[Xc3sprog-users] xc3sprog support for FreeBSD and the Spartan-3 Board 200K

[Grzegorz B. <grz...@gm...>]

xc3sprog works, with FreeBSD 8 and the Spartan-3 Board 200K from
Digilent,  when this source code (in ioparport.cpp):

if ((status & PCIII_TDO_MASK) && (!(data & PCIII_PROG_EN_N))) {
        fprintf(stderr,"Missing power for Parallel Cable III\n");
        return NO_CABLE;

is commented out.

Could you please elaborate why this doesn't work on FreeBSD and your board? 
The check "works for me (R)" on linux and windows...

With those particular lines, I'm getting this error :

darkstar# ./xc3sprog -d /dev/ppi0 -j -v
Release $Rev: 426 $
Free software: If you contribute nothing, expect nothing!
Please provide feedback on success/failure/enhancement requests!
Check Sourceforge SVN for updates!
Missing power for Parallel Cable III
Could not open parallel port /dev/ppi0

without, it looks like this :

darkstar# ./xc3sprog -d /dev/ppi0 -j -v
Release $Rev: 426 $

There is one interesting issue: using only once the software free from
the "Missing power for Parallel Cable III" code block causes  the
original one (without any modifications) to work correctly.

This happens because code does not want to run when cable is not
connected to a device, or the device is not powered on.
Reading parallel port might look different in different OS - so this
could be related to some ioctl reading parallel port control lines?
Where is the "power detect" line located - at data lines or control
lines?

Maybe the first invocation of the program sets the control register of
the parallel port and the second reads the value..? What happens if
the port is being read twice (two read functions before to detect
power?

Regads,
Tomek
