I do not use FTDI based Jtag tools. But I think libftdi is based on libusb. So it will not work under Vista 64 bit (and the upcoming Windows 7 64bit) since libusb-win32 does not work under Vista 64. FTDI's D2XX driver and DLL support Vista 64. The current use of libusb 0.1 and libftdi may limit the speed of USB communication. Moving to libusb 1.0 may improve the situation. http://www.nonpolynomial.com/archives/2008/04/libusb-libftdi-latency-and-my-own-stupid.php -- Xiaofan http://mcuee.blogspot.com _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
