Yes since I use the latest FW for the V6 and V7.

For V6/V7 and below, it seems to me Segger has not provided
FW change for more than a year. It is not that unreasonable
to ask V6/V7 J-Link users to update to the latest FW if some
old version does not work with OpenOCD but the recent FW
works with OpenOCD.

V8 is a bit different since it is a moving target and Segger
keeps updating the FW with some versions not working with
OpenOCD and some versions working with OpenOCD.
So we do need to track V8 J-Link.

As stated in the above, FW of V6/V7 has not been updated
for more than a year. FW of V8 keeps been updated.

I check my V7 and the latest FW of the same date as V6.
J-Link ARM V7 compiled Feb 15 2011 11:03:33

V8 FW is still being updated so we do need to keep track of it.
For V6/V7 or earlier versions, I do not think it is worth the
efforts unless Segger updates the FW for then again.
