On Linux systems, connect the serial cable from the board to the host computer.
Connect also the Micro USB cable from the micro USB connector of the board to the host computer to use fastboot. A USB 2.0 cable is recommended, as U-Boot could have some issues with USB 3.0 cable.
Then, enter fastboot mode on the Nitrogen8M Mini board:
- From U-Boot prompt, enter the following command:
=> fastboot 0
From the Host PC:
$ unzip BoundaryDevices_Nitrogen8MM-AndroidOS-p9.0.0_1.0.0-ga-dev-1.0-SNAPSHOT-[date].zip -d nitrogen8mm_p900 $ cd nitrogen8mm_p900 nitrogen8mm_p900$ sudo ./flash_fastboot.sh
After the reboot, enter fastboot mode again and update U-Boot. This is necessary to get ADB working: From the U-Boot prompt:
=> run upgradeu
