svdtools.patch.MissingPeripheralError: Could not find WWDG
How do I solve this?

Ah, looks like it's CFR not CFG, a typo in my suggestion earlier. https://stm32-rs.github.io/stm32-rs/STM32H7x5_CM7.html#WWDG1:CFR

edit: Also, it can be WWDG or WWDG1 or WWDG2, so better use the same selector as the g4 patch to catch them all.

Ah, I should have caught that. The G4 doesn't have a patch for this, so I guess the SVD was already correct in that regard.

Strange... The original svd file says this:

...
    <peripheral>
      <name>WWDG</name>
      <description>WWDG</description>
      <groupName>WWDG</groupName>
      <baseAddress>0x50003000</baseAddress>
      <addressBlock>
        <offset>0x0</offset>
        <size>0x400</size>
        <usage>registers</usage>
      </addressBlock>
...

Is it renamed somewhere?

Edit: Ah, I see, some of the H7's have WWDG and some have WWDG1

I think you should be able to just have a single h7_wwdg.yaml and write it like:

"WWDG,WWDG?":
    ...

(which is what the G4 WWDG file does:

I think you should be able to just have a single h7_wwdg.yaml and write it like:

(which is what the G4 WWDG file does:

stm32-rs/peripherals/wwdg/wwdg_v2.yaml

Line 7 in 0121355

"WWDG,WWDG?":

)

But will that change the bitWidth property as well? That seems important to change...

I mean, in the devices/common_patches/h7_wwdg.yaml, which changes the bitWidth, you can match against all spellings of WWDG, rather than having h7_wwdg.yaml and a separate h7_wwdg1.yaml, and that way also match on WWDG2 (which some H7s have).

Awesome! Thanks for your patience and help :)
