  • Sometimes, when turning on the F256K/Jr, I get greeted with this screen, from which nothing can happen. How do you resolve this and why does this happen?

  • Every time you are powering off and on your unit, the FPGA needs to reprogram itself and that takes time (i.e. Not Instantaneous). It's possible to have faulty loading because the power supply is not quite stable; the RTC that generates the reset is not aligned with the rest of the system. If you are doing a quick on and off, the capacitors are not empty enough to create a rising power rail so the reset can do its things. Unfortunately those are not ASICs, so nothing is instantaneous.
