That is arguable. Yes libwdi/Zadig makes it easier to replace FTD2xx driver with WinUSB so as to use libusb-1.0/libftdi-1.0. On the other hand, libusb-win32's GUI Inf-Wizard is also easy to use so that user can replace ftd2xx driver with libusb0.sys so as to use libusb-win32/libftdi-0.1x under Windows. Moreover, libusb-win32's GUI Filter Wizard makes it very easy to add filter driver on top of the existing ftd2xx driver in order to use libftdi-0.1x. The user does not even need to repace the ftd2xx driver so they can continue to use other tools relying on the ftd2xx driver. The libusb-win32 filter driver is also perfect for use with other Jtag device like J-Link. You can keep using Segger's driver so that you can continue using IAR/Keil/etc. And you can add the filter driver in order to use OpenOCD. -- Xiaofan _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
