newbie to STM32 needs Assembly Language Start Up Code Help

Hello to all,

I'm a newbie to the STM32 and ARM's in general. I am attempting to utilize the Raisonance RIDE7 IDE with the GNU assembler. I'm at a loss as to how to setup the start up code. I tried but can't seem to make it go! Is anyone willing to share a real basic ''skeleton'' assembly language STM32 startup file (setup for use with the GNU assembler), or might anyone know where I can get more information that could help me write my own. I have a strong background in Assembler, but can't seem to get the right voo-doo in order for the STM32 startup! Thanks and regards, Russ

The STM32 startup for RIDE7 is already available but it was written in C and not in assembler.

Hello, the STM32 demo in this project uses a GNU-assembler startup file, you may use it as an example:

http://chibios.sourceforge.net/

The whole demo is located under ./demos/ARMCM3-STM32F103-GCC The startup-related files are: ./demos/ARMCM3-STM32F103-GCC/ch.ld (linker script) ./ports/ARMCM3/crt0.s (startup file) ./ports/ARMCM3-STM32F103/vectors.s (interrupt vectors table) I hope this can help you. regards, Giovanni

Giovanni,

That was extremely helpful. I can't thank you enough for your help! The example broke things wide open after a couple weeks of nothing! Kind Regards and great thanks! Russ

I am also just starting to use STM32F103 with ARM Ride 7 GNU tools.

Are these files still available? As I think they will save me time. ./demos/ARMCM3-STM32F103-GCC/ch.ld (linker script) ./ports/ARMCM3-STM32F103/vectors.s (interrupt vectors table) I have found this one. ./ports/ARMCM3/crt0.s (startup file) Many thanks Bob

Hello,

the files are still available, this is a direct link to the download page:

http://sourceforge.net/projects/chibios/files

The latest stable version is 1.2.3. BTW, there is also a RIDE7 demo (with project files) in the contributions area, note, it is not an ''officially'' supported download, a user contributed the demo and reported it as working, scroll down in the page in order to see it. regards, Giovanni --- ChibiOS/RT
