JTAG Debugger for Cortex-R7

I tried few debugger(hands-on) especially Segger's but those JTAG debugger doesn't suppport Cortex-R7 core.  I also checked few other JTAG debugger(RLINK, flyswatter etc) but cortex-R7 was also not in their list of supported cores on their website. 

Does anybody has worked on Cortex-R7 core  with some debugger or Any clue which JTAG debugger to choose for the same ?
