I searched the web for USB based JTAG cables with open source drivers, but there aren't many of those available, it seems. The best match seems to be the JTAGkey/JTAGkey-Tiny from Amontec [1] - a solution based on the FTDI FT2232L USB UART IC (but I think these cables are somewhat expensive compared to their complexity). However, this leads on to the next problem. My old parallel port cable is supported by the devel/jtag port from the openwince [2] project. However, this software is quite a mess. It hasn't seen a release since late 2003, new features are available as a mix of 3rd party and upstream CVS patches, and it doesn't support any USB based JTAG cables. The JTAG software found in the OpenOCD [3] project, however, seems to support USB based JTAG cables such as the JTAGkey - but it isn't in ports yet, so I guess this is not what other FreeBSD developers/users use? My question - before I choose to either bite the apple and buy a JTAGkey or construct my own USB JTAG cable - is: what do you guys'n'gals use for your everyday JTAG needs? Which cable? Which software? I can't be the only one in need of an modern, open source friendly JTAG solution :) Regards, Brix [1] http://www.amontec.com/ [2] http://openwince.sourceforge.net/jtag/ [3] http://openocd.berlios.de/web/ --=20 Henrik Brix Andersen --GRPZ8SYKNexpdSJ7 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) Comment: GnuPG signed iD8DBQFGbcF5v+Q4flTiePgRAuYEAJ9tK3hbfFuC7rPmZQTHvzEqmpf9pgCgreYO pZ27k22Ticnzsyn3EzdTZHs= =BiFM -----END PGP SIGNATURE----- --GRPZ8SYKNexpdSJ7--
