Thank you for your open-source sharing. When I use the examples, I always prompt NRF52-CMD-CHECKSUM-ERROR like this：

My Device is nRF52480 MDK USB Dongle，Use this method uf2boot to convert hex to UF2。Then updated firmware。

I also meet the same question. It seems that the c in raw_receive() is not correctly resolved.

I was able to successfully program an older nRF52840 MDK.

UF2 Bootloader 0.2.13-42-g82464f9-dirty lib/nrfx (v2.0.0) lib/tinyusb (legacy-1500-g23df777b) s140 6.1.1 Model: nRF52840 MDK USB Dongle Board-ID: nRF52840-Dongle-v1 Date: Feb 3 2020

I used the uf2conv tool from the MS github: https://github.com/Microsoft/uf2

python3 uf2conf.py s140_nrf52_6.1.1_softdevice.hex -c -f 0xADA52840

And just copied the output (flash.uf2) to the root directory when the MDK was in file mode (hold reset when inserting the usb)

Thanks，I will try it.
