| Build instructions |
| ================== |
| |
| As a regular user configure and then build: |
| |
| $ make acmesystems_aria_g25_128mb_defconfig (128MB RAM variant) |
| or... |
| $ make acmesystems_aria_g25_256mb_defconfig (256MB RAM variant) |
| |
| $ make |
| |
| Writing to the MicroSD card |
| =========================== |
| |
| Assuming your Aria G25 baseboard has a MicroSD socket, for example with |
| the Terra baseboard, you'll need a blank MicroSD (obviously) initialized |
| in a particular way to be able to boot from it. |
| |
| Assuming the card is seen as /dev/sdb in your PC/laptop/other device |
| you'll need to run the following commands as root or via sudo. |
| |
| Make sure all of the card partitions are unmounted before starting. |
| |
| First we'll need to create two partitions: |
| |
| # sfdisk -uM /dev/sdb <<EOF |
| ,32,6 |
| ; |
| EOF |
| |
| Then we'll need to create the empty filesystems: |
| |
| # mkdosfs -n SD_BOOT /dev/sdb1 |
| # mkfs.ext4 -L SD_ROOT /dev/sdb2 |
| |
| We'll populate the first partition (boot) with the relevant files: |
| |
| # mount /dev/sdb1 /mnt |
| # cp output/images/at91bootstrap.bin /mnt/BOOT.BIN |
| # cp output/images/zImage /mnt |
| # cp output/images/at91-ariag25.dtb /mnt |
| # umount /mnt |
| |
| And the root filesystem afterwards: |
| |
| # mount /dev/sdb2 /mnt |
| # tar -C /mnt output/images/rootfs.tar |
| # umount /mnt |
| |
| You're done, insert the MicroSD card in the slot and enjoy. |
