Hi @Harbal,

thanks for your response. To be honest, I'm afraid I don't really understand what you mean by your hint. How could the USB config keep the ESP32 in download mode? Could you provide me a clue where I have to look at?

Cheers

Hi all,

not quite sure whether this is the right place for the topic but I'll try my luck.

environment is
IDF 5.2.5
Debian 12
ESP32-S3-WROOM-1 (N16R2) module on own HW

Due to a tricky issue we've observed in our target device I began to try the JTAG debugging capabilities of the ESP32S3 what ...

Update: I was able to find a solution for this rather generic problem.

The root cause was a circular dependency between the prebuilt library and the application code: The library depends on the application to implement "prebuilt_ext_func()" while the application depends on the library to implement ...

As my demo only was a modification of the official IDF "import_prebuilt" example I expected this construct being correct. Nevertheless, I tried to extract the 'prebuilt' subproject from the example as you proposed. But the result is exactly the same .

Hi SparkyNZ,

thanks for your thoughts. I intentionally avoided to mix up the example with C++ files as I'm aware of the name mangling pitfall in that case. To be honest, my real application uses C++. But as the simplified, plain C example revealed it's not caused by that topic.

Cheers

I have a curious linker problem with an "extern" declared function in a prebuilt library which I don't really understand.

Short background: I got a prebuilt static library (.a) that requires some functions to be defined by the application to result in an executable. Let's call such a function ...

Hi arex-ebee!
Have you found a workaround for this? I've followed the github issue you posted but it seems it has not been fixed.
Thanks


Hi AlSantana,

you're damn right, the issue actually seems orphaned :( . In my project the SoC temperature is just a small peace of the overall health ...

Thanks for that hint. I guess you actually mean https://github.com/espressif/esp-idf/issues/8485, right?

Hi XiangH,

thanks for your reply.


I had this problem too, but I was developing with the latest ARDUINO framework,


When you say you "had" this problem does it mean you found a solution? As the Arduino framework is "just" a further abstraction layer it may be worth if you could share your ...

Hi folks,

Setup:
Module: ESP32-S3 WROOM-1
Dev-Board: ESP32-S3-DevKitC-1 v1.6
IDF: master (up to commit 0a64094a60194db3a4bf0ce87ad180999d538c49)
Host: Ubuntu 20.04

I'm currently evaluating the ESP32-S3 on WROOM board (ESP32-S3-DevKitC-1 v1.6). My use case requires the ADC to continuously convert ...
