Add mbed disk programmer option

[sandeepmistry]

During #HackIllinois2017 @jacobrosenthal observed many issues with Windows and Zadig.

Need to explore adding a option to upload using the mbed disk using a batch file (windows) and shell script (Linux/Mac).

Rough set of steps needed:

1. Build .hex file and merge soft device. If soft device is not erased during upload we can skip the merge step.
2. Detect mbed drive location via checking drives for a MBED.htm file
3. Copy file to mbed disk drive.

I've been using the Segger upload tools instead of the current method and I find it's more reliable. All you need is the Nordic tool kit (free) and a batch file on Windows. There's no code to maintain other than the batch file. There's also the benefit of supporting normal, non-integrated Segger debug probes.

@dlabun could this approach work for Mac and Linux too?

@jacobrosenthal what do you think of this? I think the one advantage of the mbed approach is it would also work with CMSIS DAP programmers too.

Yes it would as Nordic has the tool kit for Mac and Linux as well.... They call it the Command Line Tools on the link below.

As a side note, Nordic has updated the OB-JLink firmware to rev 160914.

Id say go with the segger stuff. The mbed disk is pretty pervasive, but theres no feedback except the fail file and we dont want to be digging around in there for success/fail messages That said, license issues? Id hate to add a fourth component to download its already pretty arduous. I guess it could be bundled with the softdevice download?

As far as I can tell there shouldn't be licensing issues as the tool kit is freely available on the Nordic site, it's being used strictly on Nordic chips as intended and we wouldn't be modifying it.

Adding a fourth component is a good point... Is there a way to make it an optional part of the install? (If you want it, go grab it?)

[jacobrosenthal]

Wait, what sandeep said. The segger stuff will only work with jlink devices, and the mbed stuff is going to be cmsisdap based..

Hmm... You almost need 3 different upload methods to cover all of the tools out there. May you could do 3 different editions of the core? For example v0.3-OpenOCD, -Segger or -mbed... Only difference being the flashing tool that installed.

[jacobrosenthal]

I dont love that. If theres no licensing then just bundle the smallest subset and make it a larger download.

Well the Linux package was 770kb to download, Win32 installer was 24mb... I don't think that will be too bad

[jacobrosenthal]

I wonder if this is just a virtual serial port driver, or if it does anything with cmsisdap. Not sure we tried it this weekend. https://developer.mbed.org/handbook/Windows-serial-configuration#1-download-the-mbed-windows-serial-port

The DAP part is based on USB HID, not sure if you need a driver for it.

Should I rename this issue to something more like "Improve Windows setup"?

[jacobrosenthal]

Ill get a windows vm and see what the hell it shows up as
