10:28 PM Feature #62: Store settings in spi flash: Tried with 9f since I'm not sure ab is supported. Same result.
Got the scope on it and checked that the commands a... foft
09:11 PM Feature #62: Store settings in spi flash: I found out I'd connected the hardware (in the vhdl) wrong, so no dice.
Reconnected what I thought was correctly, ... foft
08:20 PM Feature #62: Store settings in spi flash: Think I have the hardware side connected, trying to talk to it now via firmware. Fingers crossed! foft

10:13 PM Feature #62: Store settings in spi flash: On some cyclones the active serial pins can be directly used as IO. I tried that on here (cyclone v) but it didn't wo... foft

09:24 AM Feature #62 (Closed): Store settings in spi flash: Read/write settings from the flash chip, with override from sd.
Want to check this works before new boards. foft

09:21 PM v18: I've been trying out some other parts of the hardware in advance of the new boards. The clock generator and the i2c v... foft
