX ring buffer size
(4096) UART TX ring buffer size
(128) UART TX message size
(1) UART Task Priority
(-1) Timeout for flushing last trace data to host on panic
(0) Threshold for flushing last trace data to host on panic
FreeRTOS SystemView Tracing --->

Inside FreeRTOS SystemView Tracing:
[*] SystemView Tracing Enable
SystemView destination (Data destination UART) --->
CPU to trace (CPU0) --->
Timer to use as timestamp source (General Purpose Timer (Timer Group)) --->
(16) Maximum supported tasks
(500) Trace buffer wait timeout
[*] Trace Buffer Overflow Event
[*] ISR Enter Event
[*] ISR Exit Event
[*] ISR Exit to Scheduler Event
[*] Task Start Execution Event
[*] Task Stop Execution Event
[*] Task Start Ready State Event
[*] Task Stop Ready State Event
[*] Task Create Event
[*] Task Terminate Event
[*] System Idle Event
[*] Timer Enter Event
[*] Timer Exit Event

This was fixed on master branch in https://github.com/espressif/esp-idf/co ... d28630f6ee, we will backport the fix to the next v5.1.1 bugfix release as well!

I updated the toolchain to latest and now the project builds fine, however now the CPU crashes why accessing filesystem with the following dump:
