samples: subsys: usb: dfu-next: unable to get DFU working

[henrikbrixandersen]

Describe the bug

I am trying to get USB DFU working with the samples/subsys/usb/dfu-next/ on the frdm_k64f board based on the instructions from https://docs.zephyrproject.org/latest/samples/subsys/usb/dfu-next/README.html#building-with-flash-backend-enabled, but the sample results in UDC error events printed to the Zephyr console while uploading, and the uploaded image is invalid.

Regression

• This is a regression.

Steps to reproduce

1. west build -b frdm_k64f/mk64f12 --sysbuild samples/subsys/usb/dfu-next/ -- -DCONFIG_APP_USB_DFU_USE_FLASH_BACKEND=y -DSB_CONFIG_BOOTLOADER_MCUBOOT=y -DCONFIG_MPU_ALLOW_FLASH_WRITE=y -DSB_CONFIG_BOOT_SIGNATURE_TYPE_NONE=y
2. west flash -r pyocd
3. sudo dfu-util -l

dfu-util 0.11

I have just tested the same sample, same configuration on the lpcxpresso55s16 board. There it also logs a couple of UDC error events, but otherwise works:

[00:00:26.450,000] <err> usbd_core: UDC error event
[00:00:26.450,000] <err> usbd_core: UDC error event
