Hi Jude,
What example did you use as a basis for your counter configuration? It looks like you may have overlooked the advice in the thread that Tom pointed out.
In addition, I'm wondering if your method "Cpci6230::myGPCT()" is the entirety of the code you use to configure and read from the counter. If it is, then you're missing a call to tTIO::setAddressOffset() and any subsequent register I/O will be directed at the wrong addresses. This could be the reason why AO updates cease after calling Cpci6230::myGPCT() -- by configuring the counter using the wrong register addresses, the board has entered an unknown or unstable state.
