Hummingboard II, first pacman -Syu in a year

[RobMeades]

Hi there. I'm using Arch on a Hummingboard II project which I'm just getting back to after ~1 year off. I've just taken a deep breath and done pacman -Syu. I have an SD card for boot which switches to SSD (on /dev/sda) for normal operation so, after a successful pacman -Syu, I copied (with -r) the contents of /dev/sda1/boot to the /boot directory on the SD card but that did not boot.

I noticed that the dtb files are now in a subdirectory of their own, dtbs, so I copied them all into /boot and that appears to have worked. It doesn't feel correct though!

Can anyone advise one what I should have done/should do?

FYI, uEnv.txt contains:

$this->bbcode_second_pass_code('', 'mmcargs=setenv bootargs root=/dev/sda1 rootwait rw console=tty1 console=ttymxc0,115200 consoleblank=0 video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB24,bpp=16 dmfc=3 ahci_imx.hotplug=1 pci=nomsi loop.max_part=15
')

Which uboot are you using? The one in our repos has been patched to take into account dtbs dir. You can also mount your SD card under boot so the kernel will go to the SD card automatically

Hi moonman.

I think I'm using this uboot:

You're right that I should mount my SD card under boot, never quite got around to it.

Install "uboot-cubox-i" with pacman. It scans for dtbs in both <root> and <root>/dtbs

Will do, thanks.

Coming back to tidy this up now, am I correct in thinking that in order to mount my SD card as the boot directory and avoid this misalignment happening again, I simply edit /etc/fstab to add the following line:

$this->bbcode_second_pass_code('', '#device mountpoint fstype options dump fsck
/dev/mmcblk0p1 /boot ext4 defaults 0 1')

FYI, a correct ftab entry would seem to be:

$this->bbcode_second_pass_code('', '
#<file system> <dir> <type> <options> <dump> <pass>
/dev/mmcblk0p1 /sd-card ext4 defaults 0 0
/sd-card/boot /boot none bind 0 0')
