02/21/2023, 7:47 AMAny one can point me to an update documentation of how the I/O works (the readthedocs seems not to be up to date)?, I'm trying to create some kind of channel to communicate with the harness for fast testing. The UART TX seems to work without issues but I didn't manage to receive nothing from the RX channel, so I'm trying to use the IO as a way to communicate with caravel, but I'm having issues to read from caravel

02/21/2023, 4:33 PMDidn't have time to test that today, I will test that tomorrow morning and I will provide feedback on that. Still I need that working for radiation testing

02/22/2023, 9:09 AMSo regarding the RX in caravel @Tim Edwards. What I found is that the register no always reruns to 0xFF, and reading is somewhat random, some times receives something, some times does not work at all. So I will like to more people test this feature. I will test it in more chips in the future for sure. (For the record the chip is at 1.5V, I will try latter to 1.6V to see if is any difference)

04/03/2023, 6:35 AM@Ivan Rodriguez we're trying to compile feedbacks from the MPW-2 bring-ups, do you have a picture and a quote/testimonial that you'd be ok to share?

04/03/2023, 7:09 AMSure, I will prepare something.What kind of testimony do you need? Like my experience doing the bring up?
