i.MX 8M Plus Evaluation Kit

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.

      

   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>

      

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:

Fig. 32 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.

   

   Fig. 33 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.

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:

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.
