BF527 NFC and MDMA hang

I am using the MDMA channels on a BF527 heavily, and I am also using the NFC controller DMA. They each work on their own, but if I try to use them both at the same time, the BF527 hangs so badly the HPUSB-ICE debugger wants to disconnect. Adding critical sections around the NFC code seems to help, but with the debugger losing control of the processor it is very difficult to find the root of the problem. Any suggestions?


I have noticed that anomaly 05000500 for the BF548 describes a similar problem, but it is not listed as a known anomaly for the BF527. Could it happen on the BF527?
