Generic_F030RCT missing?

[Mangy_Dog]

So got a project using this chip. While the Arduino core stm32 lists this chip in its variants, its missing from the boards list when creating a new project or setting a project, at least in sloeber.
I installed the core as per the guide here https://github.com/stm32duino/Arduino_C ... w-to-debug

Do I need to create a custom board entry in the core and point it to this variant? If so... how?

You can find here how to declate the generic:

A PR?

Also thanks will go through the guide now.

A Pull Request on GitHub.

Ahh might do... but later.
The current custom isnt the best config at the moment... getting around a bad crystal selection. So its slightly underclocked.
After the fix ill try to remember to pull then push the config up.

2 Problems.
It doesn't appear that optimisations are being applied. I have a near empty program with just the sleep library attached. And 3 lines of code. And im getting a 112kb binary... -Os is selected.

Also going by power readings of my board. It appears the clock settings grabbed from CubeIDE are not being applied. And its running at 8Mhz.
Now as I mentioned there has been a mistake on this prototype, where a 25mhz clock is attached. But through the configurator I got this to 45Mhz.
So I should expect to see similar power readings from the datasheet.
Though Im only seeing around 7mA at wake state. Which suggests the STM32 is underclocked to 8mhz...
If a bad clock config is applied does it default to 8 or does it just not run?

Binary size difference appears to be Newlib Standard vs Newlib nano setting... Not entirely sure what newlib is...
Clock situation still appears to be happening.

Hard to help without the code you add.

Its really just a really basic board testing program.

To be honest even 33kb seems like a large binary for that program...

You can optimize several things as explained in the wiki.
About code, I talk about the variant and the update you made else can't help on the clock issue. Some hardware info can help also. Like HSE? LSE?....
