hi,

I try to compile a minimum program using stm driver libs. but I can't compile without error about '__aeabi_uidiv' from line 1083 of stm32f0xx_rcc.c : pllclk = (HSE_VALUE / prediv1factor) * pllmull;

I think the problem come from the linker and I have added path of the libgcc.a in ld flags in my makefile

LIBGCCARM = ${GCCARMPATH}/lib/gcc/arm-none-eabi/${GCCARMVERSION}/${GCCARMARCH}

LFLAGS = -L${LIBGCCARM} \

-lgcc \

-nostartfiles -T$(LKR_SCRIPT)

the linker find correctly the lib, but the error occurs always...

thanks for your help

    AFAIK, the library should be the right one.

    Perhaps you can check it with objdump or similar, to see if the symbol (function) is really there.

    Hi,

    I've found in libgcc several lines about __aeabi_uidiv:

    line 68

         00000000 g     F .text    00000000 .hidden __aeabi_uidiv

    lines 2918, 2933, 2989...

         00000000         *UND*    00000000 __aeabi_uidiv

    an idea?

    thanks

    Looks like it's there.

    Can you post the actual error message from the linker ?

    Does it work if you drop the '

    -fno-builtin -ffreestanding -nostdlib

    ' flags ?

    Ignore for a second that this is a different processor, I don't have time to stand-up a CM0 example, look at the other options

    This is how I compile for the H7

    Compiling file: main.c

    arm-none-eabi-gcc -c -mcpu=cortex-m7 -mthumb -mfpu=fpv5-d16 -mfloat-abi=hard -Os -ffunction-sections -fdata-sections -Wall -Wstrict-prototypes -Wextra -std=gnu89 -g -ggdb3 -fverbose-asm -Wa,-ahlms=out/main.lst  -DUSE_HAL_DRIVER  -DSTM32H743xx  -DUSE_STM32H743I_EVAL  -MD -MP -MF out/main.d -I.  -Iinc main.c -o out/main.o

    This is how I link for the H7

    Hi I (re)install arm-none-eabi toolchain -> same result

    I try the same type of compil for stm32F103 (minimal boot projet, same toolchain), it's ok, no error. so the toolchain is correct for f103...

    I install eclipse +arm mcu pluggin, using the same toolchain. I try a minimal projet, blinky led, it's ok.
