I wonder are there any other people on this list using jtag adapters who would be willing to share a list of devices. I am looking to purchase one and it would be great to have a list of known devices so that not only me but others can have a list of devices known to work on FreeBSD. Anyone out there w/ jtag adapters care to chime in about their devices?

FWIW, (and unless you are looking for the full "iMPACT" experience) I have successfully programmed both Altera (now Intel) and Xilinx fpga's using OpenOCD and 'jtag' (from UrJTAG) - both tools run native on FreeBSD. xcs3prog alson run native on FreeBSD, but I haven't found a "cable" (aka JTAG adapter) that works with it yet.

My use case is more specific (and thus perhaps less of a lofty goal?). I want to access a usb-based fpga jtag programmer from a linux vm (specifically using a xilinx tool like "impact"). ___ freebsd-usb@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"

My use case for having direct access to usb devices in a bhyve vm could allow rapid development of USB drivers for FreeBSD by sniffing the packets being sent over USB to the bhyve guest and reverse engineer drivers so that we can write native drivers for common devices that aren't supported on FreeBSD yet. I had to put that on the back burner for a bit since there's a lot more pressing FreeBSD issues that I am working on. What's your use case?
