Info on Codewarrior USB Tap

Started by hgid...@instantel.com September 15, 2005
Hello:

I am looking for a connection to a Freescale 56858 that will work with Codewarriors debugger. Currently we are talking to the DSP56858EVM through its parallel port interface and would like faster download times. Eventually we will need to talk to our own board. Thanks.



Hi all,

Im using SDK in a DSP56F803, and I want to get a set of data from the
target board. To acomplish this, i use PCmaster. The problem is that in
PCmaster i get the following mesage "waiting for the first trigger".
I read a lot of documentation about pcmaster. Recently, looking the
pcmasterdrv.c provided with SDK, i found the following code in the
pcmasterdrvInit function. #ifdef PCMDRV_INCLUDE_CMD_SCOPE
/* reset scope */
((pcmdrv_sScope *)(PCMasterComm->p_scope))->varCnt=0;
#endif

#ifdef PCMDRV_INCLUDE_CMD_RECORDER
/* reset recorder */
((pcmdrv_sScope *)(PCMasterComm->p_recorder))->varCnt=0;
#endif

I think there are an error due to the copy past technique. Maybe the
second cast must be (pcmdrv_sRecorder *). The PCMasterComm->p_recorder
pointer has the same cast in other places in the same file.

I want if anything could tell me if this is the problem causing the
message i obtain in PCmaster and if yes, how to fix this.

Thanks

Hi Marcos,

Interesting finding you got there. I'm working with CW7.2, Processor
Expert and FreeMaster (formally PCMaster) and the problem is still there. I
tried to have some help form Freescale but no one seem to know what to do.

I'll follow the rest of the thread if there is one.

Good luck Bruno Tremblay
