Dstream probe questions

Hello,
I just received a Dstream probe to do trace on an Omap 3530 (CortexA8) processor.
I started to setup the device but I have the following issues:

[1] I installed DS5 & Dstream on a windows XP (SP3) but the USB driver installation of the Dstream fails.
Each time I plug the probe (USB) to the PC, windows ask for the driver to install ... I follow the procedure given by arm and indicate the correct folder for the drivers.
The installation starts with files copy ... but at the end of the setup an error message indicates that the installation failed without giving further indications.
Does someone already had that kind of problem?

[2] As I'm not able to connect the Dstream to the host PC via USB I have connected the probe via Ethernet.
This is working fine but it seems that, when connected via ethernet, it is not possible to do trace capture with the ETM interface.
Looks like it is only possible to use the 4KB trace buffer embedded in the OMAP.
Someone can confirm?

Thanks for your help!

Regards,
Nicolas.

    You are right that the JTAG connection will not handle external trace, but the type of trace is not automatically selected by the cable connected

    The choice between ETB and TPIU (external trace) is made by choosing the platform and DTSL Options.   DS-5 doesn't supply a platform for OMAP3530EVM.   And the closest platforms [Mistral > AM3730, TI > OMAP 3530 (Generic) and TI > OMAP 35XX (Generic)] have only "Debug and ETB Trace" options.  Which platform have you selected in the debug configuration that you are using?

    I suggest you try creating your own platform by using Debug Hardware Config and cdbimporter.  See http://infocenter.ar...h/BGBIICAJ.html,  http://infocenter.ar...m/CIHEJGAB.html and http://infocenter.ar...m/CIHFJGAF.html

    I tried this on my OMAP3530EVM and was able to select the DSTREAM in the DTSL options, but I didn't get any trace clock (or trace).   I suspect there is some target pinmuxing required.
