Hmm, I do not think this one is really true. WinUSB does support vendor commands and this is used in the current libusb-1.0 Windows backend implementation. > The Cypress EzUSB library + EzUSB driver can ... The ezusb.sys driver is now obsolete. The new cyusb.sys driver is quite good though. But it is meant to use with Cypress chips only. So libusb is still better, especially when libusb-1.0 Windows got released with libusb0.sys and libusbk.sys driver support (not yet there). libusbk.sys is the next-gen libusb-win32 driver and library. http://code.google.com/p/usb-travis/ > In contrast, LIBUSB - you *can* send vendor commands :-) > Hence you can write a driver using LIBUSB :-) Yes, of course libusb is better as I am one of the admins of the libusb-win32 project and a tester of libusb-1.0 (both Linux and Windows) . :-) > The above is generally what the linux tool: "fxload" does. > http://linux.die.net/man/8/fxload I use Cycfx2prog under Linux and Windows without an issue. Under Windows, you need to use libusb-win32. It can be built under Windows without modifications. http://www.triplespark.net/elec/periph/USB-FX2/software/ Many examples here work under Linux and Windows (with minor modifications for Windows). http://lea.hamradio.si/~s57uuu/uuusb/uuusb_software.htm BTW, here is one Jtag example with EZ-USB FX2/FX2LP. http://ixo-jtag.sourceforge.net/archive/ixo_de_usb_jtag.html -- Xiaofan _______________________________________________ Openocd-development mailing list [email protected] https://lists.berlios.de/mailman/listinfo/openocd-development
