ARM DS-5
DSTREAM
Official debugger
ULINKpro
Might also work
Segger
Mixed information about j-link support. I believer it was added briefly and then taken out. You also need a special license from Segger. So, although its possible, its a lot of overhead. You should really use DSTREAM if you can
"RDI support was deprecated a while ago and dropped for RVDS 3.0, so DS-5 Development Studio does not support it. The supported debug probes for DS-5 are currently DSTREAM, ULINKpro & ULINKpro D. Although J-Link isn't currently supported, the RDDI interface used by DS-5 is public and can be used to add 3rd party support for debug probes. You would have to ask Segger about this though."
