Sam, thanks for the reply. It would have been great to avoid using windows in the process, but it was too good to be true. I'll device a workaround. Maybe something as simple as logging into windows to flash the board. I'm running a buildroot linux distro and a hypervisor on top of a synthesized leon3 microprocessor and last night I was able to connect to the leon3 through Gaisler Research's GRMON utility from linux. I haven't tried it yet, but it seems that GRMON has the ability of transfering a binary image to the spi flash, so I am going to look into that.
