Stack misalignment

Did you setup the reset vector? On reset he word at 0000 goes to sp. The word at 0004 goes to pc. One might expect sp=FFFFFFFF if the reset vector is erased and not programmed.

I use IAR toolchain and STM32F101C6T6 as target.

When I download my code to start debug the J-Link driver return the following error:

Stack pointer is setup to incorrect alignment. Stack addr=0xFFFFFFFF.

My application's main is empty. I just include the peripherals driver and IAR's startup file.

Can anyone help me?

Thanks.

Mauro.

Agree w/picguy.

However - more basic - have you tried your J-Link with an ''official'' eval/dev board? Always useful to have something ''known good'' to avoid the dreaded, ''maximum randomness.'' (i.e. new hw, new sw, new tool, new IDE etc)

ST-One32 advises that we check Segger site - download the newest sw for JLink.

I would beg/borrow/steal basic IAR or ST eval board - and get that to work before the debug of (I assume) your custom C6T6 pcb. Good luck...

Hi Mauro,

You can try to run first the latest templates from our web site

http://www.st.com/stonline/products/support/micro/files/stm32f10x_stdperiph_lib.zip

then go to this subdirectory :

\stm32f10x_stdperiph_lib\Project\Template\EWARMv5

Do not forget to change ''your target'' as shown below since you use Low-density devices which is compatible with STM3210B-EVAL board, else you will get a similar error :-).

Hope this helps you.

Cheers,

STOne-32.
