Plotting via BTC on BF561

I'm having trouble getting signal plotting through the background telemetry channel to work properly on the BF561.

I'm currently using the BF533 fftDemo for BTC for testing (one of the examples provided with VDSP++). This program runs fine without changes on the BF561.

When running on the BF533, both the BTC Memory window and the plot windows work as expected. On the BF561, the BTC Memory window still works as expected, with periodic updates and correct values. Strangely though, the plot window does not work at all when using auto refresh and BTC. Whenever I change the auto refresh settings, the window updates once, but gives a completely unexpected plot. Thereafter, there are no updates. If auto refresh is set to run/halt method, everything works fine. I am using VDSP++ 5.0 update 9, with an HPUSB-ICE emulator.

 

Any help on this issue would be appreciated, and I am also quite interested to know if others are able to reproduce the problem.
