Hello, all...
Has anybody gotten xc3sprog to work with the raggedstone board and its included parallel programming cable?
I had to add an entry to devlist.txt for the configuration PROM (xc3sprog gets upset if it sees any unrecognized devices on the chain, even if they're not the one being programmed). After doing that, I'm able to program the S3 directly like this:
./xc3sprog pci_7seg.bit 1
The board's 7-segment LEDs go blank for a while and then come back on. Here's the kicker: the board is currently running the "default" bitstream that the board ships with, which counts down in hexadecimal. After the LEDs go dark, they come back *at the same counter position they were at before programming* and continue counting down.
So, apparently the device is not only not getting programmed, but it isn't even getting reset. Yet the LEDs go dark and xc3sprog reports no errors.
Weird.
Any advice?
