Hi!   I'm using the C6416 DSK (Rev E) from SpectrumDigital, when CCS connects to the board I get the following error: "Error 0x800000A0/-2090 Fatal Error during Execution, Target Communication Device driver: Timeout on Emulator or Target Processor" Sometimes CCS starts up normally and i can use the board without any problem for some hours or even a day, sometimes I get the error after a few minutes. Only things that helps is disconnecting USB and power from the board and reconnecting it again. Another issue is, that if I connect the board to the PC, I can run the "6416 DSK Diagnostic Utility" exactly once without an error. The second time it stops at testing USB or emulator and only disconnect/reconnect helps :-( I tried this with the board in 720/600 MHz mode, with CCS v2.20 (from the package CD) and v2.21 (after installing the update from TI website)... always the same problem.   Has anyone the same problem/solved it/any ideas??   Andreas

Andreas, I have encountered exact similar problem and was stuck with it for 6 months or so. After all the observation and trying different methods I came to this conclusion ( I may b totally wrong) . In my case what I was doing was I was halting the execution of my code when GEL operations are being evaluated. Due to I used to get error messages. So the simple solution was to not halt the CPU when its evaluating GEL operation. Ok and to know whether GEL operation is being evaluated just check for G in a small circle icon in the status bar (at bottom ) of CCS it mite not be always there. I understand that this is just one of the situation and this solution applies to it .. but I am aware of other situation where the board on its own wud not like to communicate with CCS and I dont know how to take care of that. Hope this throws some light in right direction Tarang On Fri, 12 Nov 2004 12:16:41 +0100, Andreas Falter <> wrote: > > Hi! > > I'm using the C6416 DSK (Rev E) from SpectrumDigital, when CCS connects to > the board I get the following error: > "Error 0x800000A0/-2090 > Fatal Error during Execution, Target Communication > Device driver: Timeout on Emulator or Target Processor" > Sometimes CCS starts up normally and i can use the board without any problem > for some hours or even a day, sometimes I get the error after a few minutes. > Only things that helps is disconnecting USB and power from the board and > reconnecting it again. > Another issue is, that if I connect the board to the PC, I can run the "6416 > DSK Diagnostic Utility" exactly once without an error.

Thank you for your answer, Tarang. I'll have a look at that tommorow, perhaps it works for me, too. But it's strange, that the error occurs also when executing the diagnostic tool, sometimes directly at the first USB diagnostic, so I thought it is a problem with the USB driver. OK, maybe something on the board gets corrupted by halting the cpu while GEL operations, but this should be reseted with the power restart, shouldn't it? So I don't understand why after a reboot of the board there is the same error even before CCS has started completely ?! OK, I'll have another try tomorrow, last monday it worked fine the whole day :-) Bye Andreas -----Ursprüngliche Nachricht----- Von: Tarang Dadia [mailto:] Gesendet: Freitag, 12.
