# Juno Development Platform Support in meta-arm-bsp
|
|
|
|
## Howto Build and Run
|
|
|
|
### Configuration:
|
|
In the local.conf file, MACHINE should be set as follow:
|
|
MACHINE ?= "juno"
|
|
|
|
Juno is using a USB hard drive for root filesystem by default. The distribution
|
|
used must have ```usbhost``` and ```usbgadget``` in DISTRO_FEATURES (this is
|
|
the case in poky distribution).
|
|
|
|
### Build:
|
|
```bash$ bitbake core-image-minimal```
|
|
|
|
### Update Juno SD card:
|
|
|
|
The SD card content is generated during the build here:
|
|
tmp/deploy/images/juno/firmware-image-juno.tar.gz
|
|
|
|
Its content must be written on the Juno firmware SD card.
|
|
To do this:
|
|
- insert the sdcard of the Juno in an SD card reader and mount it:
|
|
```bash$ sudo mount /dev/sdx1 /mnt```
|
|
(replace sdx by the device of the SD card)
|
|
|
|
- erase its content and put the new one:
|
|
```bash$ sudo rm -rf /mnt/*```
|
|
```bash$ sudo tar --no-same-owner -xzf tmp/deploy/images/juno/firmware-image-juno.tar.gz -C /mnt/```
|
|
```bash$ sudo umount /mnt```
|
|
|
|
- reinsert the SD card in the Juno board
|
|
|
|
### Create an USB hard drive:
|
|
|
|
Linux root file system should be stored on the second partition of an USB
|
|
drive that must be plugged on the Juno Platform.
|
|
|
|
This partition should be initialized with the content of the filesystem
|
|
generated by yocto that you can find here:
|
|
tmp/deploy/images/juno/core-image-minimal-juno.tar.bz2
|
|
|
|
To do this
|
|
- Format a USB disk, create two primary partitions (ext4).
|
|
- mount the secondary partition
|
|
- untar tmp/deploy/images/juno/core-image-minimal-juno.tar.bz2 on to the
|
|
secondary partition.
|
|
|
|
### Run:
|
|
You must insert the SD card and the USB drive and power-on the Juno board.
|
|
The console should be available on the second serial line:
|
|
screen -L /dev/tty.usbserial 115200
|
|
|
|
On the first boot the images will be flashed which can take some time.
