Re: [microblaze-uclinux] Using Chipscope Pro 6.2i
I think that the removal of the opb_mdm instance in mb_vanilla should
solve the excessive usage of BSCANs. You don't need to use the mdm
module when you're using chipscope.
I'm not sure if that'll solve the slice problem. How many slices does
the design occupy without the chipscope core? An ILO monitoring a
one-bit signal shouldn't use too much of the FPGA though.
