SBSFU: The binary image to be installed overlap with the trailer area Hello,We have a software project with STM32H7B3 MCU using SBSFU for bootloader and installing updates. We are using one download slot and one active slot and have been very tight on flash size and have often had to reduce binary size. Normally, this is not a problem since we get a compilation error from the linker script when binary size becomes too big. In the linker script we have:ISR_VECTOR_START = __ICFEDIT_SLOT_Active_1_start__ + 0x400; /* Cortex-M7: align the init vectors on 0x400 */
APP_ROM_START = ISR_VECTOR_START + VECTOR_SIZE;
APP_ROM_END = __ICFEDIT_SLOT_Active_1_end__;
APP_ROM_LENGTH = APP_ROM_END - APP_ROM_START + 1;
/* Specify the memory areas */
MEMORY
{
DTCMRAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K
RAM (xrw) : ORIGIN = 0x24000000, LENGTH = 1024K
ITCMRAM (xrw) : ORIGIN = 0x00000000, LENGTH = 64K
ISR_VECTOR (Rw) : ORIGIN = ISR_VECTOR_START, LENGTH = VECTOR_SIZE
APP_ROM (rx) : ORIGIN = APP_ROM_START, LENGTH = APP_ROM_LENGTH
}This makes APP_ROM_END equal to 0x08
