Only the first 16K of ocram2 has the correct MPU region attributes set to be used as shared memory
System Clock
The MIMXRT1170 SoC is configured to use SysTick as the system clock source, running at 996MHz. When targeting the M4 core, SysTick will also be used, running at 400MHz
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 MIMXRT1170 SoC has 12 UARTs. LPUART1 is configured for the console,
LPUART2 for the Bluetooth Host Controller Interface (BT HCI), and the
remaining are not used.
Fetch Binary Blobs
The board Bluetooth/WiFi module requires fetching some binary blob files, to do that run the command:
west blobs fetch hal_nxp
Note
Only Bluetooth functionality is currently supported.
Programming and Debugging
Build and flash applications as usual (see Building an Application and Run an Application for more details).
Building a Dual-Core Image
Dual core samples load the M4 core image from flash into the shared ocram
region. The M7 core then sets the M4 boot address to this region. The only
sample currently enabled for dual core builds is the openamp sample.
To flash a dual core sample, the M4 image must be flashed first, so that it is
written to flash. Then, the M7 image must be flashed. The openamp sysbuild
sample will do this automatically by setting the image order.
The secondary core can be debugged normally in single core builds
(where the target is mimxrt1170_evk/mimxrt1176/cm4). For dual core builds, the
secondary core should be placed into a loop, then a debugger can be attached
(see AN13264, section 4.2.3 for more information)
Configuring a Debug Probe
A debug probe is used for both flashing and debugging the board. The on-board debugger listed below works with the LinkServer runner by default, or can be reprogrammed with JLink firmware.
MIMXRT1170-EVKB: MCU-Link CMSIS-DAP Onboard Debug Probe
MIMXRT1170-EVK: OpenSDA DAPLink Onboard Debug Probe
Using J-Link
JLink is the default runner for this board. Install the J-Link Debug Host Tools and make sure they are in your search path.
There are two options: the onboard debug circuit can be updated with Segger J-Link firmware, or J-Link External Debug Probe can be attached to the EVK. See Using J-Link with MIMXRT1170-EVKB or Using J-Link with MIMXRT1160-EVK or MIMXRT1170-EVK for more details.
Using LinkServer
Install the LinkServer Debug Host Tools and make sure they are in your search path. LinkServer works with the default CMSIS-DAP firmware included in the on-board debugger.
Use the -r linkserver option with West to use the LinkServer runner.
west flash -r linkserver
Alternatively, pyOCD can be used to flash and debug the board by using the
-r pyocd option with West. pyOCD is installed when you complete the
Get Zephyr and install Python dependencies step in the Getting Started Guide. The runners supported
by NXP are LinkServer and JLink. pyOCD is another potential option, but NXP
does not test or support the pyOCD runner.
Configuring a Console
We will use the on-board debugger microcontroller as a usb-to-serial adapter for the serial console. The following jumper settings are default on these boards, and are required to connect the UART signals to the USB bridge circuit:
MIMXRT1170-EVKB: JP2 open (default)
MIMXRT1170-EVK: J31 and J32 shorted (default)
Connect a USB cable from your PC to the on-board debugger USB port:
MIMXRT1170-EVKB: J86
MIMXRT1170-EVK: J11
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.
Before powering the board, make sure SW1 is set to 0001b
# From the root of the zephyr repository
west build -b mimxrt1170_evk/mimxrt1176/cm7 samples/hello_world
west flash
Power off the board, and change SW1 to 0010b. Then power on the board and open a serial terminal, reset the board (press the SW4 button), and you should see the following message in the terminal:
***** Booting Zephyr OS v3.4.0-xxxx-xxxxxxxxxxxxx *****
Hello World! mimxrt1170_evk
Debugging
Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b mimxrt1170_evk/mimxrt1176/cm7 samples/hello_world
west debug
Open a serial terminal, step through the application in your debugger, and you should see the following message in the terminal:
***** Booting Zephyr OS v3.4.0-xxxx-xxxxxxxxxxxxx *****
Hello World! mimxrt1170_evk
ENET1G Driver
Current default of ethernet driver is to use 100M Ethernet instance ENET.
To use the 1G Ethernet instance ENET1G, include the overlay to west build with
the option -DEXTRA_DTC_OVERLAY_FILE=nxp,enet1g.overlay instead.
