Hi,
in SDK v9, i tried to compile the bootloader example, but:
/usr/lib/gcc/arm-none-eabi/5.3.0/../../../../arm-none-eabi/bin/ld: region `FLASH' overflowed by 6944 bytes
why does the bootloader need so much stuff in the first place? like scheduler, timer, pstore, etc?
according to the map file, the .text section is 22296 bytes here is it parsed with a quickly hacked together script:
