USB downloader and USB second stage bootloader for OMAP44xx =========================================================== aboot.bin --------- aboot.bin is a designed to be a second stage USB bootloader (what TI calls x-loader) for the USB peripheral boot mode of OMAP44xx. Currently it's somewhat pandaboard-centric, but that should be easy enough to clean up -- it shouldn't touch any gpiomux config except (maybe) for the UART. All it does is send a u32 message (0xaabbccdd) back over the USB link, then reads a u32 size from the host. Then it downloads size bytes from the host to 0x82000000 and jumps to that address. usbboot ------- usage: usbboot <2ndstage> [ <image> ] - usbboot will poll every 250ms until it locates an OMAP device (VID 0451, PID d00f) - it then will send the 2ndstage binary to the device - if an image was also provided, it will wait for the 2ndstage to send the go-ahead response (0xaabbccdd) and then send that image
