Arm-none-eabi-gcc ve Makefile kullanılarak derlenen bir STM32Cube projesi almaya çalışıyorum. Ben belirttiniz:STM32F030 başlangıçta Hardfault, __libc_init_array
CFLAGS = -mthumb\
-march=armv6-m\
-mlittle-endian\
-mcpu=cortex-m0\
-ffunction-sections\
-fdata-sections\
-MMD\
-std=c99\
-Wall\
-g\
-D$(PART)\
-c
ve: Ben Sert Fayı takılıyorum MCU önyükleme yaparken FW problems.but olmadan inşa
LDFLAGS = -Wl,--gc-sections\
-Wl,-T$(LDFILE)\
-Wl,-v
. Yığın izlemesi:
#0 HardFault_Handler() at ./Src/main.c:156
#1 <signal handler called>
#2 0x0800221c in ____libc_init_array_from_thumb()
#3 0x080021be in LoopFillZerobss() at Src/startup_stm32f030x8.s:103
#4 0x080021be in LoopFillZerobss() at Src/startup_stm32f030x8.s:103
Backtrace stopped: previous frame identical to this frame (corrupt stack?)
ve başlatma dosyasında bl __libc_init_array
için adım ne zaman Sert Fayı gidebilirler.
/* Zero fill the bss segment. */
FillZerobss:
movs r3, #0
str r3, [r2]
adds r2, r2, #4
LoopFillZerobss:
ldr r3, = _ebss
cmp r2, r3
bcc FillZerobss
/* Call the clock system intitialization function.*/
bl SystemInit
/* Call static constructors */
bl __libc_init_array
/* Call the application's entry point.*/
bl main
Herhangi bir fikir yanlış olabilir?

Atlamak istediğiniz yeri görmek için dosyayı sökün, daha sonra bu adreste bulunan kodu kontrol edin. Belki de bağlantı kurduğun libc ile ilgili bir sorun var, bu da kırık bir sıçrama ya da bir şey üretir. – unwind
@unwind 'b' komutunu kullanarak dallanma olabilir, ancak atlama + 2kB üzerinde mi? – evading
