EVM not working on parallel port
My DSP56311EVM is nicely working on my old desktop PC, P3 with win2k.
I installed SUITE56 on the laptop (P4, winxp), and the board seems to be not detected.
Any idea of what's going wrong?
differently on different days. My older tower system (AMD Duron)
running 2K works very consistently, my two new tower systems (both P4s)
running XP work 90%+ of the time (seems that a few of the Windows
updates affect Suite56 drivers) and my newest laptop (P4) running XP
will only connect to an EVM using an external command converter (even
then 2 of my 5 PPCCs won't work with it) or if I connect directly to
the EVM through the docking station. It seems to be an issue with the
parallel port drive capability of the laptop. If I look at the signals
from the laptop vs. those from the dock the amplitudes are very
different. I think a shorter cable might help, but so far the best luck
I've had is with an external command converter (PPCC). Of course
another person I know with the exact same laptop I have can communicate
directly with an EVM without using the dock...
