How can i verify my new motherboard is working?

Hello. I just made my first computer and recently had a usb error on journalctl and that was because of me not seating the USB cable correctly. I wonder how i verify if my motherboard is working because i've got some dmesg warnings and also a suspicious line in dmesg.

journalctl -p 3 -xb (This is my current journalctl so it's clean)
-- Logs begin at Tue 2020-07-07 20:43:29 CEST, end at Thu 2020-07-09 12:23:52 C>
-- No entries --

dmesg --level=err,warn (I've verified this is only warning level but i've a hard time to understand what the PCI thing actually means for me)
[    0.153666] Expanded resource Reserved due to conflict with PCI Bus 0000:00

[   23.628646] kauditd_printk_skb: 17 callbacks suppressed

dmesg | grep -i "ccp" (This also scares me because i don't find much about it and it says the bios might be broken which i guess means the motherboard)
[    2.619401] ccp 0000:0a:00.1: enabling device (0000 -> 0002)
[    2.619524] ccp 0000:0a:00.1: ccp: unable to access the device: you might be running a broken BIOS.


Can i actually troubleshoot and verify in some way what these lines mean and if my motherboard is correctly configured and has no hardware faults?

Re: How can i verify my new motherboard is working?

ccp is 'crypto co-processor' which is specific to Ryzen processor. I can't help much since I don't use Ryzen and others in the forum might be happy to help.
Have you installed your microcode?

Re: How can i verify my new motherboard is working?

Yes it is up to date and im using ryzen 3 3300X

warning: amd-ucode-20200519.8ba6fa6-1 is up to date -- reinstalling
resolving dependencies...
looking for conflicting packages...

Packages (1) amd-ucode-20200519.8ba6fa6-1

Total Download Size:   0.02 MiB
Total Installed Size:  0.04 MiB

Edit: It seems like when i went through that with Y i didn't get "Total download size: 0.02MB" anymore when doing the pacman -S command again. I'm gonna restart and see if anything changed.

Edit 2: That was just the package cache, nothing changed and i got the same warnings and messages.

You might as well check you have the latest BIOS.

Re: How can i verify my new motherboard is working?

I've never done any BIOS update as far as im aware. Thats a thing i wonder how i could do? It says instant flash which seems to be that you can use a USB for updating it even on Linux but where is the latest updates and how do i do it exactly?

Motherboard: B450M-HDV R4.0

Edit: I think i'll be able to update the BIOS now because of a thread that showed where the official bios updates are so i'll come back and say if it worked against the warnings.

Be careful with BIOS update. Make sure you're sure on what to do (it's motherboard specific) and would be good if there's a backup and a way of flashing back the old BIOS just in case.

I have updated to the latest 3.80 version (From the 3.70 version) which is not marked as unsafe for my Matisse cpu (It was unsafe for some other gen cpu). I still got all the warnings and messages i mentioned before.

I also found a trusted computing option in the bios which says "No security device found". It says that it can be enabled/disabled for the bios so that might be the thing related  to CCP.

Yes possibly that Bios switch could be the key. ccp is about cryptographic API so has to do with security. I found this link in Gentoo that has a mention of it.
It looks like there's nothing wrong with your MB. You can boot, update BIOS, etc. Usually mother board problems involve kernel panic, freezes and random reboots. As I said, I don't use Ryzen so can't be much more help.
Just see and disable the BIOS security switch and monitor what happens.

Re: How can i verify my new motherboard is working?

Now i dont get any display from the computer. Could disabling trusted computing have done it? I also tried and enabled xmp with 3200mhz 1.20 changing it to 1.35v 3200mhz (my ram is corsair vengeance 3200mhz and uses 1.35v from factory specs).

Re: How can i verify my new motherboard is working?

I don't think it has to do with your RAM but with the amdgpu. I am slowly seeing a pattern here:

amdgpu 0000:08:00.0: amdgpu: Trusted Memory Zone (TMZ) feature not supported

so it looks like amdgpu might just be be affected by the disabling of trusted computing. Again, I wish I have the answer. You can try to enable it back and see if you get your display back, but I don't think it's your RAM.

Re: How can i verify my new motherboard is working?

I shorted the cmos jumper to reset it and could boot, i changed xmp again and it worked. I won't disable the trusted computing thing anymore and it seems i will have to live with the CCP message, but my motherboard is probably fine then.

I think your AMD SEV doesn't work (i.e., you may not have /dev/sev at all). I've just spotted your bbs thread while trying to make AMD SEV work on my system, which didn't go well. Details are here: https://bugs.archlinux.org/task/69350

The original poster has not been back since last July, so I am going to consider this thread abandoned and close it.
