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

readmodifywrite commented 3 years ago

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 commented 3 years ago

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 commented 3 years ago

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 commented 3 years ago

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