Hi David, Yes, my emails are relating to building a BORPH enabled Linux kernel for BEE2 but it is due to problem with reading registers. I have run into the same problems as in this thread. It is impossible to read or write registers from user FPGA compiled with 10.1 tool chain, and control FPGA compiled under 7.1. That is why i am trying to build a whole system (user and control FPGA) with 10.1 tools and look if it helps.
