Sure

Check RCC for correct 48MHz USB FS PHY clock setup.

Cool ! I've tried to use OTG-HS with Waveshare USB3300+NUCLEO-F429ZI but failed. Perhaps i've had a problems with interconnection wires @60MHz ULPI clock.

I think it's close to L052. Unfortunately, there is no proper G0 on the local suppliers stock.

Yes. I will add this option. Usually, ROP1 is used for testing to avoid irreversible chip locking. For production, ROP2 can be used.

@IvanShalnev Actually you can use both PA13 and PA14 as bootstrap pins with the following limitations. PA13 is active low (pulled high) and PA14 is active high (pulled low). Anyway,...

Agreed with this point. It's better to use auto-trimmed HSI48 rather than HSI16 if available. L1 has no similar clock system. L4 can still use MSI for the USB as...

G4 also can use a dedicated HSI48.

@Sfinx I think, there is another cause. See issue https://github.com/dmitrystu/libusb_stm32/issues/103 and fix https://github.com/dmitrystu/libusb_stm32/commit/c3bcfc9456ebd9b5fc6db8010a431fe8a94814cc

* No. This will work for CRC, but not for FNV1A * Not quite. Bootloader verifies flash memory until a checksum collision was found or ```__romend - sizeof(checksum)``` was reached....
