Re: [Xc3sprog-users] indirect spi programming issues

[Charlie M. <cjm...@gm...>]

I managed to fix both issues fairly easily. The first was caused by a space
between -I and the bitfile. The second was a simple matter of adding a
couple of lines to the progalgspiflash.cpp. Diff below.

Thanks,
Charlie
