Hi, I hope you are well.

Does Piccolo support FreeRTOS?

charlie-bluespec commented 2 years ago

Hi, hope you are well too. Yes, Piccolo does support FreeRTOS. We've run basic FreeRTOS blinky tests on a few Piccolo configurations. That doesn't constitue broad testing across Picoolo configurations and FreeRTOS modules, but we don't expect any problems. If you do run into any issues with FreeRTOS, let us know and we will address them.

Thank you very much for your answer. I will try to run some blink tests as well. Also, are the blink tests you run available?

What simulator do you use? We have it running in Questa and should be able to provide something in reasonable time for Verilator.

I am using Vivado, Verilator and GTK Wave.
