XDS510 bought from ebay

Started by gsmt...@gmail.com April 22, 2010
Hi, I bought a XDS510 USB2.0 j-tag emulator from WWW.CSMINGWEI.COM. I wired it with a TMS470 (ARM7TDMI, inside in a radio, only this I have at my hand). The CCS V3.3 installed with it working but crashes a lot of time if stepping the unit in disassembly. Memory read/save does not working.
If I use xdsprobe.exe to test the hardware everything is OK, but I ALWAYS got an error :

Starting the Counter1 and Counter2 Test.
Event3 pin read back of one failed.
Counter1 carry bit test failed at bit ff.
Event3 pin read back of one failed.
Counter1 carry bit test failed at bit ff.
Event3 pin read back of one failed.
Counter1 carry bit test failed at bit ff.
Event3 pin read back of one failed.
Finished the Counter1 and Counter2 Test.

Is this normal or I have something wrong with my XDS510? Maybe this counters are related and not present in my target?
Please advise, I want to know that my emulator is working well or not.
Thanks very much!
