The thanks should go to Thomas :) I was interested on solving the debuggin issue (that's possible by routing the JTAG pins to the Mico32, I don't know how exactly but most FPGAs permits to manage the JTAG stream). If not, at least in developing a protocol to upload new firmware. But I didn't have the time to do that. I'm interested on Mico32 running on other platforms so we can keep communicating.
