@readmodifywrite could you please check if CONFIG_FREERTOS_TASK_FUNCTION_WRAPPER is enabled in sdkconfig?

[readmodifywrite]

Looks like it is not, and I cannot find an option in the menuconfig to enable it. Editing the sdkconfig file also didn't work, the changes are overwritten by the build.

[igrr]

This option depends on CONFIG_COMPILER_OPTIMIZATION_DEFAULT (https://github.com/espressif/esp-idf/blob/b65a37795f3c04d36f0a504a74e7e56950e3e3d9/components/freertos/Kconfig#L413), perhaps you have CONFIG_OPTIMIZATION_LEVEL_RELEASE enabled?

[readmodifywrite]

Ok, that does it, thanks! Could we get an update on the docs? They are otherwise extremely thorough and well put together, the rest of the setup was great.

[igrr]

Thanks for the feedback. Will keep the issue open to track the documentation update.
