taskENTER_CRITICAL Guru meditation error StoreProhibited

Postby nicolasmm » Thu Sep 05, 2019 7:03 pm

Hello,
I am using xEventGroups in a task, waiting for events to store some data in the sd card. But I keep having the same issue which happens after two to three hours of running the program, the output also tells me the error comes from xEventGroupWaitBits and other times says it si form xEventGroupSetBits.

I am currently using the latest version of the ESP-IDF in Ubuntu Linux, however, I have already tried the stable version in a failed attempt to solve the issue.

This is the line of code, for calling xEventGroupWaitBits, I have tryed both portMAX_DELAY and changing the delay but it keeps failing. This code is executing approximately three times every second when the delay is larger than the events:

Code: Select all

 EventBits_t mask_flags = BIT(0) | BIT(1);
EventBits_t flags = xEventGroupWaitBits(sis.flags_sd, mask_flags, pdTRUE, pdFALSE, portMAX_DELAY /* pdMS_TO_TICKS(1000) */);
This is the output that I get in the latest version:

Code: Select all

Rebooting...
This is the output I get in the stable version, using the command: "make monitor >&1 | tee log.txt" to store the log, seeing the addres in backtrace with gdb, guide me to the same methods shown above:

Hard to say, specifically without source code, but it looks like something is overwriting a pointer. Look at EXECVADDR in both examples; there should be an address (0x3Fxxxxxx ) in there, but there seems to be data in there. Can you try enabling heap debugging / canaries, see if that turns up something?
