Does anyone know if it is possible to adapt a C6211DSK to use as a JTAG emulator? It looks as though all that is needed is to attach a cable from the DSK JTAG to the target header and ensure that the DSK's CPU is disabled (or dissconnected). Has anyone tried this? Can anyone think of a reason why it wouldn't work? Dave

I have tried the same idea on motorola DSKs and it works. Your idea should work as long as you have the JTAG connection right. Let me know the result as I am interested too.

Yes, I've done it. No problems at all. I used a Spectrum XDS510PP emulator. The board itself will detect whether an emulator is connected or not as if not it will use the parallel port for getting data Best regards Lars Skade -----Original Message----- From: [SMTP:] Sent: Wednesday, July 12, 2000 6:16 AM To: Subject: [c6x] DSK as EMULATOR Does anyone know if it is possible to adapt a C6211DSK to use as a JTAG emulator?

No it won't work without modifying the 6211 board. I quick check of the circuit shows JTAG inputs to the 6211 are routed through a set of 2to1 muxes, with one side selecting the '8990 and the other the JTAG connector. The selection is made using a pull up on one of the pins that is grounded on the JTAG cable. It may be possible to short the 2 to 1 mux inputs together, so connecting the 8990 directly to the JTAG connector but the PD and TDI pins would still need to be modified out. There is also the issue of timing and drive across the JTAG cable, most of which use a pod to register the output close to the target system.

I was planning to remove the muxes to breakout the connections from the '8990 to go to my target 6211. > It may be possible to short the 2 to 1 mux inputs together, so connecting > the 8990 directly to the JTAG connector but the PD and TDI pins would > still need to be modified out. > > There is also the issue of timing and drive across the JTAG cable, most > of which use a pod to register the output close to the target system. What exactly do you mean by this? If you are talking about the length of cable from the '8990 to the target 6211 I intend to keep this less than 5 inches long. > Hope this helps ( and is correct) > > Andy > ----- Original Message ----- > From: "Tao Zhang" <> > To: <> > Sent: Wed, 12 Jul 2000 13:44:12 +0100 (GMT+01:00) > Subject: Re: [c6x] DSK as EMULATOR > > > I have tried the same idea on motorola DSKs and it works.

Dave, Yes, you can do this. It does involve a few cut/jumpers, but I am aware of a couple of people that have done this with the C6x EVM which was used as the baseline for the DSK. The DSK may be a better platform to do this from the perspective that you can keep the cable from it to your target short. However, the DSK interface is much slower than the PCI interface of the EVM so it would be comparable to an XDS510PP instead of an XDS510 (ISA) card.
