The IMXRT600 support 2 different pins for SWO:
The RT600 does not come with internal flash but with external flash connected to the FlexSPI bus, only. The external FlexSPI controller allows to connect several different flash types like QSPI, HyperFlash and Octaflash. Furthermore, the external flash can be connected to different pin / ports of the FlexSPI controller which makes a auto-detection very difficult thus a out-of-the-box solution which works for all setups is kind of impossible. For that reason, the J-Link software supports the evaluation board setup, only. Other setups may work but without any warranty or guarantee from SEGGER. If you are working with a different setup and looking for support for this setup, please get in touch with SEGGER.

This article covers the NXP i.MXRT600 MCU family devices.

Tracing on i.MXRT600 series

This section describes how to get started with trace on the NXP i.MXRT600 MCUs. This section assumes that there is already a basic knowledge about trace in general (what is trace, what different implementations of trace are there, etc.). If this is not the case, we recommend to read Trace chapter in the J-Link User Manual (UM08001).

Note:

  • The sample projects come with a pre-configured project file for Ozone that runs out-of-the box.
  • The following sample project is designed to be used with J-Trace PRO for streaming trace and Ozone to demonstrate streaming trace.
  • In order to rebuild the sample project, SEGGER Embedded Studio can be used. The recommended version to rebuild the projects is ES V6.30. But the examples are all pre-build and work out-of-the box with Ozone, so rebuilding is not necessary.
  • All examples are shipped with a compiled .JLinkScriptfile (.pex), should you need the original source, please get in touch with SEGGER directly via our support system: https://www.segger.com/ticket/.

Tracing on NXP i.MXRT685S

Minimum requirements

In order to use trace on the NXP i.MXRT685S MCU devices, the following minimum requirements have to be met:

  • J-Link software version V6.80d or later
  • Ozone V3.20b or later (if streaming trace and / or the sample project from below shall be used)
  • J-Trace PRO for Cortex-M HW version V1.0 or later for streaming trace

To rebuild the project our IDE Embedded Studio can be used. The recommended version to rebuild the projects is V6.30. But the examples are all prebuild and work out-of-the box with Ozone, so rebuilding is not necessary.

Streaming trace

The project has been tested with the minimum requirements mentioned above and a NXP MIMXRT685-EVK.

Example project RAM: NXP_iMXRT685_Trace_Example.zip

The RAM trace example should run on any NXP iMXRT685S platform.


Example project QSPI: NXP_IMXRT685_QSPI_TracePins.zip

The QSPI Flash trace sample may only run on boards that use the same components as the mentioned eval board below. You can find the Ozone project file (.jdebug) under the following path in the sample: /Start/BoardSupport/NXP/iMXRT685S_MIMXRT685_EVK

Tested Hardware

NXP MIMXRT685-EVK

Reference trace signal quality

The following pictures show oscilloscope measurements of trace signals output by the "Tested Hardware" using the example project. All measurements have been performed using a Agilent InfiniiVision DSO7034B 350 MHz 2GSa/s oscilloscope and 1156A 1.5 GHz Active Probes. If your trace signals look similar on your trace hardware, chances are good that tracing will work out-of-the-box using the example project. More information about correct trace timing can be found at the following website.

Trace clock signal quality

The trace clock signal quality shows multiple trace clock cycles on the tested hardware as reference.

Trace clock signal quality
Rise time

The rise time of a signal shows the time needed for a signal to rise from logical 0 to logical 1. For this the values at 10% and 90% of the expected voltage level get used as markers. The following picture shows such a measurement for the trace clock signal.

TCLK rise time
Setup time

The setup time shows the relative setup time between a trace data signal and trace clock. The measurement markers are set at 50% of the expected voltage level respectively. The following picture shows such a measurement for the trace data signal 0 relative to the trace clock signal.

TD0 setup time

SWO on i.MXRT600 series

The IMXRT600 support 2 different pins for SWO:

Pin function
PIO2_24 FUNC 1
PIO2_31 FUNC 5

For PIO2_24 SWO support is available out-of-the-box for version V6.84 and later. The following SEGGER Embedded Studio Project comes with a compiled J-Link Script file (.pex) used for the initialization of SWO via PIO2_24.

Sample Projects

QSPI support

The RT600 does not come with internal flash but with external flash connected to the FlexSPI bus, only. The external FlexSPI controller allows to connect several different flash types like QSPI, HyperFlash and Octaflash. Furthermore, the external flash can be connected to different pin / ports of the FlexSPI controller which makes a auto-detection very difficult thus a out-of-the-box solution which works for all setups is kind of impossible. For that reason, the J-Link software supports the evaluation board setup, only. Other setups may work but without any warranty or guarantee from SEGGER. If you are working with a different setup and looking for support for this setup, please get in touch with SEGGER via our support system: https://www.segger.com/ticket/.

NOTE: The BOOT ROM of the RT600 seems to activate the octa mode under some circumstances. In order to bring the flash into a proper / known state, the J-Link flashloader resets the QSPI flash using the nRESET pin of the flash which is connected to PIO2_12 on the evaluation board.

FlexSPI A

nRESET_QSPI PIO2_12 PIO2_12

NOTE: The BOOT ROM of the RT600 seems to activate the octa mode under some circumstances. In order to bring the flash into a proper / known state, the J-Link flashloader resets the QSPI flash using the nRESET pin of the flash which is connected to PIO2_12 on the evaluation board.

Example Application

The application toggles 3 LEDs (blue, red and green) on the MIMXRT685-EVK evaluation board. The application is linked into the external flash (connected to FlexSPI port B). It includes a valid boot header so it also runs stand-alone.
