From: Jaime Andrés Aranguren Cardona on 21 Jun 2005 07:02 Luiz, I don't know too much about the newest ADSP-2136x SHARCs (I'm just starting with this beast!), but, isn't it possible to get some information for reading internal memory, etc, from a host port? Is it mandatory for you to access the DSP via JTAG??? Regards, JaaC
From: oen_no_spam on 21 Jun 2005 09:32 JaaC, Unfortunately the newers SHARCs don't have a host port. I think this was a big mistake, and this is my problem. I was heading a TigerSHARC (TS203), but since it's price changed form $35 to $47, I'm looking for alternatives. If I can't debug the SHARC by myself, I can't use it. And the only way I could find is using the JTAG port. I don't understand why ADI doesn't publish this information. I don't think they do a lot of money selling debug pods. Thanks, Luiz Carlos

From: Ron Huizen on 23 Jun 2005 09:32 We (BittWare) use the ADI emulators for JTAG debug, so have no need to try to figure out and run the JTAG directly. We also have our own "secret" method for doing VDSP debug sessions over the PCI bus to our boards. However, all of our processors (2106x, 2116x, TS101, TS201) have host ports we can use for this. You should contact Analog Devices and see if you can sign whatever licenses and NDAs they may require to get access to this information. It may be much easier, however, to look at something like their USB emulators, and plug this into your board and the PC its in (you did say it had a PCI interface) assuming you're running Windows) and then just use some remote Windows access software (like NetMeeting). We support remote VDSP debug sessions over TCP/IP, but it requires one of our PCI based boards to be in a target system (Windows, Linux, VxWorks) running our remote server to provide access to the DSPs. ---- Ron Huizen BittWare <oen_no_spam(a)yahoo.com.br> wrote in message news:1119527763.620352.259310(a)f14g2000cwb.googlegroups.com... > Bittware, Danville, anyone? > Is this "top secret" information? > > Luiz Carlos >

I have not done a lot of work with the Tiger family yet, and most of what I have done has been mundane tasks in C, not requiring a lot of in-depth knowledge of the chip's architecture. I cannot comment on the Tiger's lack of a host port - out of ignorance. I do know that the host /does/ have access to the TigerSHARCs in our systems. BittWare does have a host-based debugger for the TS101 and TS201. I architected this debugger for the Hammerhead family, but a co-worker implemented it, and then ported it to the TS. Our debugger plugs into VisualDSP++ and looks exactly like an emulator. It's all software based, not requiring an emulator pod. It even supports Tigers plugged into PC's other than the one on which VisualDSP++ is running (remote target). I have used it, and it works well. It /is/ therefore possible to debug TigerSHARC code without connecting to the JTAG. I have also used it in some complex tool chains. For instance, I run VisualDSP++ on a WinXP installed on a virtual machine using VMWare. I do this on my laptop which runs Linux. The laptop obviously precludes the addition of PCI boards. I have used our Remote Target package to connect this virtual XP setup to other PCs running Windows or Linux. So I can open VisualDSP++ on my laptop and have it open a debug session on a TS201 (cluster) installed in a box on the other side of the network. There is no reason it wouldn't work across the Internet too (although I would expect it to be a tad sluggish). Which I think is all pretty cool. To my knowledge, this package is offered only with BittWare hardware. -- Jim Thomas Principal Applications Engineer Bittware, Inc jthomas(a)bittware.com http://www.bittware.com (603) 226-0404 x536 Getting an inch of snow is like winning ten cents in the lottery - Calvin |
