abort (at locks.c:81) while create mutex during i2c implement
Posted: Thu May 09, 2019 8:37 am
while we test basic i2c functions, esp32 reset around every 7000 loops. back trace point to
in locks.c
here is the code, very basic i2c functions:
here is the back trace
We 've also report the issue https://github.com/espressif/esp-idf/issues/3444
Have anyone got good suggestions?
Code: Select all
xSemaphoreHandle new_sem = xQueueCreateMutex(mutex_type);
if (!new_sem) {
abort(); /* No more semaphores available or OOM */
}in locks.c
here is the code, very basic i2c functions:
