uIEC/SD fo Dummies
Ok, I just got my uIEC/SD and a 2GB card. I put a few PRGs on the card. Now I have it hooked up to the VIC. I tried a few times to LOAD"$",(every device number from 8 to 16). All result in a brief flicker of the left LED and a ?DEVICE NOT PRESENT error.
Can anyone talk me through using this item?

Okay, that means the card reader worked. I was a little concerned that it wouldn't. I didn't get a chance to prep the card properly so it's showing as a 1GB card even though it's a 2GB so I would start by creating a single large partition and reformatting with FAT32. Then I'd go with Kweepa's advice and put a single program file on the card AND a single d64 disk image which contains the same program file and we'll begin experimenting from there.Jeff-20 wrote:I put a few PRGs on the card.
In the end it will be as if nothing ever happened.
But would uIEC get confused because the memory card is partitioned? There is a command @CP used to select partition. If Jeff is unsure how to repartition the card, he could try something like this:
OPEN1,10,15,"CP1":CLOSE1
Try CP2 etc if it still wouldn't find any directory. Actually I haven't tried this myself, so I don't know if it would be a solution.

Panasonic seems to have some software, as linked from the sd2iec wiki page:

I don't know how (well) it works though.
Edit: Err.. maybe it just formats memory cards, not creating partitions.

The Panasonic tool creates exactly one partition spanning the whole card and formats that - SD cards are not supposed to be partitioned in any other way or formatted without a partition according to the specs, although uIEC doesn't care and should handle whatever you throw at it.Edit: Err.. maybe it just formats memory cards, not creating partitions.
A ?DEVICE NOT PRESENT error indicates other problems though, uIEC should still respond even if it can't read the card at all or there is no card inserted. Just to make sure it isn't stuck in an infinite loop during initialisation, please try to power it up without a card and read the directory - if you hit the correct address (should be 10) you should get ?FILE NOT FOUND instead. If that doesn't work on any address playing around with the SD card is useless, the problem is somewhere else.
My VIC showed the same error when I tried to load programs or show a directory from my 1541 Ultimate, which is device 9. It had no problem reading from a device 8 1541-II disk drive. It turned out to be both VIA (6522) chips that were partly broken. Once I replaced them the VIC could load from either drive.

I got mine this past weekend, but alas, I am still waiting for SD and a USB reader to arrive. I am hopeful this is even better than using the Linux OpenCBM driver to write to a real 1581 diskette -- which works like a charm, BTW.
Er, okay, just WHERE do you find useful commands like that? Is there web site / page that I am not seeing?

Any technology distinguishable from magic is insufficiently advanced.

The best and currently only (?) place for documentation:

Check out "sd2iec Read Me" since the uIEC/SD comes with sd2iec firmware.
