Can't find my Nucleo F091

[robothito]

Hello
I am reading the preview version of your book.
When trying the “Hello World” example (Pag 49) I do as the book says but when selecting STM32F0xx in the next screen I can’t find my STM32F091 selection.

I suspect something is wrong with GNU Arm Plug in..

Can I get some help here please?

As I said I use STM32F091 Nucleo

Thanks

Hi,
You are right: the template for the STM32F091 MCU is missed. In this phase, you can safely use the template for the STM32F030: the example will work the same.

However, take in account that the vector tables for the two MCUs differ, so if you are going to do something more advanced with your board, then you need to pick the right vector table for your Nucleo. However, the hello nucleo example will work.

Regards,
Carmine

Thank you very much for your reply.

How do I pick the right vector table? (I am planning to use SPI, and interruptions later- I dont know if that qualifies as advanced)

You can download this file:

https://github.com/cnoviello/mastering-stm32/blob/master/nucleo-f091RC/system/src/cmsis/startup_stm32f091xc.S

Place it in the same folder where you fine the startup_stm32f030xb.S and delete the startup_stm32f030xb.S. Don’t forget to rename the filename from startup_stm32f030xb.s to startup_stm32f030xb.S
