ESP-IDF 4.1 Error: mcpwm_capture_signal_get_edge crashes

[ttlappalainen]

I have also similar crashing problem.

I use PlatformIO Espressif 32 version 3.2.0, which has ESP-IDF 4.2. When I call mcpwm_capture_signal_get_value in my IRS routine, it crashes, if ISR happens same time while saving settings to LittleFS.

I wonder are these routines like mcpwm_capture_signal_get_value loaded to IRAM? At least they do not have IRAM_ATTR marking.
