Setting up a Physical Device
A list of currently tested devices is maintained in the Reference Platforms page.
Always reference the documentation of the board you have selected for assembly instructions and requirements. At a minimum you will need the board, a power source, and a microSD card.
If support for your wireless network devices are not available in the Fedora image, it will have to be added after installation. You will need a wired connection to complete the install of the layered package.
For the Fedora disk images:
The Raspberry Pi WiFi is supported in the base image.
wcn36xx-firmwarefor the Dragonboard will need to be added later.
The Fedora IoT image is currently 4GB in size. The best speed class depends on the usage. A faster speed class is better for writes but the trade off is slower read speed.
Documentation for your board may also recommend specific SD Card choices as well as required physical sizes for each device.
Raspberry Pi discusses card size and speed class in their SD Card Documentation.
The 96Boards specification is simply that all boards have a microSDHC socket present.
|The following procedures will overwrite everything on the micro SD card. Be sure to backup any data before continuing!|
If you have not already downloaded the image, do so now and make a note of the download location and filename.
There are several options for determining the media device name.
lsblkcommand before and after inserting the card. The new device that appears on the list is the device for the media. If your microSD card has partitions, locate the name from the line that is type 'disk'. In this example the device name is
mmcblk0and will be referenced later as
$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT mmcblk0 179:0 0 14.9G 0 disk ├─mmcblk0p1 179:1 0 142M 0 part /run/media/user/22DA-CAE8 ├─mmcblk0p2 179:2 0 1G 0 part /run/media/user/8b87a5af-12c7-4990-940e-5b457336b11f └─mmcblk0p3 179:3 0 2.9G 0 part /run/media/user/cce2e189-9aee-4b3e-b031-aac9bdc632c9 ...output omitted...
If you have the
udisks2package installed you may find the
udisksctlcommand helpful in determining the media device name. It will show the model and only the device name without the extra partition information. In this example, a 16GB SanDisk Ultra shows as 'SL16G':
$ udisksctl status MODEL REVISION SERIAL DEVICE ---------------------------------------------------- SAMSUNG MZSLW1T0HMLH-000L1 S308NAAH501124 nvme0n1 SL16G 0x51821336 mmcblk0
Finally, the kernel messages will show the addition of a device. In a terminal window before inserting the device run:
$ dmesg -w
$ sudo dnf install arm-image-installer
Display the usage for the utility. This will display an example command:
$ sudo arm-image-installer Usage: arm-image-installer <options> --image=IMAGE - xz compressed image file name --media=DEVICE - media device file (/dev/[sdX|mmcblkX]) Optional --addconsole - Add system console kernel parameter for the target --addkey - /path/to/ssh-public-key --args - Optional kernel parameters listed in quotes --norootpass - Remove the root password --relabel - SELinux relabel root filesystem on first boot --resizefs - Resize root filesystem to fill media device --sysrq - Enable System Request debugging of the kernel --target=TARGET - target board for uboot -y - Assumes yes, will not wait for confirmation Help --supported - List of supported hardware --version - Display version and exit Example: arm-image-installer --image=Fedora-Rawhide.xz --target=Bananapi --media=/dev/mmcblk0
For the Raspberry Pi Model 3 B/B+ use:
For the Dragonboard410c use:
Provide the correct path for the downloaded image and the microSD media.
XXX with the location of your media. It will be
mmcblkX depending on hardware:
$ sudo arm-image-installer --image=Fedora-IoT-[version].raw.xz --target=dragonboard410c --media=/dev/XXX
Other options of interest:
--addkey=option will place a specified ssh public key into the
--resizefsoptions will expand the
/sysrootpartition to use all remaining space on the microSD card.
If you wish to use a serial console you’ll need to configure it. Details for the Raspberry PI are here.
