Hi there,
I'm currently working with a piccolo 28023 on a control card (F2802xx) mounted on a Docking-Stn USB-EMU.
Running a Virtual machine (vmware) with Ubuntu 11.04, in there CCS 5.1.1. Connecting to DSP with Blackhawk USB2000.
While debugging I do several code modifications, then doing the build with Ctrl+B, then CCS asks me if a want to reload the program I'm debugging -> I click yes.
The normal case is that all is ok, and the new program is downloaded.
But now I have destroyed 3 DSPs while working this way! The first 2 times I had a oscilloscope connected and the board was powerd by USB, so I removed the oscilloscope an powered the board with a external power supply.
But unfortunately my last DSP crashed some minutes ago...
CCS says:
C28xx: Flash Programmer: Error erasing Flash memory
C28xx: Trouble removing Breakpoint with the Action "Remain Halted" at... (Emulation package 5.0.471.0)
A popup displays:
Trouble writing Memory Block at... (Error -1156 @0xAE7) Debvice may be operating in low power mode. Do you want to bring it out of this mode?(Emulation package 5.0.471.0)
I click yes -> CCS crashes (closes, process is gone).
From now on I get following error when I try to connect to DSP:
Error connecting to the target:
(Error -233 @ 0x0)
The JTAG IR and DR scan-paths cannot circulate bits, they may be broken.
An attempt to scan the JTAG scan-path has failed.
The target's JTAG scan-path appears to be broken
with a stuck-at-ones or stuck-at-zero fault.
(Emulation package 5.0.471.0)
Now I'm actually downloading CCS 5.5, I will update all the software to the newest (internal update of CCS does not work...).
Questions:
Could older Software, perhaps older drivers really caus DSP damage?
Could it be a virtual machine related problem?
Or what else can cause this damage?
Thanks for your help!
