i.MX 8MQuad Evaluation Kit¶

Preparation¶

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

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

Click the latest Target with the platform-devel trigger.
Expand the run in the Runs section (by clicking on the + sign) 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

and: imx-boot-<machine_name>
Extract the file lmp-factory-image-<machine_name>.wic.gz:
```
gunzip lmp-factory-image-<machine_name>.wic.gz
```
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: <machine_name>-mfgtools
Download and extract the file mfgtool-files-<machine_name>.tar.gz:
```
tar -zxvf mfgtool-files-<machine_name>.tar.gz
```

Organize all the files like the tree below:

├── imx-boot-<machine_name>
├── lmp-factory-image-<machine_name>.wic
└── 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:

OPTIONAL - Only required if you have a problems and/or want to see the boot console output.
Connect the micro-B end of the USB cable into debug port J1701. Connect the other end of the cable to a PC acting as a host terminal. Two 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 Nov 16 23:45 usb-Silicon_Labs_CP2105_Dual_USB_to_UART_Bridge_Controller_007FC3F4-if00-port0 -> ../../ttyUSB0 lrwxrwxrwx 1 root root 13 Nov 16 23:45 usb-Silicon_Labs_CP2105_Dual_USB_to_UART_Bridge_Controller_007FC3F4-if01-port0 -> ../../ttyUSB2
Using a serial terminal program like minicom, connect to the port with if00 in the name (in this example ttyUSB0) and apply the following configuration
Baud rate: 115200

Data bits: 8

Stop bit: 1

Parity: None

Flow control: None
Ensure that the power is off (SW701)
Put the imx8mqevk into programing mode:

Switch SW801 to OFF, OFF, ON, OFF (from 1-4 bit) to boot from the eMMC.

Switch SW802 to boot from serial downloader by setting to OFF, ON (from 1-2 bit)
Connect your computer to the EVK board via the USB Type-C jack.
Connect the plug of the 12V power supply to the DC power jack J902.
Power on the EVK board by sliding power switch SW701 to ON.

Flashing¶

Note

Removing the power plug will not power off the board if the USB-C cable is still connected.

Note

USB-C may power the board but it is not sufficient to power the board during run time and intermittent failures will occur.

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

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.

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

Turn off the power.
Put the board into run mode

Start the Device Manager
Select View
Select Devices by container
Verify a device like the following:

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

Turn off the power.
Put the board into run mode

To put the EVK into run mode, switch SW802 to internal boot by setting to ON, OFF (from 1-2bit). This is the opposite of programming mode described previously.

Power on the EVK board by sliding power switch SW701 to ON.
