Hi, Thanks for the reply. About the chance of having two JTAG devices internally, I don't think it's likey to happen. If it were the case, why did it work right with an Mountain-ICE which is also a JTAG emulator? Nowhere in the documentation about 2116x is anything mentioned about dual JTAG. It only has dual processor core, but just one JTAG interface. Is not a multiprocessor chip, but a SIMD DSP. Indeed, I tried setting two DSPs chained in the configurator utility, but now the message when setting the debigging session was like "Only 1 DSP found, you're listing 2. Check the configuration utility". What a confussion!!! I am using the very latest drivers from ADI website, ICE 6.01 bundle. I am aware of the jumpers in the POD for I/O voltage configuration. As the 2116x are 3V parts, it's configured in such a way that the led is on -> working for 3V chips. What I talked about are some (3) jumpers on the Summit-ICE PCI card itself, not in the pod. Do you kow what are those for? Should I leave them unconnected? I checked, and the address I write on the configurator matches the one on the control panel. Otherwise (and I also tried) it wouldn't run the ICETest utility. Thanks for the final clarification. I know it is better to post to the newsgroups, so the public DSP knowledgebase grows for everybody interested. I just sent the e-mail directly to you because (and I've experienced that) some times posting to the newsgroup takes longtime while approved by the moderator. And I was looking for a quick answer. Please, excuse me. I'll try with a '65L EzKitLite, just for comparision purposes, so we get into a common arena for discussing.

Could they possibly implement two JTAG devices internally?

Double-check the ICE-Configurator setup, maybe. > I noticed there are some jumpers shipped with the Summit-ICE, as well > as some pins, I suppose for using the jumpers, but there in no > information on the documentation about them. Might this be the cause > of the problem? How to solve it? The Summit has a 3V/5V jumper to handle different SHARC's. The newer ones (21065L on) should be set to 3V to match the CPU supply. When we were first starting out, we had a PCI devel board that used a 21062 (5V part), plus the 65L EzKit, so we drilled a hole in the pod case to make it easy to move the jumper to match the target we were using. > Also I should say my base address for Summit is DA00.

Although I personally think the Configurator shouldn't need to worry about that and should just use a logical index from the driver to select which device to use. This is a protected-mode OS, and userland applications shouldn't need to worry about I/O addresses. Sometimes this stuff feels like a crude port from a DOS or Win3.1 product. BTW, please don't send questions directly to me. If I see it on the list or the newsgroup and I have an answer and time I'll answer it. I'm far *less* likely to respond to stuff sent direct to me, as it doesn't help the user community, and that's my primary objective in participating. _____________________________________ Note: If you do a simple "reply" with your email client, only the author of this message will receive your answer.
