 * I made some progress, I found that my STM32 is crashing at https://github.com/stm32-rs/stm32h7xx-hal/blob/master/src/pwr.rs#L487-L492

For anyone following newly, original issue: https://matrix.to/#/!BHcierreUuwCMxVqOf:matrix.org/$wepdq7i_9dWtXU9kq0FNTteIS_F0Fyxo_JuIxsPloiM?via=matrix.org&via=catircservices.org&via=tchncs.de

```rust
        // Verify supply configuration, panics if these values read
        // from CR3 do not match those written.
        #[cfg(feature = "smps")]
        self.verify_supply_configuration();

        // Validate the supply configuration. If you are stuck here, it is
        // because the voltages on your board do not match those specified
        // in the D3CR.VOS and CR3.SDLEVEL fields.  By default after reset
        // VOS = Scale 3, so check that the voltage on the VCAP pins =
        // 1.0V.
        while self.rb.csr1.read().actvosrdy().bit_is_clear() {}
