My app starts loading in the programming window at $C000 in page $3F but cannot go beyond $F000. This limits program size to less than 12K bytes, a severe limitation when 512K bytes of Flash are available. The load and erase routines of the Serial Bootloader all reside in $F000 and it can load apps into the same $3F page, so why can't the Serial Bootloader load into other pages of Flash like $20?
