¶ (Once) Build & install nxp-imx/mfgtools
- Install dependencies
sudo apt-get install libusb-1.0-0-dev libbz2-dev libzstd-dev pkg-config cmake libssl-dev g++ zlib1g-dev libtinyxml2-dev
- Build & install
uuu
cd /tmp
git clone --recursive https://github.com/nxp-imx/mfgtools && cd mfgtools
mkdir build && cd build
cmake .. && make
sudo make install
¶ Preparation
- Insert a unpowered Arduino Portenta X8 into the Pika Spark and locate the bottom-mounted DIP switches used for alternating between bootloader and application.
Fig. 1: DIP switches for selecting between application and bootloader
- Set both DIP switches for booting the bootloader on power-up (DIP switches to ON position).
Fig. 2: DIP switch selection for bootloader
- Connect the Arduino Portenta X8 USB-C connector with your PC. A “SE Blank M845S” device will be enumerated (
dmesg -wH).

¶ Flash image
- Flash image using
uuu:
cd $YOCTO_DIR/bld-xwayland
uuu -b emmc_all tmp/deploy/images/portenta-x8/pika-spark-base-image-portenta-x8.rootfs.wic.zst
Note: Ensure that the appropriate udev rules have been installed (once):
git clone https://github.com/pika-spark/pika-spark-udev
sudo cp pika-spark-udev/99-uuu.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules
sudo udevadm trigger
- After flashing disconnect the USB-C connector of the Portenta X8 (power-down) and set the DIP switches for booting the application on power-up (DIP switches to “OFF” position).

- Connect the Portenta X8 USB-C connector with your PC. A “Portenta X8” device will be enumerated (
dmesg -wH).

¶ Log-in via USB-C and adb
- Log into your image using
adb:
sudo apt-get install adb
adb shell
- Set the terminal emulator to
xtermand resize your terminal for best representation:
export TERM=xterm
resize
