CANBus does not work at all in C4.1-beta2 in release mode due to numerous assert statements having been changed such as this one:

Code: Select all

      assert(can_hal_start(&can_context, p_can_obj->mode));

In V4.0 this was:

Code: Select all

    esp_err_t err = can_enter_reset_mode(); //Should already be in bus-off mode, set again to make sure
    assert(err == ESP_OK);

There are about 8 similar problems in this file.

Hi dedvalson,

Thanks for reporting this, and sorry for the inconvenience. We're going to attempt to fix this before the v4.1 final release (we're about to release v4.1-rc, unfortunately it's not fixed there).

In the meantime a possible workaround is to configure "silent asserts" - assertions failures still abort, but no message is logged and less binary size increase.

I've edited the topic to include our internal tracking ID.
