Where is STMicroelectronics.stm32c5xx.2.1.0.iar.zip

Trying to build a NUCLEO-C562RE project under IAR 9.60.4. Included with the output is an folder, IDEs_patches/EWARM and a readme,md outlining how to add support for the new MPU. But the patch file referenced in it is no where to be found. Searched my local drives, ST’s site, ST’s Community, ST’s github but  can’t find “STMicroelectronics.stm32c5xx.2.1.0.iar.zip”

I’m glad ST has decide to distribute a patch so I don’t have to upgrade to the latest IAR every time a new CPU comes out (my company tries to use a consistent version across projects) but without the patch file, IAR does not recognize the C564 as a target.

Hi ​@markr61,

Thanks for your question, and welcome to the ST Community.

The patch is available in the DFP pack, under the location where the packs are installed:

C:\Users\<UserName>\AppData\Local\stm32cube\packs\STMicroelectronics\stm32c5xx_dfp\2.1.0\IDEs_patches\EWARM

As you mentioned, the generated project currently includes the IDEs_patches/EWARM folder, but it contains only the README file and not the actual patches. This is a known limitation, and we are currently discussing improvements to address it.

An internal ticket is already tracking this case: CDM0060827 (This is an internal tracking number and is not accessible or usable by customers).

I’ll keep you posted with any updates.

Best regards,

Sara.
