Index of the Moto Mods Developer project:
With your Moto Z Droid plugged in and on file transfer mode, Navigate to the second nuttx folder, right click and ‘Copy To…’
Select phone name and save it in the Phone’s Downloads folder
On the phone, launch MDK Utility app.
In Developer Mode, Select files→ nuttx.tftf
Hit “PERFORM UPDATE”
If prompted, click continue.
The firmware name will show “MDK-RAWBLINKY” as we named in the Hardware Manifests file.
NOTE: For some reason the MDK Utility app from the app store doesn’t let you switch back to “SET MODE” once your custom firmware is loaded. The only way to use the “MDK LED Light” switch in the app is to be in SET MODE. The switch is always greyed out in DEVELOPER MODE.
The way around this: On github, in the MotorolaMobilityLLC repository, there is an mdkutility which is a different version that does not have modes in its APK. Download and install this APK. Load the “MDK-RAWBLINKY” firmware with the app store version of MDK Utility. Then switch to the repository APK. This will allow you to use the “MDK LED Light” switch with your custom firmware. Now the firmware should blink the LED soldered to the test point PG10. Turning the switch ON will start the blinking.
There you go….success. Custom blinky firmware using Moto Mods with perfboard.
