flash_with_bootloader.ld's rom region ended 512 bytes short of the NVM region it's meant to butt up against (0x1F900 instead of 0x1FB00), leaving a small gap neither region could use. Corrected the LENGTH and the matching maximum_size in boards/versapad.json (128K - 8K bootloader - 1.25K NVM = 121600 bytes, not 120832). Found while double-checking the numbers for a flash-usage breakdown; current 19KB app image is nowhere near either boundary, so this never affected anything on hardware.
