Supported Features
The mimxrt1015_evk board configuration supports the hardware features listed below. For additional features not yet supported, please also refer to the MIMXRT1064-EVK , which is the superset board in NXP’s i.MX RT10xx family. NXP prioritizes enabling the superset board with NXP’s Full Platform Support for Zephyr. Therefore, the mimxrt1064_evk board may have additional features already supported, which can also be re-used on this mimxrt1015_evk board:

System Clock
The MIMXRT1015 SoC is configured to use SysTick as the system clock source, running at 500MHz.
When power management is enabled, the 32 KHz low frequency oscillator on the board will be used as a source for the GPT timer to generate a system clock. This clock enables lower power states, at the cost of reduced resolution
Serial Port
The MIMXRT1015 SoC has four UARTs. LPUART1 is configured for the console,
and the remaining are not used.
Programming and Debugging
This board supports 3 debug host tools. Please install your preferred host tool, then follow the instructions in Configuring a Debug Probe to configure the board appropriately.
LinkServer Debug Host Tools (Default, Supported by NXP)
J-Link Debug Host Tools (Supported by NXP)
pyOCD Debug Host Tools (Not supported by NXP)
Once the host tool and board are configured, build and flash applications as usual (see Building an Application and Run an Application for more details).
Configuring a Debug Probe
For the RT1015, J47/J48 are the SWD isolation jumpers, J42 is the DFU mode jumper, and J34 is the 10 pin JTAG/SWD header.
A debug probe is used for both flashing and debugging the board. This board has an LPC-LINK2 Onboard Debug Probe. The default firmware present on this probe is the LPC-Link2 DAPLink Onboard Debug Probe.
Based on the host tool installed, please use the following instructions to setup your debug probe:
LinkServer Debug Host Tools: Using CMSIS-DAP with LPC-Link2 Probe
pyOCD Debug Host Tools: Using CMSIS-DAP with LPC-Link2 Probe
Using CMSIS-DAP with LPC-Link2 Probe
Follow the instructions provided at LPC-LINK2 CMSIS DAP Onboard Debug Probe to reprogram the default debug probe firmware on this board.
Ensure the SWD isolation jumpers are populated
Using J-Link with LPC-Link2 Probe
There are two options: the onboard debug circuit can be updated with Segger J-Link firmware, or a J-Link External Debug Probe can be attached to the EVK.
To update the onboard debug circuit, please do the following:
Switch the power source for the EVK to a different source than the debug USB, as the J-Link firmware does not power the EVK via the debug USB.
Follow the instructions provided at LPC-Link2 J-Link Onboard Debug Probe to reprogram the default debug probe firmware on this board.
Ensure the SWD isolation jumpers are populated.
To attach an external J-Link probe, ensure the SWD isolation jumpers are removed, then connect the probe to the external JTAG/SWD header
Configuring a Console
Regardless of your choice in debug probe, we will use the OpenSDA microcontroller as a usb-to-serial adapter for the serial console. Check that jumpers J45 and J46 are on (they are on by default when boards ship from the factory) to connect UART signals to the OpenSDA microcontroller.
Connect a USB cable from your PC to J41.
Use the following settings with your serial terminal of choice (minicom, putty, etc.):
Speed: 115200
Data: 8 bits
Parity: None
Stop bits: 1
Flashing
Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b mimxrt1015_evk samples/hello_world
west flash
Open a serial terminal, reset the board (press the SW9 button), and you should see the following message in the terminal:
***** Booting Zephyr OS v1.14.0-rc1-1297-g312d75f2459e *****
Hello World! mimxrt1015_evk
