Flashing via SD card

Ugh... Yea, I meant bytes.

Well that is good then. BOOTSZ would have to be set to 00 for that, if I can remember.

Though I might still give that custom bootloader a try to see if I can make it any smaller. (the uMMC one looks like it contains two methods of uploading sketches... If I'm only going go be loading from the sd card then I could probably get rid of half the current code...

Again, I'll keep you posted.

Thanks for the help!
