Please remind me prior to the QL meeting so I bring the equipment and FPGA data. As I wrote at several occasions, it turned out to make a difference on which operating system I had synthesized FPGA version 1.05. If synthesized under Windows 10, there was a stability problem that Martyn could reproduce. If synthesized under Windows XP, everything should be allright. Unfortunately, I never suspected such a problem with the FPGA toolchain, and it is now not traceable. Very unlucky. In any case, the fast SD card speed option of SMSQ/E is not an officially permitted way to access the cards. It should never ever be SMSQ/E default! It is a purely experimental feature used at own risk. I have warned about it all along. Also I'm not aware of an "auto-slow" feature. If SMSQ/E is configured to "fast", and for some reason there is a timing problem, card access will fail. A save feature to use is 16 bit access to SD cards introduced in FPGA version 1.02 and higher. SMSQ/E automatically detects this. Dilwyn Jones via Ql-Users wrote: > Mind you, my Q68 has never been able to run Jan's Minerva port either. If the latest Minerva and/or returning to FPGA version 1.02 does not help, I would suspect an actual hardware problem and your Q68 should be replaced.
