No. You specifically need a *dummy function* (or symbol) to declare as undefined. It works like this. - C compiler compiles all the objects - Linker tries to recursively resolve all symbols (=functions and variable names that are used between functions). It starts with the assumption that there are...

See the docs for that. Oh, I tried "target_link_libraries" but still failing... I can't understand why :( Let me explain better my project. My project is created using IDF 4.0 and use various custom modules created by me. Module for network, another module for NVS, RTC, webpage and etc. [firmware_n...

Does the dummy function plus -u [dummy-functionname] trick not work?

No, my question is how to add this flag to my custom component using CMake and not .mk. I tried to put this flag in .mk of main folder but when execute, CPU still calling the weak function.

Gotcha, then you have that issue. An option to fix this is to declare a symbol in this file, for instance by creating a dummy function: void ld_include_stackoverflowhandler_file_dummy_function() { //dummy } and then in the component.mk file declaring this dummy function as an unresolved symbol: COM...

Not sure if that's possible... if I recall my FreeRTOS internals correctly, queues have things like pointers to other FreeRTOS structures inside. Even if you find a way to simply blindly restore the memory used, those pointers may not be valid after you've restarted your program. Thanks Sprite! Im ...

Any one can help me? I need queue inside rtc_ram (NOINIT) to create temp buffers

Hello Guys! How can I use FreeRTOS Queue inside __NOINIT section? Im building ring buffer with Queue and want to keep values after software restart, but how to tell to 'xQueueCreate()' to not "reinit" or not "fill with zeros"? Just put __NOINIT_ATTR QueueHandle_t queue; not work (maybe because queue...

anyone?

Hello! Where can I change the max number of packets queued by mqtt lib? When network is OFF, esp32 keep sending data (qos 2) and when network comes back active, esp32 send only the last 3 packets, why? I changed .buffer_size and .out_buffer_size of esp_mqtt_client_config_t but still not working. IDF...

Hi,

In theory you can, but I'm not sure if it's the best thing to do. If you do so, maybe you can have issues in terms of RAM usage (RTC memory space).

How can I do this? Where I can change to compile C++?
