Byron Lathi	335f877d66	Run simulation with verilog sd emulator ... This also slowed the cpu clock down, we should speed it up again	2024-03-14 08:17:05 -07:00
Byron Lathi	455814ec14	Update sd controller and test code	2024-03-12 18:20:51 -07:00
Byron Lathi	61f6e53327	Updates based on fpga test ... 1. in SD mode, CMD0 does not have a response, so we specifically ignore it. 2. The penable signal was messed up, although it looks like this doesn't matter anyway 3. The SD clock should be out of phase from the data signal by 180 degrees, so that we get max hold time	2024-03-10 22:09:55 -07:00
