Just a thought, and I don't know if it applies to your set of IDF/compiler, but are you using PSRAM? Does it still happen if you disable it?

Deployment to GitHub master branch is currently stalled because of an internal CI problem Sorry for hijacking the thread, but is there a guesstimate on when that'll be up and running again? Gibson - just a few words re. my experience working from the master branch. I've done that since pre v2 I thi...

I favor CLion for the IDE. It's easy to setup and works fine with IDF. I've also used VSCode and it works, but I find it a bit messy setting up. Is there an editor/toolchain combination that let's me easily jump to the outside code like "driver/spi_slave.h" or go to the defintion of functions like t...

Angus, That's the ting - it's not any longer. I've spent the weekend redoing my build system so that it follows IDF's component-based variant when building for the ESP (too much hassle using IDF as a lib when it is removed two steps from the main app). The only thing I'm doing differently is that I ...

v4.0-dev-1443-g39f090a4f
tensa-esp32-elf-gcc (crosstool-NG esp32-2019r1) 8.2.0

CMake output attached.

I do have WPA_MBEDTLS_CRYPTO, which presumably enables USE_MBEDTLS_CRYPTO

Disabling WPA_MBEDTLS_CRYPTO allows the project to compile, but that's not what I want.

I'm following the "rename main" component instructions in the documentation , but have gotten stuck on the following errors: : && /home/permal/.espressif/tools/xtensa-esp32-elf/esp32-2019r1-8.2.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-g++ -mlongcalls -Wno-frame-address -nostdlib CMakeFiles/smooth_tes...

Thanks for the reply, Angus.

I had a look at esp32.project.ld.in ....it's like programming language in and of itself! I'll stick to -mtext-section-literals for now.

As to why -mlongcalls doesn't propagate I don't know, will have to investigate later.

@ESP_Angus They are now (and it is working), since I added the compiler flags as per the earlier post. Are these settings enabled by default in ESP-IDF? If so they are probably not propagated to my code since I build IDF as a library and link against it.

Here's the dump as am attached file. 6.5M so a bit too much to post as text.
