Hi, I am not suspecting stack overflow, it’s a semaphore leak for the Tx buffer descriptors. Once all of the semaphores are gone, my application is still running as it should. The light’s blinking, DAC and ADC are being read/written to, and I’m even processing UDP packets. FreeRTOS goes through the whole motion of sending them back, they just never make it out.
There are a couple people actively responding on this other post though.
