Compile and flash the bootloader and app separately on the AT32F437 development board

1

The app and bootloader are compiled and programmed separately, but it is found that it is not possible to jump from the bootloader to the app program. The offset settings in the app’s platformio.ini are as follows:

board_build.ldscript = ldscripts/AT32F437xM_FLASH.ld
lib_ldf_mode = deep+
build_flags =
            -DAPP_BASE_ADDR=0x08010000
            -DVTOR_TABLE_ADDR=0x08010000
            -DVECT_TAB_OFFSET=0x00010000

AT32F437xM_FLASH.ld

MEMORY
{
FLASH (rx)      : ORIGIN = 0x08010000, LENGTH = 4032K - 64K
RAM (xrw)       : ORIGIN = 0x20000000, LENGTH = 384K
}

We cannot validate anything without the two projects, bootloader and app, being posted in full.
