Raspberry Pad 5 + CM4
Is it possible to install RatOS on 8gb cm4 on a Pad5?
I bought this as the Pi have been on back order.

I installed on a 32GB CM4, 8GB I don’t believe it will work, it fails on a 8GB SDCard

I guess it seems like I messed up, do anyone know the minimum requirements, 2gb ram and 32g emmc?
I can't find any info about minimum requirements for the install on os.ratrig.com,

Not 100% but I think you don’t want the emmc CM4.
Why wouldn't you? (Except if it's too small)

My bad, I see it’s in a pad5. That shouldn’t be too bad to flash the CM4 as it’s easy to get to/move to a computer.
@maxx6360 have you tried and it failed? If not, I’d just try it.
1gb mem is plenty. You want at least 16gb emmc or no emmc (sd card, easier).

I’ve tried with a SD card 64gb, but it does find it during boot. But SD might only work on a no emmc version?
Indeed. It’s one or the other.

Thanks, looking for a new one. Seems I always learn the costly way. 😂 But I guess it’s how it sticks? 🤦♂️
Confirmed!
Yeah the CM4 uses the same pins for eMMC and SD. So you can't have both. You can however mod your CM4 with eMMC to use SD instead, but it requires some pretty steady hands 😄
My RPi 3A ony has 512MB and it runs fine but I would really go for 1GB RAM if possible
yes 512 is fine, but i don't think you can get a CM4 with 512mb ram
For the price of a CM4 I would not go that route and instead sell it (fast) hint hint @maxx6360 😉
And i'd still say 512 is juuuuuust enough, i'd like the additional headroom personally 😄
Indeed, 1GB is way more comfortable 🙂

I think I’ll just have to see what’s available and get that, BTT didnt have any in stock either.
@miklschmidt Maxx raised a point on minimum requirements for RatOS
If you look at https://os.ratrig.com/docs/installation there's this minor mention of "(16GB or larger)." but I' believe this could be improved with a specific Minimum Requirements section to be clear and specific?
Do you want me to wip something up?
Yes i agree
That would be great!

@miklschmidt So would it be possible to install RatOS natively on a CM4 with emmc without using an SD card?
In this case I’ll order one and a base board
Yes 🙂
It's just a little more complicated, you need to mount the eMMC storage as a usb device on a pc
Hence why i usually recommend no eMMC
I have this running fine

That's good news! And when it's mounted I will use Balena Etcher to write the RatOS Image, just to be sure?
Which Baseboard are you using, the BTT Adapter, the Waveshare or another one?
A Pad5
You have some jumpers on the Pad5 you have to set in order to be able to write to the EMMC.
You have to use the official Raspberry image writer.
This is all documented in the Pad5 manual, don't know on other baseboards
yep
You have some jumpers on the Pad5 you have to set in order to be able to write to the EMMC.That's the same for all of them
You have to use the official Raspberry image writer.No, you can use Balena Etcher (and you should).

Just remember to order it with a emmc of 16gb or larger. 😀

thank you both, ordered the 1GB 32GB emmc vairant now.
sorry for just coing back to an old post but do you know how to mount the emmc, ive followed all the instructions but cant get it to show up as a disk to flash with an OS
how did you mount the emmc as a disk mine shows up as a malfunctioned usb?
malfunctioned usb means it's working.. maybe 😅
Check if you can spot it in your favorite disk formatter. It shows up as "broken" on non-linux machines as it's an ext4 fs, windows no comprende.
I don't recall mine having that behavior
