Hi @tnt We are looking ahead at a hardware configuration that we could deploy to all MPW-2 where they could successfully run a diagnostic to characterize their part and then use the output to successfully program IO. we looked at the setup you have with ICEbreaker, but I have concerns about availability as well as if that is a good option for non-expert users. Today we discussed the possibility of updating the caravel board to mount onto a Nucleo 64 or 144 board. The idea would be to have a similar capability to emulate flash, tune voltage, and monitor/drive gpio signals on the chip under test. The main board could then still be used independently for test evaluation of the users project. Wanted to see your thoughts on both the ICEbreaker and Nucleo options, or if you have another idea.
