i.MX 8M Plus Evaluation Kit

Note

The instructions in this section also applies to those boards with secure boot enabled. There are references on how to perform common instructions along with the flow.

The Security Reference Manual details the required background for secure boot.

Preparation

Ensure you replace the <factory> placeholder below with the name of your Factory.

  1. Download necessary files from https://app.foundries.io/factories/<factory>/targets

    1. Click the latest Target with the platform-devel Trigger.

      ../../_images/generic-steps-1.png

    2. Expand the run in the Runs section which corresponds with the name of the board and download the Factory image for that machine.

      E.g:
      lmp-factory-image-<machine-name>.wic.gz
      u-boot-<machine-name>.itb
      sit-<machine-name>.bin
      imx-boot-<machine-name>
      ../../_images/imx-steps-2.png

  2. Extract the file lmp-factory-image-<machine-name>.wic.gz:

    gunzip lmp-factory-image-<machine-name>.wic.gz

  3. Expand the run in the Runs section which corresponds with the name of the board mfgtool-files and download the tools for that machine.

    E.g: mfgtool-files-<machine-name>.tar.gz

  4. Download and extract the file mfgtool-files-<machine-name>.tar.gz:

    tar -zxvf mfgtool-files-<machine-name>.tar.gz

  5. Organize all the files like the tree below:

    ├── lmp-factory-image-<machine-name>.wic
├── u-boot-<machine-name>.itb
├── sit-<machine-name>.bin
├── imx-boot-<machine-name>
└── mfgtool-files-<machine-name>
      ├── bootloader.uuu
      ├── full_image.uuu
      ├── imx-boot-mfgtool
      ├── uuu
      └── uuu.exe

Hardware Preparation

Set up the board for updating using the manufacturing tools:

../../_images/imx8mp-lpddr4-evk.png

Fig. 59 imx8mp-lpddr4-evk

  1. OPTIONAL - Only required if you have problems and/or want to see the boot console output.

    Connect the micro-B end of the USB cable into debug port J23. Connect the other end of the cable to a PC acting as a host terminal. Four UART connections will appear on the PC. On a Linux host for example:

    $ ls -l /dev/serial/by-id/
total 0
lrwxrwxrwx 1 root root 13 jan 24 10:24 usb-FTDI_Quad_RS232-HS-if00-port0 -> ../../ttyUSB0
lrwxrwxrwx 1 root root 13 jan 24 10:24 usb-FTDI_Quad_RS232-HS-if01-port0 -> ../../ttyUSB1
lrwxrwxrwx 1 root root 13 jan 24 10:24 usb-FTDI_Quad_RS232-HS-if02-port0 -> ../../ttyUSB2
lrwxrwxrwx 1 root root 13 jan 24 10:24 usb-FTDI_Quad_RS232-HS-if03-port0 -> ../../ttyUSB3

    Using a serial terminal program like minicom, connect to the port with if02 in the name (in this example ttyUSB2) and apply the following configuration

    • Baud rate: 115200
    • Data bits: 8
    • Stop bit: 1
    • Parity: None
    • Flow control: None

  2. Ensure that the power is off (SW3)

  3. Put the imx8mp-lpddr4-evk into programing mode:

    Switch SW4 to OFF, OFF, OFF, ON (from 1-4 bit) as shown below.

    ../../_images/imx8mp-lpddr4-evk_SW.png

    Fig. 60 SW4 programing settings

  4. Connect your computer to the EVK board via the USB Type-C port 1 Download J6 jack.

  5. Connect the USB Type-C power plug to the port 2 Power J5 jack.

  6. Power on the EVK board by sliding power switch SW3 to ON.

Flashing

Once in serial downloader mode and connected to your PC the evaluation board should show up as an NXP USB device.

Linux
Windows

  1. Verify target is present:

    $ lsusb | grep NXP
Bus 001 Device 023: ID 1fc9:012b NXP Semiconductors i.MX 8M Dual/8M QuadLite/8M Quad Serial Downloader

    In this mode you will use the uuu tools to program the images to the eMMC. The USB ID may differ if a different SoC is used.

  2. Run the command below to program the LmP to the EMMC:

    $ sudo mfgtool-files-<machine-name>/uuu -pp 1 mfgtool-files-<machine-name>/full_image.uuu
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.4.43-0-ga9c099a

Success 1    Failure 0


1:31     3/ 3 [=================100%=================] SDPV: jump
2:31     8/ 8 [Done                                  ] FB: done

  3. Turn off the power.

  4. Put the board into run mode

  1. Start the Device Manager
  2. Select View
  3. Select Devices by container
  4. Verify a device like the following:
../../_images/windows_verify.png

  1. Run the command below to program the LmP to the EMMC:

    C:\Users\Someone> mfgtool-files-<machine-name>\uuu.exe -pp 1 mfgtool-files-<machine-name>\full_image.uuu
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.4.43-0-ga9c099a

Success 1    Failure 0


1:31     3/ 3 [=================100%=================] SDPV: jump
2:31     8/ 8 [Done                                  ] FB: done

  2. Turn off the power.

  3. Put the board into run mode

To put the EVK into run mode, switch SW3 to eMMC setting (OFF, OFF, ON, OFF).

Power on the EVK board by sliding power switch SW3 to ON.
