Interesting. Plus it can probably be ported to FreeBSD and avoids installing the Xilinx bloatware that fills your disk with gigabytes of crap when all you wanted was a JTAG tool. > However for programming parallel flash, I have no bscan_bpi > core yet, and as my design contains a P33 nor flash, which prbably isn't > supported for BPI configuration, I won't have a target to test against > soon. It might be interesting to design a "universal FPGA-based flasher tool" that gives an interface to external CFI flash devices through a serial port? (I would prefer not to use the JTAG cores as they aren't portable, even within the same FPGA vendor) With a human-readable set of commands and a shell, like: erase flash, compute CRC, download MCS file to flash, ... ZPU looks like an appropriate softcore CPU for this purpose.
