The point of the tristate buffer is to allow a reset circuit to be connected to the Reset pin at the same time. Do you have one? If you simply connected the output from the buffer to the reset pin then you will have a problem. Yes, but Gopal Amlekar in the original post said:
DTR pin is connected to RST pin of controller through a tristate buffer in exactly the same way as shown in Flash magic manual. My questions were aimed at, whether Gopal did not upgrade to the newest V7 of the bootloader and then in some way switched it to the "always bootloader" mode... JW |
