For whatever reason, I don't have the same memory initialization issues when I use a Nucleo-H533RE. I can't use my Nucleo-G431RB for testing, as it doesn't expose the USB port.
All said though, I never see the Zephyr USB-Device-Next stack initialize on the Nucleo-H533RE. When I use a Nordic nRF52840-DK, I can see the USB stack come online with:
usbd: msg_cb: USBD message: VBUS ready
However I don't get the same from my H533RE. From what I can tell, USBD never "really" starts up, though I don't see warnings or errors to say why.

Hello @JayBeavers,
Could you share the memory regions defined in your DTS file and linker script?

&flash0 { partitions { compatible = "fixed-partitions"; #address-cells = <1>; #size-cells = <1>; slot0_partition: partition@0 { label = "image-0"; reg = <0x00000000 DT_SIZE_K(252)>; }; /* Set 4Kb of storage at the end of the 256Kb of flash */ storage_partition: partition@3f000 { label = "storage"; reg = <0x0003f000 DT_SIZE_K(4)>; }; }; };
I'm using the default linker scripts as generated by west's cmake export.
