We've been developing several boards with the TI 2812 DSP for the past few months and have been having reliability problems with the Spectrum Digital XDS510 PP+ emulators that we bought bundled with Code Composer Studio and evaluation boards from TI. Two of the four are malfunctioning right now, and they're going back to Spectrum Digital for repair or replacement. I'm not saying that there is anything wrong with the emulators, the problems might well be our handling and our prototype boards. There are high voltages on some of the prototypes. I was just looking for any suggestions or experience anyone might offer. TI lists quite a few vendors of compatible JTAG debuggers, if anyone has used them. Also does anyone have any opinions or experience on the reliability of USB versus parallel port JTAGs? Thanks, -- Jack Klein Home: http://JK-Technology.Com

I don't know a lot about the 560 type debuggers, but there are several disadvantages that have been brought to my attention. First we need debuggers we can move from one computer to another, and at least half the time they need to work with laptops, no PCI slots. Second I do know that the 560 type is quite a bit more expensive. Third our TI tech rep tells me that the main advantages of the 560 type is based on chip architecture features that don't exist in the C2000 DSPs, so they provide no real gain for our 2812's. But I appreciate the reply. -- Jack Klein Home: http://JK-Technology.Com FAQs for comp.lang.c http://www.eskimo.com/~scs/C-faq/top.html comp.lang.c++ http://www.parashift.com/c++-faq-lite/ alt.comp.lang.learn.c-c++ http://www.contrib.andrew.cmu.edu/~ajo/docs/FAQ-acllc.html

Unless you HAVE to use a laptop I would not consider it. Generally it is a good idea to stay away from any JTAG emulators that uses the parallel port to connect. It is always slow and you will end up spending lots of time tweeking windows and BIOS settings to get things to work. The best option is an ethernet emulator, no special drivers requiered and allows you to set up your boards in a lab enviroment and debug remotly. I have not used a ethernet emulator with TI dsps but they always wins... The JTAG emulators that TI makes themself is a very safe way to go. CCS will work right out of the box and all new releases are well tested with them for obvious reasons. These are the good ols XDS510 (ISA based) and the new XDS560 (PCI based). The XDS510 is a very reliable workhorse and has good performance in spite of the ISA bus. I have used it alot and have never felt constraind by it when doing normal development. If you plan to stream massive amounts of data over RTDX it might be an issue but otherwise not. The real problem with it is that it is hard to find PCs with ISA slots nowdays. I have only used the XDS560 briefly, but it installed very easily and worked just great. PCI based and has a decicated 6202 DSP on it doing god know what. If you have a decent budget I'd get a XDS560, if money are tight I'd try to find a XDS510 on ebay (the going rate seems to be about $500 vs $5000 for a new XDS560). I have also used a PCI emulator from FleXDS, worked OK but a bit more work to install but not overly so. Performance in between the XDS510 and XDS560. /Regards, P�r Ligander
