G491 variants has wrongly defined 128kB RAM instead if 112k

Hello,

the G491 variants have wrongly defined .upload.maximum_data_size parameter in boards.txt -- should be 114688 (112k, according to datasheet; not 128k as G47xs).

Thanks.

Hi @novaksta
Thanks for the issue. It seems you're right.
The RAM entry is extracted from xml file description available within STM32CubeMX database. The RAM size is wrong in G491 files.
Ex:
https://github.com/STMicroelectronics/STM32_open_pin_data/blob/3d64b1076ac7f0bf0f74acf89b9578b530f37ed7/mcu/STM32G491RETxZ.xml#L6C13-L6C14

Could you provide a PR for this, please?

Hi @ndoo and thanks for the PR.
I've updated it because you change all boards_entry.txt but those files are automatically generated and so next time variants will be updated against the STM32CubeMX database changes will be removed.
Instead I've update the boards.txt which is the only take in account by the Arduino build process.
I will raise an issue to fix the database.

Ooh thank you @fpistm sorry I misunderstood the solution 😅

Cheers.

Welcome.
No worry. Thanks for the efforts.
I've submitted an issue to fix the problem in the database. Like this the boards_entry.txt will be automatically fixed when resolved.
