I know i've seen it but to program the usb or uart bootloader one needs to have access to a device programmer , the bootloader can only be programmed by a hardware parallel device programmer(i dont have one) not through USB or UART. If i have the programming algorithm and connections for address,data lines i can easily program it. thats what im looking for ,Thankyou

A device programmer can be had for quite little money !
