gptimer config error on .clk_src
Posted: Tue Dec 20, 2022 1:25 pm
Hi, I've update my code from ESP-IDF 4.3 to 5.0 and one of the thigs that changed was the general purpose timer, I'm trying to use the timer on a custom project, it builds and flash but when I turn on the board I get this error on the monitor.
this is the code for the init_timer0:
I tried to use the example code from the GPTIMER and it works flawlessly.
