/* * This program connects to an FTDI chip via libusb and commands that FTDI * chip to erase its EEPROM in one fell swoop. This operation is known * to work on FT2232C/D chips with 5V-powered EEPROMs, but is NOT appropriate * for FT232R. This operation is also not recommended for external EEPROMs * powered with 3.3V, as typically used with FT2232H. * * The present version has been converted to use our local libraries * (libftmini and libuwrap) instead of libftdi - thus the external dependency * is only libusb. */ #include <sys/types.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <usb.h> #include "../libuwrap/find_dev.h" #include "../libuwrap/open_close.h" #include "../libftmini/eeprom_func.h" main(argc, argv) char **argv; { struct usb_device *dev; usb_dev_handle *usbh; if (argc != 2) { fprintf(stderr, "usage: %s device-selector\n"); exit(1); } dev = find_usbdev_by_desc_string(argv[1]); if (!dev) { fprintf(stderr, "error: specified USB device not found\n"); exit(1); } usbh = usbwrap_open_dev(dev, 1); ftmini_erase_eeprom(usbh); usbwrap_close_dev(usbh); exit(0); }
