The development using an ARM device is exciting, but sometimes it’s more time expensive. The ARM toolkit utilities is a collection of scripts published on my GitHub repository.
When you want to try a new Linux kernel version, you must download the new kernel and compile it (or download a ready to use version from the manufacturer) and upload it into the SD card, changing, if required, the bootloader and some other thinks.
To simplify the switch from a kernel version to another, I’ve prepared a shell script that simplify this process.
1. Modify your micro SD card
Connect to your Aria G25 board using ssh as usual and verify you current Linux kernel version:
root@ariag25:~# uname -r 2.6.39+
Well: you have the 2.6.39 version. Mount your first partition of the micro SD card:
root@ariag25:~# mount /dev/mmcblk0p1 /mnt root@ariag25:~# cd /mnt root@ariag25:/mnt# mkdir 2.6.39 root@ariag25:/mnt# mkdir 3.11.6
In other words your first partition of the micro SD card must have a directory for every kernel version you want, named as the version, without other chars.
2. Copy kernel related files
Every ARM board needs to boot some files: a bootloader, a kernel image, etc.. Now copy current files (remember that your board now have linux kernel 2.6.39):
root@ariag25:/mnt# cp * 2.6.39/
3. Download new Linux kernel
Now you can download the new 3.11.6 version from the Acme Systems website:
root@ariag25:/mnt# cd 3.11.6/ root@ariag25:/mnt/3.11.6# wget http://www.acmesystems.it/download/microsd/A3/image.bin root@ariag25:/mnt/3.11.6# wget http://www.acmesystems.it/download/microsd/A3/boot256.bin root@ariag25:/mnt/3.11.6# mv boot256.bin boot.bin root@ariag25:/mnt/3.11.6# wget http://www.acmesystems.it/download/microsd/A3/at91-ariag25.dtb
NOTE: you MUST download the boot128.bin file if your board is equipped with 128MB RAM.
Now unmount the previous mounted partition:
root@ariag25:/mnt/3.11.6# cd ~ root@ariag25:~# umount /mnt
4. Download switch script
About to finish:
root@ariag25:~# wget https://raw.github.com/mgesmundo/arm-dev-toolkit/master/kswitch.sh root@ariag25:~# chmod +x kswitch.sh
Done: now you change your active kernel simply typing:
and selecting your kernel (see the image below):
