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 !
