SQNx010 RealView Multi-ICE Support

Are the Sequans SQN1010 or SQN2010 processors supported by the RealView Multi-ICE?  The SQNx010 has an ARM926EJ-S core but there are two other devices on the JTAG bus.  I have heard that someone got a RealView Multi-ICE working on these processors but they required addition software from ARM.  The SQNx010 is not listed on the supported processors so I am dubious.  But if one company got the ICE working, I was hoping the support might be available directly from ARM. 

Thanks.

    I haven't used the processors you mention, however, I do know that what you're describing is quite normal. You can probably ignore the other devices on the JTAG scan chain. They are used for various things (and this is specific to the board), but for straightforward debugging they will not usually be required.

    A good example of where this is used is in a multi-core processor (or a multi-processor SoC) with a single JTAG port. In this case, you will see multiple cores in the JTAG scan chain.
