SOM-Trizeps-VIII-MX8M-Plus (Trizeps 8 Plus)

This page contains the instructions to flash the eMMC/internal SSD on a SOM-Trizeps-VIII-MX8M-Plus (Trizeps 8 Plus) SECO board. If your module configuration has a MicroSD slot as a default storage, please refer to Installation on an External Storage. This board flashing procedure follows the generic instructions, with some additional steps.

info

The instructions provided below refers to the usage of UUU tool under Linux OS, the same instructions can be applied to Windows starting from uuu.exe executable.

Software Requirements​

Apart from the tools necessary (see NXP SOC Flashing page), the user needs to download in the same folder where UUU is present:

  • Image (wic.bz2)
  • U-Boot (u-boot.tar.gz)

Instructions​

These are the instruction to be followed in order to flash Clea OS on device eMMC/internal SSD considering the module inserted on pConXS III Carrier:

  • Decompress the .wic.bz2 image file, e.g. using $ bzip2 -d <image_name>.wic.bz2.

  • Decompress the .tar.gz U-Boot file, e.g. using $ tar -xzvf <uboot_name>.tar.gz.

  • Make sure both jumpers near the USB ports are set to "OTG".

  • Carrier-Trizeps-pConXS-III does not have a dedicated switch to enter the Download Mode, so:

  • Stop the boot in U-Boot by pressing ESC button.

    • If the module has the MCU placed, run the following command to reboot the module into Download Mode: 
      > i2c dev 2; i2c mw 0x10 2.1 2; reset
    • If the module has the MCU not placed, run the following command to erase the old bootloader and reboot the module into Download Mode: 
      > mmc partconf 0 1 0 1; mmc erase 1 100; mmc partconf 0 1 1 1; mmc erase 1 100; mmc partconf 0 0 0 0; mmc erase 1 100; reset

  • Connect the USB type-A to USB type-A cable to the lower port of dual-USB connector of pConXS III carrier board on one side but wait to connect the other side to the Host PC.

  • Power on the pConXS III carrier board.

  • Start flashing the image on the SOM-Trizeps-VIII-MX8M-Plus device via the following command:

$ sudo ./uuu -b emmc_all <file_path_of_boot_loader> <file_path_of_image_file>

  • Connect the USB type-A connector of the cable to the Host PC.

  • Check that the flashing procedure starts and proceeds without errors,

  • You can check the output of the serial debug port (e.g. via minicom) connecting the serial cable to RS232 port of pConXS III carrier board.

  • Once the flashing procedure has finished, reboot the board by power cycling the pConXS III carrier board.
