Step 1: Install Dependencies

sudo apt-get update
sudo apt-get install libusb-1.0-0-dev

Step 2: Download uuu

Option A: Download Pre-built Binary (Recommended)

wget https://github.com/nxp-imx/mfgtools/releases/download/uuu_1.5.125/uuu
chmod a+x uuu
sudo mv uuu /usr/local/bin/

Step 3: Setup USB Permissions (Optional but Recommended)

Create udev rules to allow non-root access:

sudo sh -c 'cat > /etc/udev/rules.d/99-uuu.rules << EOF
# NXP i.MX boards in Serial Download Protocol (SDP) mode
SUBSYSTEM=="usb", ATTRS{idVendor}=="1fc9", ATTRS{idProduct}=="0146", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="1fc9", ATTRS{idProduct}=="012b", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="15a2", ATTRS{idProduct}=="0054", MODE="0666"
EOF'

sudo udevadm control --reload-rules
sudo udevadm trigger

Step 4: Verify Installation

uuu -version

Expected output:
