serge Posted July 31, 2015 Share Posted July 31, 2015 Hi All, I am using the HS2 to drive ARC based system through the metaware debugger. Some target require low speed communication so I use metaware speed reduction switch -prop=dig_speed which must be translated to some Digilent speed settings call. The issue is that although the speed gets globally reduced, looking on the scope, one can see short TCK pulses of 200ns, irrespective of the speed settings, inserted in an otherwise reduced clock signal. Even at speed as low as 200KHz this issue remains. This causes target attach failure. Picture describing the issue is attached. I downloaded the latest runtime on digilent support site but still getting old drivers signature: ===== Digilent Adept =====Adept System Rev 2.7Adept Runtime Rev 2.16Adept Application Rev 2.4.2Copyright © 2010 Is this expected, any new drivers available ? Are there some workaround to fix the issue ? We acquired a large number of HS2 so fixing this issue is crucial for us. Best regards, Serge Link to comment Share on other sites More sharing options...

Question

Hi All,
I am using the HS2 to drive ARC based system through the metaware debugger.
Some target require low speed communication so I use metaware speed reduction switch
-prop=dig_speed which must be translated to some Digilent speed settings call.
The issue is that although the speed gets globally reduced, looking on the scope, one can
see short TCK pulses of 200ns, irrespective of the speed settings, inserted in an otherwise
reduced clock signal. Even at speed as low as 200KHz this issue remains. This causes
target attach failure.
Picture describing the issue is attached.
I downloaded the latest runtime on digilent support site but still getting old drivers signature:
===== Digilent Adept =====
Adept System Rev 2.7
Adept Runtime Rev 2.16
Adept Application Rev 2.4.2

Is this expected, any new drivers available ? Are there some workaround to fix the issue ?
We acquired a large number of HS2 so fixing this issue is crucial for us.
Best regards,
Serge
