x470D4U - Stuck in VLAN ID Setting

The latest BMC is pretty old (2021-09-10), so you'd think a recently purchased board would come with it, but then, maybe it's an old stock.

When I bought mine, over 2 years ago, I needed to update both BMC and BIOS, as I'm using R3-3300X.

Definitely update BMC first, and then BIOS, without ever trying to start the system. I used a Chromium based browser (Brave). I vaguely recall Firefox not working correctly. Make sure to disable any sort of script blockers, etc.

I'd hope BMC update has a fail safe, but if something went wrong there, it could be ugly. Maybe there's a way to boot into a normal OS using an older chip, like 2000-series Ryzen, and re-flash the BMC from there.

Did you try the dedicated IPMI port (Realtek controller)? Did you have a DHCP server on that net, so it can get an IP address? I'm not sure what IP address it would start with if you don't have a DHCP server on that LAN.

No other ideas.

On an unrelated note, I'm using the latest publicly released BETA BIOS (AGESA 1.2.0.7), and the auto-detect for PCIe mux didn't work, so I had to go into BIOS and force it to split it to x8/x8, so it can see both cards. Weird.

Remember, for BMC stuff, you don't need to boot the computer. You just power it and give it a couple of minutes for the BMC to start. It runs off 5VSB (Standby).

I just noticed you bought a R5-5500. I think that is a bad choice for this board. First it's not listed in the supported list (which may or may not matter), but more importantly, ECC memory won't work. I mean, it might not work at all, or it might "work" but not in ECC mode.

My understanding is that for Raven Ridge, Picasso, Renoir, and Cezanne CPUs, only PRO versions support ECC memory. R5-5500 is actually R5-5600G with the iGPU disabled, so it's Cezanne based.

I know PRO versions of the APUs (4650G, 4750G, 5650G, 5750G, etc.) are kind of hard to purchase from a reputable vendor. I actually own a PRO 2200GE and PRO 4560G, but for X470D4U build, I went with an R3-3300X, as I didn't need the iGPU.

The rule is, non-APUs all support ECC, but only PRO APUs support ECC.
As I said, that's why I picked R3-3300X for my X470D4U.
I would recommend something like R5-5600 if you can get it for cheap.
It's Vemeer chip with full 32MB L3 and no iGPU.

The problem with PRO APUs (or CPUs) is that, they're not sold in retail markets.
I had to buy a Lenovo machine to extract the R3 PRO 2200GE (but I was able to make the Lenovo work by putting in a retail Athlon 200GE). I bought the R5 PRO 4650G from Hong Kong. Newer Lenovo will vendor-lock the CPUs, so they won't work in anything but Lenovo motherboards. I swore off Lenovo since then.

I can't be sure if it will fix your issues, though.
For one, I believe you should be able to access IPMI and update BCM firmware and BIOS firmware even without a CPU!!! The main power is never even applied to the board! Only the BCM is powered.

So even if the CPU you installed isn't supported, you should still be able to access BCM through IPMI and mess with that part, assuming your power supply is giving it 5VSB power.
