I finally have a new development system. It should speed things up once I have everything configured <G>. NoICE/ICC430 work great with the included parallel port. But I need to also JTAG a C5416 DSP on the same machine, so I added a PCI parallel port card. It is setup as LPT2 in its hardware config dialog, but neither NoICE or Code Composer Studio seem to want to recognize that the port is there. This is the first time I've used a PCI parallel port card (this is one from Kouwell, IOFLEX-1NP) so I may be missing something. In its hardware resources tab it says its using memory ranges 0xDED0-DED7 and 0xDED8-DEDF NoICE only allows you to select LPT1,2,3 so I can't enter the IO ports directly (and don't even know if that will work). I tried that in Code Composer and it still didn't recognize the XDS510PP. Does anyone have any ideas? Thanks, Brian -- ----------------- Brian C.

Brian, Wouldn't it be easier just to use a second PC for debugging that second DSP? The time you've been wasting on getting that second parallel port working would have probably paid for a new PC. Besides, and I might be wrong here, you can not have more than one instance of CCS working on the same PC. You can only debug more than one DSP concurrently within a single CCS session if these DSPs are within the same JTAG chain. Roland -----Original Message----- From: Brian C.

Things like CCS, Xilinx tools, etc are looking for 278h as base address, but unfortunately Microsoft has not allowed "legacy bus access" to 0x278 to work. They did allow 0x378 to work to prevent a mutiny. That means all software has to be **modified** to work correctly on Win2k with LPT2, specifically, to use API calls to a PCI driver to talk to LPT2. Of course, engineering tool software does not get modified that fast so it becomes an issue. Linux has taught Microsoft the hard way that yes, actually developers are important and forcing them to rework their software every new OS release actually does translate into lost revenue. M$ knew developers were important back in the early days, but people like Ballmer forgot the lesson. "Always dance with the one who brought you". -Jeff |
