Jtag flash programmer

Started by Simon Lightbody August 21, 2002
Does anyone have any experience with the command line JTAG flash programming
app that is provided in SDK2.5 for the DSP568xx? I'm having a problem
running it (in NT4.0). It gives me a Dr. Watson even though I ran the
userport.exe first. Thanks for the help.



After a bit of work, I did get it running in Windows 95.  It seems as though the FLASH807.cfg file is incompatible with the application speed test mode.  The application apparently expects the first configuration line to specify the first Program flash area of memory. rather than the Boot Flash memory.
 
Once I changed the configuration file I did get it to program the 805EVM board, the 807EVM board, and our 807 specific custom board/custom Jtag interface.
 
The documentation calls for installing the "userport" driver into an NT based system (NT4.0, W2K, or XP), so that the "dos app" can access the parallel port directly without going through a protected mode LPT driver.  Presumably this is done to speed the process up, and bypass the protection against running hardware from an application.
 
I do expect to test that environment next, and will post the results unless someone has done it already???

I did successfully run the JTAG Flash Programmer from NT, W2K, and XP.  On NT I got a couple of exceptions, but restarted UserPort via the UserPort.EXE routine.  I did have a parallel port Zip drive previously connected, which I disconnected then hooked up the cable.
 
When powering up, after installing UserPort.sys, userPort.sys did not automatically start running.  I got an Event logged during system startup, so I did have to start it by hand (using "devices control panel").  After I had started it by hand, using the "devices" control panel, I got the exceptions the first time couple of times II ran the Jtag programmer application.  After restarting it via the UserPort.exe routine, the jtag programming app worked fine.
 
I had no problems in Windows 2000, or XP.
