EVM not working on parallel port | Freescale DSPs

Technical discussions about Freescale (Motorola) DSPs (including the DSP56000, DSP56300, DSP56600, 56800 DSPs).

It's a realatively common problem. I have 4 computers each works 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... -- dB --- gusflit@gusf... wrote: > Hi! > > 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? > > Thanks! __________________________________ Start your day with Yahoo! - Make it your home page! http://www.yahoo.com/r/hs
