i.MX 8 ULP 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

      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.gz
   ├── u-boot-<machine-name>.itb
   ├── imx-boot-<machine-name>
   └── mfgtool-files-<machine-name>
       ├── bootloader.uuu
       ├── full_image.uuu
       ├── SPL-mfgtool
       ├── u-boot-mfgtool.itb
       ├── uuu
       └── uuu.exe
   

Hardware Preparation

Set up the board for updating using the manufacturing tools:

Fig. 85 i.MX 8 ULP 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 J17. Connect the other end of the cable to a PC acting as a host terminal. Three 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 Feb 13 12:59 usb-0403_FT4232H_9266A2-if00-port0 -> ../../ttyUSB0
   lrwxrwxrwx 1 root root 13 Feb 13 12:59 usb-0403_FT4232H_9266A2-if02-port0 -> ../../ttyUSB2
   lrwxrwxrwx 1 root root 13 Feb 13 12:59 usb-0403_FT4232H_9266A2-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 (SW10)

3. Put the i.MX 8 ULP EVK into programing mode:

   Switch SW5 to X, X, X, X, X, X, ON, OFF (from 1-8 bit) to Download Mode.

   

   Fig. 86 SW5 programing settings

4. Connect your computer to the i.MX 8 ULP EVK board via the USB Type-C port 1 Download J15 jack.

5. Connect the USB Type-C power plug to the port 2 Power SW10 jack.

6. Power on the i.MX 8 ULP EVK board by sliding power switch SW10 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:

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 i.MX 8 ULP EVK into run mode by switching SW5 to OFF, OFF, X, X, OFF, OFF, OFF, ON to set Cortex-A to boot from eMMC.

Power on the i.MX 8 ULP EVK board by sliding power switch SW10 to ON.
