This application note has been explicitly tested on the NXP MIMXRT1060-EVKB board, however, it should apply to the other NXP EVK boards in the i.MX RT family as well, perhaps, with some minor changes to the software.
1. Connecting MIMXRT1060-EVKB Board to the NAVQ+ Kit
...
The following hardware setup is required for installing and running a Zephyr sample on the NXP MIMXRT1060-EVKB board:
Remove jumpers J9 and J10, to disconnect the SWD signals from onboard debug circuit. These jumpers are installed by default.
Use default power selection on J40 with pins 5-6 shorted (power supply via J1).
Connect the external J-Link probe to J2, 20-pin dual-row 0.1" header.
Connect the Ethernet cable to the RJ45 connector (J43) and to the local network.
Connect a USB hub to the NAVQ+ kit.
Connect a USB cable from the USB hub to J1. The USB connector J1 is used to power the board, and provides a UART/USB bridge through the onboard debug circuit (serial console). It is important to power up the board before powering up J-Link.
Connect a USB cable from the USB hub to the J-Link probe. It is important to do so after the board has been powered up, otherwise, the J-Link probe won't be able to detect the MCU.
2. Connecting MIMXRT1060-EVKB Board to a Linux PC
The MIMXRT1060-EVKB Board can be connected to any Linux PC the same way as it is connected to the NAVQ+ kit. Note that the USB hub is not necessary if the Linux PC has more than one USB port.
3. Building Zephyr for MIMXRT1060-EVKB Board
Zephyr samples can be built as described in the Zephyr Project documentation:
...
| Code Block |
|---|
cd zephyr west build -p always -b mimxrt1060_evkb samples/hello_world |
4. Installing Zephyr on MIMXRT1060-EVKB Board from the NAVQ+ Kit
Use west to install Zephyr from the NAVQ+ Kit:
| Code Block |
|---|
user@imx8mpnavq:~/work/zephyrproject/zephyr$ west flash -- west flash: rebuilding ninja: no work to do. -- west flash: using runner jlink -- runners.jlink: JLink version: 7.92g -- runners.jlink: Flashing file: /mnt/sdcard/work/zephyrproject/zephyr/build/zephyr/zephyr.bin |
5. Installing Zephyr on MIMXRT1060-EVKB Board from a Linux PC
If the J-Link probe is directly connected to the build machine then the “west flash" command can be used to flash the sample as described in the Zephyr Project documentation:

6. Controlling MIMXRT1060-EVKB Board LEDs from the NAVQ+ Kit
Emcraft provides the simple Zephyr demo (emcraft/app/led_network_control) that allows to control the board LEDs from the NAVQ+ kit over the local network.
