I worked with the White Mountain Vista ICE Emulator with the 12 ADI DSP 21060 processors. The White Mountain emulator looks inconvenient but pretty stable. I'm trying to work with the same board and with the same White Mountain emulator but under the Visual DSP. The Visual DSP supports White Mountain ICE. My impression that Visual DSP is very unstable when working with the multiply DSP. It hard to load programs more then to one DSP. The simultaneous debugging becomes almost impossible because processors hung. This almost newer happened when I worked with the Vista ICE. Does anybody works with the multiply ADI processors under visual DSP? Is it stable enough? Does PCI or USB emulators works better the ISA ones? Slavik Wexler |

VDSP stability?

Don't know if this applies to you, but are you using one plug-pack to power the various boards and emulator? If so, check for ripple on the 5V supply. wrote: > > I worked with the White Mountain Vista ICE Emulator with the 12 ADI > DSP 21060 processors. > The White Mountain emulator looks inconvenient but pretty stable. > I'm trying to work with the same board and with the same White > Mountain emulator but under the Visual DSP.

How did they make it easier? With VDSP I either select one DXE per processor or select a set from "Recent Programs". > The > simultaneous debugging becomes almost impossible because processors > hung. This almost newer happened when I worked with the Vista ICE. I envy you. I use VDSP with 2 21065L's. When VDSP first came out and this happened it was necessary to shut down the debugger, unplug the ICE from the target, and reset the target. (The 21065L has an integrated wait state generator which I initialize with a known good boot prom. If the CPU attempts to access a region for which ACK never arrives, a core hang is guaranteed. VDSP can't seem to recover from this on its own.) > Does anybody works with the multiply ADI processors under visual DSP? > Is it stable enough? Does PCI or USB emulators works better the ISA > ones? What is enough? I can work, and the program is much better (more stable, more recoverable, faster) than it's initial release, but a lot of improvement is possible. I use the Summit-ICE (PCI) version and it's usable. We've made initial attempts with the Aspex-ICE (USB) under Win95 (since VDSP can't be installed yet on Win2K) but recovering from hangs is even more painful with the USB pod: One must power down the pod (ie. unplug it), power it up for 30 seconds *before* plugging it into the PC's USB port, and then start VDSP. The pod does not give an indication of when it's done booting and it's ok to plug it in to the PC. Kenneth Porter Kensington Laboratories, Inc. mailto: http://www.kensingtonlabs.com |
