Better solutions use software like "avrdude" or (not quite yet, except with JTAG) "openocd". (Where "better" includes more testing and a supportive user community. There's also a lot to be said for the "AVR Dragon" if you don't want to hack that part of your toolchain before you can get Real Work (tm) done. Last time I needed a quick'n'dirty AVR-ISP programmer I bitbanged it with an FTDI usb-to-serial adapter; but the "avrdude" team hasn't, as far as I know, merged such support yet. I'd discourage kernel support for such stuff, "avrdude" does well with parport bitbanging from userspace. AVR's ISP protocol is simple; at a hardware level it's SPI plus a RESET signal. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
