Hi,

You  have to enable the GPIO-F first with  this code :

RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOF, ENABLE);

Hope this helps you.

Cheers,

STOne-32.

I think I found the problem...

the linker and startup script for gcc from the lib 3.1.2 is useless. compilable, but does nothing. I keep everything the same, but use another linker and startup not from STM32, then everything works just fine. all the interrupt, LED ... etc are working as expected

Thank you  for your reply STOne-32

I'm sorry that I didn't post complete main by mistake because I put all of the config content in a separate file and just call them from main.c. below is the full main.c which turns on LED. my main.c currently calls config for Clock, GPIO and interrupt. interrupt for DMA1CH1 getting value from ADC1 is enable now but I'm only clearing the IT flags in interrupt functions void ADC1_2_IRQHandler(void). I don't think that interrupt are a problem here, so I just exclude them to prevent distraction, but  I'll post them all if you think it's necessary.

Same here! Would be nice to have a working GCC linkerscript.

I have the same problem. Which linker and startup are you using?
