Ummm... well... I seem to have the SD card fully functional now.

I am fairly mystified by this. I know what I did wrong in the code, but it really doesn't explain what I was seeing with my logic probe. I intend to do some voltage checking when I have a bit more time.

Regardless, I think we can basically check one more subsystem off as tested! In fact, the SD card driver is now fully functional and the S2I firmware can use either the IDE device or the SD Card device for storage. I will post updated firmware in the next few days.

Also, I quickly checked the config latches. They absolutely work, but noticed that I need to read the port twice if I change the shorting blocks without a power cycle. On the first port read after moving the shorting blocks, I get the previous value. On the second read, I get the updated value. Is that expected???

Thanks,

Wayne
