LoadProhibited on fprintf in function set by esp_log_set_vprintf
Posted: Mon Oct 09, 2017 2:19 pm
I am trying to split ESP logging to both the UART and a File on Wear-level, however I am getting a "LoadProhibited" when I try to call fprintf on the FILE* in the function set by esp_log_set_vprintf. I don't see any hints in the backtrace on what I am doing wrong.
fprintf works perfectly when I am not calling it inside LogDuplicate.
Any help would be appreciated.
Backtrace:
