Almost there! Specifically, bootloader upload worked great...
HOWEVER, now when I try to upload (via standard FTDI-FT232 chip),
the Arduino IDE states:avrdude: serial_baud_lookup(): unknown baud rate: 28800How can this 28800 baud rate (different from the standard 19200 or 57600) be made possible in the sketch upload?
In the meantime, I'm trying to look through the Arduino folder for any possible config files that can be edited to allow this baud rate.
That's unfortunate. Seems that AVRDUDE can't use 28800 baudrate. Your bootloader is hardcoded to work at 57600 when running at 16Mhz, so if clocked at 8Mhz only a 28800 baudrate would decode correctly. But if AVRDUDE won't play at 28800 rate your SOL I guess. The bootloader will have to be recompiled to a standard AVRDUDE compatible baudrate I guess, which I can't help you with.
