Hi.
I have a project where I use the PIO to capture raw states from the GPIOs. It is a project that has been running for some years on Picos without problems and now I wanted to port it to the new Pico 2 to have that extra memory as it would benefit a ton my project.
I don't have any pull down/up configured (in fact I have tried to force them to disabled) and it seems that the PIO triggers the lock. Whenever a high level is input to any pin the pin starts outputing 2.7v and there is no way to get it back to normal.
I cannot enable/disable the GPIO's on each capture as the PIO is capturing data at 100Mhz so I'm starting to think the Pico 2 is basically dead for my project and I have bought a good ammount of these...
Do anyone know a workaround? Or I just have thrown 100€ to the trash?
