Can we please get an update or note on the “Booting Turris Omnia from mSATA SSD” docs page under “Preparation of SSD”, step 5 where it says “partition table GPT is recommended”.
The eMMC on my kickstarter-era Omnia has finally died, so I have converted over to boot directly from the mSATA drive. I was broadly following the guide steps which was working fine, but I could not get the Omnia to boot directly from the mSATA at all.
It kept stalling at “Waiting for root device PARTUUID=<uuid>” - which was using the uuid of the mSATA, but it never progressed. On a hunch, I reverted the partition type with fdisk in a rescue shell to regular type 83 (Linux) and wrote that back out to the disk and it immediately booted.
This page is labelled as for the Omnia 2019+, but I wasn’t sure if that was referring to the the older uboot versions (I have 2022.10) or a hardware variation between the older and newer Omnia’s, but it would help to be documented.
Actually, it looks like some confusion / conflict between Omnia versions might exist over the correct type to use here.
Referring to Issue #198 / Merge #332 where it was changed from “DOS” to “GPT” as the correct one to use. The DOS partition type would be limited to 2TB, so it makes sense to allow for larger ones.
The issue doesn’t appear to clarify what hardware version “GPT” applied to, so perhaps some internal Turris knowledge is needed to verify.
Hi, I mentioned it in the first post - 2022.10, but the full version string is:
U-Boot SPL 2022.10-rc4-OpenWrt-r16653+119-44ce70f0e2 (Sep 15 2022 - 18:21:35 +0000).
I’m fully up to date with all automatic upgrades, and as far as I know, nothing preventing any updates, so I assume this is the current one.
Ahh, I didnt know there was a hardware versions page. Yes, I have the CZ11NIC13 with 2GB RAM as I was one of the backers on Indiegogo. I still have the t-shirt
is it recommendable to get the newest firmware through OpenWrt Firmware Selector and is the only way install uboot on an SSD with a serial connection? I am not clear, if the eMMC uboot is only deactivated or deleted (might come handy as a fallback)
The process I followed per the docs page was simply to insert the SSD as the first entry in the boot order. The eMMC is (now) second in my case, so if I removed the SSD, theoretically it would/could boot from that if the SSD was removed or failed to boot.
(My eMMC has failed, so this isn’t an option for me anyway).
Also, just technically, you don’t install uboot on the SSD. You configure uboot to point at the SSD to boot from instead of the eMMC. uboot is the software that your device runs first at power on to do very basic hardware device initialisation & detection - just enough to be able to identify that a storage device exists and read a (linux) kernel boot file from it in order to initalise the actual (turris, openwrt, etc) operating system.
The uboot configuration is written to a tiny little flash chip (kind of like a PC’s BIOS configuration) that’s separate from any actual storage you’re reading the linux kernel from.
Hi @Vienna .you are mixing up stuff. The link you provided is for Vanilla OpenWRT not TurrisOS as a fork. You should avoid that. Unless you want to switch to OpenWRT
