Question

Hey everyone, wish a good time for you. I wrote a

simple LED-Blink program with CMSIS for a stm32f030
> compiled it with:
arm-none-eabi-gcc -DSTM32F030x6 -mthumb -mcpu=cortex-m0 --specs=nano.specs --specs=nosys.specs -Wall -fmessage-length=0 -ffunction-sections -fdata-sections -I./cmsis
/CMSIS-5.8.0/Core/Include -I./device/STM32F030x6/include -Os -c main.c -o main.o
> linking it with startup_stm32f030xx.S (startup.o) and linker-script:
arm-none-eabi-gcc -T/home/e72f46e/projects/CMake-Sample/device/STM32F030x6/STM32F030x6_FLASH.ld --specs=nosys.specs --specs=nano.specs main.o startup.o -o test.elf
> extracting hex code from elf file:
arm-none-eabi-objcopy -O ihex
test.elf test.hex
> flashing it using st-flash at address 0x8000000:
st-flash write test.hex 0x80000000
- wired connections from header-board (PA4) to the LED is OK.
It doesn't work ... any advice ?
Thanks.

First, try resetting the device. it sometimes happen that ST-Link won't release the reset line.

Use that: https://pastebin.com/ to demonstrate your code to everyone. I bet you'll be amazed with the number of help-wishers here if you do just that.
