[U-Boot-Users] SystemACE

21 Apr 2007


      Hi,
I have debugged systemace driver and ported it on Microblaze. I use 
SystemACE for loading bitstream to FPGA. But if the SystemACE initializes 
FPGA this part of code sets to zero CFGDONE bit in STATUSREG. And then 
release_cf_lock function resets SystemACE.
I add this part of code to microblaze-git repository. Please test it if you 
can.
Best regards,
Michal Simek
