i.MX 6ULL 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.

      

   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

      SPL-<machine-name>

      

2. Extract the file lmp-factory-image-imx6ullevk.wic.gz:

   gunzip lmp-factory-image-imx6ullevk.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-imx6ullevk.tar.gz:

   tar -zxvf mfgtool-files-imx6ullevk.tar.gz
   

5. Organize all the files like the tree below:

   ├── lmp-factory-image-<machine-name>.wic.gz
   ├── u-boot-<machine-name>.itb
   ├── sit-<machine-name>.bin
   ├── SPL-<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. 34 imx6ullevk

1. 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 J1901. Connect the other end of the cable to a PC acting as a host terminal. One UART connection will appear on the PC. On a Linux host for example:

   $ ls -l /dev/serial/by-id/
   total 0
   lrwxrwxrwx 1 root root 13 Dec  3 13:09 usb-Silicon_Labs_CP2102_USB_to_UART_Bridge_Controller_0001-if00-port0 -> ../../ttyUSB2
   

   Using a serial terminal program like minicom, connect to the port with if00 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 (SW2001)

3. Put the imx6ullevk into programing mode:

   Switch SW602 to boot from serial downloader by setting to OFF, ON (from 1-2 bit)

   

   Fig. 35 SW602 settings

D1/MODE1	D2/MODE0	BOOT MODE
OFF	OFF	Boot From Fuses
OFF	ON	Serial Downloader
ON	OFF	Internal Boot
ON	ON	Reserved

Switch SW601 to device microSD by setting to OFF, OFF, ON, OFF (from 1-4 bit)

D1	D2	D3	D4	BOOT MODE
OFF	OFF	ON	OFF	MicroSD
OFF	OFF	OFF	OFF	QSPI
OFF	ON	ON	OFF	EMMC
ON	ON	OFF	ON	NAND

1. Connect your computer to the EVK board via the USB OTG jack.
2. Connect the plug of the 5V power supply to the DC power jack J2001.
3. Power on the EVK board by sliding power switch SW2001 to ON.

Flashing

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

Note

For instructions on how to sign the required images before flashing them to the board with secure boot enabled, follow the instructions from Machines with secure aspects enabled by FoundriesFactory.

Linux

Windows

1. Verify target is present:

   $ lsusb | grep Freescale
   Bus 002 Device 052: ID 15a2:0080 Freescale Semiconductor, Inc.
   

   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 SW602 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 SW2001 to ON.
