A JTAG bit-banger is not hard to write (I've written at least two of them), and a lot smaller than an xsvf file player. The one I use routinely now takes a small fraction of the 8K program space of an 8051 derivative (CY7C68013). The input file is the straight bitfile. Granted it will run a little slower than SPI, because unless you're exceptionally lucky it won't be hardware accelerated. It would be fun to take a crack at the bit speed limit on that 96 MHz processor, though. - Larry _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
