Hi Claude,

The parameters within a DS-5 .rcf file are used to configure the connection to the target hardware.
The information contained within them consists of both 'box' level connection info (i.e. whether JTAG or Serial Wire Debug protocol, connection clock speed, devices present etc. and so forth) and then individual component level information (e.g. CoreSight base address, CoreSight AP Index and so on).

Without the information within an .rcf file, DS-5 would not be able to connect to a hardware target.

May I ask why the interest in the contents of .rcf files ?

Normally a DS-5 user would :
- open the Platform Configuration Editor (PCE)
- configure an appropriate connection to their platform
- save
- debug

Without having to concern themselves with what is within the files produced by PCE.

Is some information wrong within them, and you want to change it ??

Regards,
Stuart

Hi Stuart,
I was looking at this parameters to try to see if there are some that let us debugging AMP cores. With DStream it is possible whereas with another debugger, there is some missing information that prevent us to debug the cores independantly.
But it sounds it is more on the dtsl side maybe.

Hi,
Ok. For AMP, the connections to the cores are treated separately in DS-5 and the policing of the low-level JTAG/SWD accesses to the DAP/cores is performed by the DSTREAM.

So I guess you would have to see how the other debugger might handle this use-case.

Stuart
