# MakerDiary NRF52840 MDK
2+
3+
Refer to https://github.com/makerdiary/nrf52840-mdk or
4+
https://wiki.makerdiary.com/nrf52840-mdk/ for more details about the device.
5+
6+
Notably, CircuitPython does not currently support QSPI external flash on NRF
7+
devices, so neither does this port - the 64Mb flash device is not used for
8+
anything. Also, don't confuse this with the 64MiB drive that shows up on your
9+
computer - it's actually part of the MSC driver provided by the DAPLink
10+
debugger, and is inaccessible at all from Python land (this drive is where you
11+
can copy `firmware.hex` if you'd prefer to flash that way as opposed to with
12+
`pyocd`. You'll still have access to 256KB of the onboard flash, however, for
13+
storing your Python files, cat pictures, or whatever.
14+
15+
It's also interesting to note that all three LEDs and the "user button" on this
16+
device are wired through sinks, not sources, so flip your boolean expectations
17+
when dealing with `digitalio.DigitalInOut` on this device - `my_led.value =
18+
True` turns the LED off! Likewise, the user button will read `False` when
19+
pressed.
20+
21+
## Installing CircuitPython submodules
22+
23+
Before you can build, you will need to run the following commands once, which
24+
will install the submodules that are part of the CircuitPython ecosystem, and
25+
build the `mpy-cross` tool:
26+
27+
```
28+
$ cd circuitpython
29+
$ git submodule update --init
30+
$ make -C mpy-cross
31+
```
32+
33+
You then need to download the SD and Nordic SDK files via:
34+
35+
> This script relies on `wget`, which must be available from the command line.
36+
37+
```
38+
$ cd ports/nrf
39+
$ ./drivers/bluetooth/download_ble_stack.sh
40+
```
41+
42+
## Note about bootloaders
43+
44+
While most Adafruit devices come with (or can easily be flashed with) an
45+
Adafruit-provided bootloader (supporting niceties like UF2 flashing), this
46+
board comes with DAPLink which (apparently?) handles everything from debugging
47+
to programming the device, as well as the boot sequence. What's particularly
48+
awesome about this board is that there is no physical interaction with the board
49+
required to flash new code (read: CircuitPython builds) - the device is _always_
50+
listening for new firmware uploads (via `pyocd-flashtool`), even if userspace
51+
code is running.
52+
53+
## Building and Flashing CircuitPython
54+
55+
You'll need to have [pyocd](https://github.com/mbedmicro/pyOCD) installed as
56+
appropriate for your system.
57+
58+
```sh
59+
make BOARD=makerdiary_nrf52840_mdk FLASHER=pyocd SD=s140 flash
60+
```
61+
62+
This should give you the following (or very similar) output, and you will see
63+
a DFU blinky pattern on one of the board LEDs:
64+
65+
```
66+
$ make BOARD=makerdiary_nrf52840_mdk FLASHER=pyocd SD=s140 flash
67+
Use make V=1, make V=2 or set BUILD_VERBOSE similarly in your environment to increase build verbosity.

98+
Alternatively (and untested by me), it's apparently possible to copy
99+
`firmware.hex` to the MSC device provided by DAPLink and flash that way. Refer
100+
to [the upstream
101+
documentation](https://wiki.makerdiary.com/nrf52840-mdk/getting-started/#drag-n-drop-programming)
102+
for details.
