APLL is occupied when using i2s in esp-idf 5.0
Hi, i'm trying to update my project from esp-idf 4.3 to esp-idf 5.0 and i'm struggling with the i2s drivers and more precisely with the APLL. In 4.3 we had to use apll to avoid clicks in audio signal. I read the documentation and it seems that the APLL can be used by other drivers and we need to ens...

Re: SHA256 of .bin doesn't match get_sha256_of_partition()
Is there a way to reproduce the digest given by bootloader_common_get_sha256_of_partition() at compile time or after compile time ?

SHA256 of .bin doesn't match get_sha256_of_partition()
Hey I'm currently working on the OTA side of my project. I have different hardware targets and my build script generates different .bin for each targets. When a new firmware is released, the .bin goes to a server wich provides the files for OTA. Of course I wanted to automate the build / release pro...

FreeRTOS heap allocation at compile time.
I'm monitoring my heap usage with esp_get_free_heap_size() during the program's lifetime. I have noticed a strange behavior (at least for my level of comprehension of the FreeRTOS). Let's assume these simple lines of code : if ( 1 > 2) { xTaskCreate(&myTask); } Obviously the condition will never be ...

ESP32 - interrupt handling issue.
Hi, I'm quite new to C and the embedded world, i'm trying to do an interrupt on GPIO36 and GPIO39 (these pins can't be changed). I hardware pull high both of the pins with a 10k Resistance. I used the ESP-IDF example : Here is my initialisation : #define RESET_BUTTON_0 GPIO_NUM_36 #define RESET_BUTT...
