Config via Protocol - periphery IO default voltage levels

Hi aroamerer,

If they are tri-stated I'd have thought it would work, but will check my circuit.

As regards your question, I'm not sure - I have modified the Linux driver for our own board, but the driver open, probe and close functions are largely the same. I load the driver, program the board, and then when it has finished programming test that I can read some of the FPGA registers my board has, and all is successful. The check that the programmer did on finishing programming was crashing Linux, but then it was asking to read outside of the BAR, so not too surprising. I'm using the driver source that came with an earlier release, for an Altera OpenCL board, so not sure if other drivers work similarly or not.

Cheers,

Simon
