AGL

Mon Sep 11, 2017 3:57 am

Hi all i'm trying to load and image of automotive grade linux to a RPi 2 B+. I would like to know if a boot partition is necessary to boot? My image installation contains a boot directory, but it's not booting. I've seen that raspian and others have a separate boot partition, does it apply to all distros? Can anyone point me in the right direction?

Regards.

/boot MUST be formatted a FAT16, or FAT32
rootfs, since it's linux needs to be ext4, reiser, f2fs or other Linux native.

You need AGL compiled specifically for the Raspberry Pi 2B / 3B, there has never been a 2B+ model:

Thanks, this was helpful! However every time I write to disk, using

Code: Select all

sudo dd
, it writes a boot partition(fat32) and a rootfs, however the rootfs writes in ext3 not ext4, could this be a potential problem?

Linux native still includes ext2 & ext3. There's some compatibility between ext2, ext3 and ext4 (the ext4 driver runs a non-journalled ext3 fs in degraded mode).
