The board is pre-programmed with a program indicating that the target MCU is running. Connect a micro USB cable from connector J40 (LINK USB) to a host computer or supply to power up the board and run this program. The following debug probes can be used with the board: · On-board debug probe (LPC4322 Link2), Cortex® M33 only. · SEGGER J-link probes (version 9 or newer). Other debug probes may also be supported by IAR and Keil tools and by other IDEs/debug tools. See third-party websites for further information. 2.1 Starting a debug session using on-board (Link2) Debug Probe By default, the i.MX RT595 EVK is configured to use the on-board Debug Probe (Link2) via J40 to debug the on-board target (i.MX RT595), using the CMSIS-DAP debug protocol pre-programmed into the Link2 Flash memory. When connecting the USB cable, this powers the board and you see that a virtual COM port enumerates. When using the MCUXpresso IDE, the on-board Link2 can also be booted in the DFU mode (see jumper settings). If this is done, MCUXpresso IDE downloads CMSIS-DAP to the probe as needed. Using the DFU boot mode, ensure that the most up-to-date/compatible firmware image is used with MCUXpresso IDE. The IAR IDE or other development tools that support the CMSIS-DAP protocol can be used in the default configuration (once support is released for those tools). Check with your toolchain vendor for availability of specific device support packs for the i.MX RT595 series devices. NOTE If the Debug Probe is set up to boot in DFU mode, the USB bridge functions (virtual COM port) and Debug Probe features will not be available if the board is not first initialized by the MCUXpresso IDE. 2.2 Download and install the MCUXpresso SDK In order to download the RT500 SDK, visit the MCUXpresso SDK Builder site. · Go to https://mcuxpresso.nxp.com · Make sure to log in with NXP account · Click select development board · Type in "EVK-MIMXRT595" · Add desired software components · Now, download SDK 2.3 Installation steps to use with MCUXpresso IDE 1. Download and install the MCUXpresso IDE v11.3 or latest. 2. Install the RT500 SDK zip package. 3. Install JP1 to force the Link2 Debug Probe to boot in DFU mode. User's Guide MIMXRT595 EVK Board Hardware User's Guide, Rev. 0, 02/2021 6 / 35 NXP Semiconductors Getting started NOTE If the Debug Probe is set up to boot in DFU mode, the USB bridge functions (virtual COM port) and Debug Probe features will not be available if the board is not first initialized by the MCUXpresso IDE. 4. Ensure that: · The jumper JP2 is fitted in position 1-2, local target powered. · The jumper JP3 is not installed. 5. Connect the board to the USB port of your host computer, connecting a micro USB cable to connector J40 (Link USB). 6. Allow about 10 seconds for the i.MX RT595 EVK device to enumerate for the first time. The device will appear as LPC-Link2 UCom Port. Now you can use the MCUXpresso IDE to run the various SDK examples. If the first attempt to debug a project fails in the IDE, cancel the debug session and repower the board. On some machines the drivers take longer to enumerate for the first time, so these steps should correct the issue. 2.4 Installation steps to use Keil and IAR tools 1. Download and install LPCScrypt for LPCXpresso boards (http://www.nxp.com/lpcutilities). This installs required drivers for the board. NOTE The Link2 (LPC4322 device) is pre-programmed with CMSIS-DAP firmware during manufacture, so you do not need to program it. 2. Ensure that JP1 is open to force the Link2 Debug Probe to boot from internal flash. 3. Ensure that jumper JP2 is fitted in position 1-2, and JP3 is not installed. These are the default position set during board manufacture. 4. Connect the i.MX RT595 board to the USB port of your host computer, connecting a micro USB cable to connector J40 (Link USB). Allow about 10 seconds for the Link2 devices to enumerate for the first time. It is not necessary to check the Hardware Manager. Your board is now ready to use with your third-party tool. Follow the instructions for those tools for using a CMSIS-DAP probe. MCUXpresso IDE can also be used with the board after setting up the board this way. Now, you can use the Keil/IAR IDE to run the various SDK examples. NOTE If using IAR, use v8.50.9 or latest. If using Keil, use v.5.33 or latest. 2.5 Starting a debug session using external Debug Probe The i.MX RT595 target can also be programmed and debugged using an external Debug Probe that conforms to the standard Arm® Cortex-M debug connectors (either with 10 pin or 20 pin). To use an external Debug Probe, connect the probe to one of the SWD connectors (J2 or J19) and connect power via the micro USB connector J39. User's Guide MIMXRT595 EVK Board Hardware User's Guide, Rev. 0, 02/2021 7 / 35 NXP Semiconductors Chapter 3 On-board (Link2) debug probe This section describes the features provided by the on-board Link2 Debug Probe, including how to use this to debug an external target. The Link2 Debug Probe is implemented using an LPC43xx MCU, which provides a high-speed USB port interface to the host computer that runs the development tools. This device is not intended for developer use, and should only be used with approved firmware images from NXP. The Link2 on-chip flash memory is factory programmed with a firmware image that supports CMSIS-DAP debug protocol, but also includes other USB end-point functions. · Virtual COM (VCOM) port: a serial device that can be used with any host computer application design for serial port communication (for example, Teraterm, puTTY). Set the terminal program for baud rate to 115200, no parity, 8-bit data, 1 stop bit, no flow control. · SWO trace end point: this virtual device is used by MCUXpresso to retrieve SWO trace data. See the MCUXpresso IDE documentation for more information. All of these devices are independent of each other and of the CMSIS-DAP debug device that is enumerated when the board is connected to a host computer; for example, the VCOM port can be used if the board is running an application when no debugger is running. In order to correctly install and use the Link2 device on the i.MX RT595 EVK (required for any debugging purpose) for Windows 7 or 8 host computers, install the drivers first. These drivers will automatically be installed when MCUXpresso IDE has already been installed. If these IDEs are not being used, it is recommended LPCScrypt be installed as this also includes the required drivers. All these tools and utilities are available for free download at https://www.nxp.com/lpcscrypt. The CMSIS-DAP firmware image installed at the factory (and by LPCScrypt) will uniquely identify itself to the host computer so that more than one board can be connected to that host computer at any time. Some toolchains cannot discern between multiple debug devices, see your toolchain documentation for more information. NOTE MCUXpresso does support multiple LPCXpresso board targets. It is strongly recommended that LPCScrypt be used to update the Debug Probe firmware in order to ensure that the latest version is being used. NOTE The Link2 only boots when the board is power cycled; the reset button on the board does not reset the Link2. When using MCUXpresso IDE, the Link2 can be automatically booted with the latest / most appropriate firmware for that IDE version by installing JP1 DFU jumper before powering up the board. This is the recommended approach for the MCUXpresso IDE. NOTE If JP1 is installed when powering the board, then the VCOM port (and other devices mentioned above) device will not appear until the MCUXpresso IDE boots the Debug Probe. The Debug Probe is booted once a debug session is started (that is, the IDE attempts to download code to the target). 3.1 Programming the Link2 firmware As mentioned earlier in this section, it is not normally necessary to program the Link2 firmware. However, this can easily be accomplished using the supporting utility, LPCScrypt. To program the Link2 flash, the Link2 device (LPC432x) must be in DFU mode. If the Link2 already has a valid image in the flash, it needs to be forced into DFU mode by placing a jumper shunt on JP1, and power cycling (disconnecting then reconnecting power). Link2 MCU programming is performed using the LPCScrypt utility (see http://www.nxp.com/lpcscrypt). Instructions for using the tool are located at the same webpage. You can also check the instructions in the RT500 Get Started Guide. User's Guide MIMXRT595 EVK Board Hardware User's Guide, Rev. 0, 02/2021 8 / 35 NXP Semiconductors On-board (Link2) debug probe 3.2 VCOM port The identifier of the VCOM port varies between boards and hosts as each board enumerate with a unique identifier. On Windows OS, to determine the COM port, open the Windows operating system Device Manager. This can be achieved by going to the Windows operating system click on Start menu and typing Device Manager in the search bar. In the device manager look under "Ports"; the LPC-LinkII UCom Port device and its name should be visible. This VCOM port will only appear: NOTE · If the Debug Probe has been programmed with the CMSIS-DAP firmware and the Debug Probe DFU link (JP1) is removed at power-up. · If the Debug Probe has been configured for DFU boot (JP1) installed at power-up and MCUXpresso IDE has booted it (by starting a debug session).

The voltage supplied can be measured on TP42 (SWI1_OUT output voltage from PMIC). GPIO current supplies can be measured via JS20 (VDDIO_0), JS21 (VDDIO_1), JS22 (VDDIO_2), JS23 (VDDIO_3), and JS24 (VDDIO_4). Other headers to measure power are JS29 (VDD_AO) and JS30 (VDD1V8). For further details, see board schematics. 5.2 PMIC (PCA9420UK) The MIMXRT595 EVK includes a discrete Power Management Integrated Circuit (PMIC) converter. Using the PMIC adds flexibility to configure the power supply rails according to the needs of the application. This converter provides all required supplies to all circuitry except the debug probe. The PMIC has four output voltages, SW1_OUT, SW2_OUT, LDO1_OUT, LDO2_OUT. Table 4.
