¶ Linux
¶ Prepare
-
Linux image support SDcard or EMMC bootup
-
It’s recommended to use A1 rated cards, 8GB at least.
-
M2 Ultra and M2 Berry are compatiable with same Linux image.
-
Install bpi-tools on your Linux PC(if flash image with other tools, ignore this step). If you can’t access this URL or any other install problem, please go to bpi-tools source repo, download and install this tools manually.
$ apt-get install pv $ curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash -
Download latest Linux Image, and confirm that the md5 checksum is correct.
-
Default login: pi/bananapi or root/bananapi
¶ Install Image to SDcard
Windows PC
Install Image with Balena Etcher.
Balena Etcher is an opensource GUI flash tool by Balena, Flash OS images to SDcard or USB drive.
-
Click on "Flash from file" to select image.
-
Click on "Select target" to select USB device.
-
Click on "Flash!" Start burning.
Linux PC
There are two methods for you to choose from.
-
Install Image with dd command on Linux, umount SDcard device /dev/sdX partition if mounted automatically. Actually bpi-copy is the same as this dd command.
$ sudo apt-get install pv unzip $ sudo unzip -p xxx-bpi-m2-ultra-xxx.img.zip | pv | dd of=/dev/sdX bs=10M status=noxfer -
Install image with bpi-tools on Linux, plug SDcard to Linux PC and run
$ sudo apt-get install pv unzip $ sudo bpi-copy xxx-bpi-m2-ultra-xxx.img.zip /dev/sdX
¶ Install Image to eMMC
-
Prepare a SDcard with Linux image flashed and bootup board with this SDcard.
-
Unzip the image and copy it to a USB drive, plug the udisk to board and mount it.（If automatically mounted, ignore this step）
mount /dev/sdx /mnt -
There are two ways to install the linux image to board.
-
Install with dd command.
sudo dd if=/mnt/xxx.bpi-m2-ultra-xxx.img of=/dev/mmcblk0 bs=10M status=noxfer -
Install the linux image in udisk with bpi-tools command
$ sudo bpi-copy xxx-bpi-m2-ultra-xxx.img.zip /dev/mmcblk0
-
-
After download complete, power off safely and eject the SDcard.
¶ Advanced Development
¶ How to build uboot & kernel
Install tools
apt-get udpate
apt-get install gcc-arm-linux-gnueabihf u-boot-tools
apt-get install pv
curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bashClone code
git clone: https://github.com/BPI-SINOVOIP/BPI-M2U-bsp.git
./build.sh¶ SATA
-
Mount SATA on M2U
After insert sata interface, execute
fdisk -l
Then
mount /dev/sdx /mnt/xxx -
If you meet some errors when you mount SATA, try these following commands:
-
Create new partition
fdisk /dev/sdxset your partition numbers and size, after created partitions, input “wq” to save and quit.
-
Format the SATA
mkfs.ext2 /dev/sdx -
Mount
mount /dev/sdx /mnt/xxx
-
-
After you success to insert SATA, we could input following commands to test SATA interface:
-
Test read speed
time dd if=/dev/xxx of=/dev/null bs=1M count=1000 -
Test write speed
time dd if=/dev/zero of=/dev/sdx bs=1M count=1000
-
¶ OTG
-
On M2U console:
Execute
/usr/local/bin/adbd.shthen execute
ps -ax | grep adbdto see if adbd is set up
-
On PC terminal:
-
If adbd was succeed to set up, insert OTG-USB interface to M2U and PC(with Ubuntu system)
-
Execute
adb devicesto see if PC has recognised M2U OTG
-
If yes, we could execute
adb shellto connect M2U by adb now
-
