There might be incompatibilities between the libftdi version and the libusb-win32 version. I need to carry out some investigation myself to see if the 1.1.14.3 version is compatible with the libftdi.dll from Freddie (libftdi-0.17). If not, probably I will post a new libftdi.dll myself (probably libftdi-0.18). In the mean time, please try to use the libusb-win32 device driver version packaged in Freddie's version (0.1.12.2). You should not need to copy the dll to the C:\Windows\system32 by yourself. Something is wrong in your driver installation procedures. Please follow Freddie's instruction. If you are using 32bit XP, you should find libusb0.sys under C:\Windows\System32\drivers and libusb0.dll under C:\Windows\System32. And the version should be 0.1.12.2 for both files. -- Xiaofan http://sourceforge.net/projects/libusb-win32/ _______________________________________________ Openocd-development mailing list [email protected] https://lists.berlios.de/mailman/listinfo/openocd-development
