Note that adding or removing the flag does change the binary size quite significantly, around 7.5kB of flash of difference between with and without. The RTOS has created the main thread that is being started and we don't go any further than the toolchain init (creation of malloc mutex, env mutex and _libc_init_array (global variable allocation). Meaning that the error seems to occur quite early in the process. mbed-os/rtos/TARGET_CORTEX/rtx5/RTX/Source/rtx_thread.c:1128 mbed-os/rtos/TARGET_CORTEX/mbed_boot.c:99 mbed-os/rtos/TARGET_CORTEX/TOOLCHAIN_GCC_ARM/mbed_boot_gcc_arm.c:83 Note: automatically using hardware breakpoints for read-only addresses.īreakpoint 1, 0x0800850c in _stack_chk_fail () mbed-os/targets/TARGET_STM/TARGET_STM32F1/TARGET_NUCLEO_F103RB/device/TOOLCHAIN_GCC_ARM/startup_stm32f103xb.S:76
On another target (custom board), I've been doing some gdb and I get the following :ĭump of assembler code for function _stack_chk_init:Ġx080084e4 : ldr r3, (0x80084f4 )Ġx080084ea : sub.w r2, r2, #16121856 0xf60000 I've modified the blinky example to add a printf as first line of the main, it doesn't print. What I'm getting is *** stack smashing detected ***: terminated. Copy the binary to your target then open the serial communication.
Then compile using GCC_ARM and the edited profile like this mbed compile -t GCC_ARM -profile mbed-os/tools/profiles/release.json.
