Yup thats the port you need to connect to.
Buy a cheap USB->UART adapter (e.g one with the CP2104 chipset) and some "gpio" wires e.g for a raspberry pi and try the following.

Install a serial client like tio on linux or putty on windows and open the serial connection to the adapter (115200 BAUD)

Warning: do under no circumstance connect the 3.3V from the adapter to this header!
Next, try to locate, TX, RX and GND on this connector by simply swapping around the wires until you get a working connection in your terminal.
Hint: If you can read stuff but not type,your RX is hooked up correctly but you need to find TX.
Hint2: If you get garbled output your RX could be correct but the GND connection is wrong.

Most adapters are labeled, so it should be pretty straightforward to play around with this.

If the BMC is the culprit, it is possible to flash a new BMC firmware using this serial port but it will be painfully slow, but if you have 24 hours + to spare it should be fine. (There is a faster way but that requires way more setup and instruction work and a working u-boot bootloader).
(I can provide details later if you are willing to take this route)

Thanks for all these details. I bought the first adapter a few days ago and received it yesterday. I will have the 2nd later.

I messed around with the FIDI adapter, using only 3 wires (rx tx gnd), but was only able to receive some garbled text even after I tried all 24 combinations. I did:
1. connect all power cords and with PSU on
2. try different pin positions
3. while all this time have the adapter connected to the 2nd computer
4. make sure COM4 is always shown under windows device manager and PUTTY connected
5. I also measured the voltage. The first 3 pins (from left) is ~3.3V higher to the 4th pin.
Did I do something wrong? Should I start all over (power, usb connection etc.) every time switching the pins?

you should know: the issue can also be a worn out BMC FW chip(too many flash writes)
had that issue with old FW on h11 epyc board. with a new flash chip the board runs fine again.
especialy the HW reset action result in a dead end makes me thinking this way.

Could be. Is this the chip?
I do not plan to replace it due to lack of skills... just curious. This says 256MB though but I couldn't find anything saying 32MB (OYY). There is also an identical one 2 inches to the right saying BIOS.

256mbit = 32MByte

 

[adam2eden]

256mbit = 32MByte

LOL right... I read it wrong

Is the baud rate correct?

 

[adam2eden]

Is the baud rate correct?

Yes the baud rate is 115200. I just tried the FIDI cable on my EPYCD8 board and got a login screen... I guess this means the BMC chip is bad?

You could attach an UART Adapter to the BMC Debug port and see if it boots up, but only use this as last resort if the seller can't help. I don't think the board is dead, it's most likely the BMC that is corrupted.

The usual troubleshooting steps
- test with board outside a case (to make sure there's no short circuits)
- check memory & CPU installed correctly
- check CPU socket (no bent pins)
- is your router handing out DHCP correctly?
- connect a power switch to front panel PWR and check if fans spin on power

means the BMC is dead now or takes time to init.flash.

Thanks guys for all your help. Finally I contacted Tyan and they said they would try to fix the board for a small charge since the warranty expired this May.

Has anyone used a SK Hynix P41 in the M.2 slot on this motherboard? It’s a Gen4 PCIe SSD and I think the earliest hardware revision of the motherboard is Gen3 only for M.2 slots. I don’t see a way to set the M.2 slot as Gen3/Gen4 - just the PCIe slots

Some update:
While researching for the UART I found out ch341a and test clip so I thought I'd give it another try before sending it back. I flashed the BMC with the one (v3.0) from Tyan's website using NeoProgrammer. After a few tries the BMC is fixed. Now I got a heart beat and IPMI !! So happy with this experiment.

However, I already have everything installed with H12ssl. Now I have to decide if I want to save some money with Tyan...

Hello team STH.
Hoping my fellow enthusiasts can assist me where Tyan support seems slow.
I have an epyc milan setup in an asrock. I wanted to get this Tyan 8030 and found one for sale that was a return. Since I can return it to the retail seller I figured at worst I would be out the time and hassle.
Anyway the issue I am dealing with is the BMC password has been changed by the previous owner.
root / superuser does not work. Since the password has been changed, I cannot update it via the bios either.
Tyan support has been slow and vague.

So thats my question to my fellow STH'ers. What is the process to reset the BMC to so I can then access and use the IPMI remote (LAN)?
Looks like Tyan support clocked out for the day before they were willing to give me the process.

I have access to the bios and BMC via the bios/console but thats in a closet and I want it like my asrockrack, on the lan.

Currently the bios is v2.02 & BMC is v3.00
I will move onto wanting to know how to determine if I have the 32mb vs 64mb chip so I know which BMC I can safely run but thats next.
Their page references a spreadsheet which I cannot seem to locate.

Thank you kindly

One way is to locate the BMC SPI flash chip as in the photo a few posts above, and look up the part number to see its size. It's a 16SOP footprint (8 pins on each side), next to the 4-pin BMC debug header. There's another SPI flash for the BIOS.

with local access to the host you should be able to add a new user with admin rights and change the password.
ipmitool

ipmitool

I appreciate the response!

I saw I could add another user/admin locally but how does that help resetting the root account password?

I created a new admin but was not sure if it should be a 1 or 8. Saved and rebooted, tried removed access under the newly created user and it failed.
This is my 1st epyc and 2nd board so I am still learning the server side of life.
Thanks

have you enabled the user ?
cmds similar like this.
Enable this user on ID 3
# ipmitool user enable 3

Set privilege for this new user on ID 3
# ipmitool channel setaccess 0 3 [callin=on|off] [ipmi=on|off] [link=on|off] [privilege=level]

Only in the bios.
Newb to ipmi other than the asrock and it was no issue as 1st owner to set root was me.

Do i need to download an ipmitool?
Currently I have proxmox hypervisor and Linus vm running on the servethank you again for the guidance.

in the BIOS
user access = enabled
channel 1 (dedicated BMC/LAN) connect over this port not other LAN.
user privilege linit = admin...

its there for linux as well. get it the usual way.
you have to be on the machine, not remote or VM.
there are millions of guided for ipmitool. you better ask there no here,

Thank you kindly sir. You have been most helfpul. I will follow your lead and report back.
At work now.

So I'm seeing errors with a new Proxmox install. I'm getting the same error as the link to serverfault.com below.

I have the ASUS Hyper M.2 x16 Gen 4 Card NVMe expansion card. Setting the slot to AUTO or PCIe GEN4 generate the issue in the screenshots below. Setting to GEN3 as mentioned in the link stop these errors all together. Is there a fix for this? Should I just ignore the error and keep it at GEN4?

Also if the slots are numbered bottom to top in the BIOS, why do you think the error says "slot 0"?

AER error on ROMED8-2T board with m.2 NVMe disks - plausible? How to fix it?

Recently I added two PCIe 4.0 NVMe m.2 disks to a system (AMD Epyc 7402P on a ROMED8-2T board). Since then I receive warnings telling me that there were correctable AER errors on the physical layer.

I have the same mobo and running into the same issue as you are. Did you ever find a fix? PERHAPS a setting in the bios?

 

[oneplane]

Does the redfish implementation on the BMC expose the fan settings? I had a quick look through the manual but I didn't spot it (except the GET versions but reading them isn't the only goal )

Hi I also purchased tugm4470, ended up with 7302 non p. Of coarse all was well shipped and Is running great on my test situation. I do have a question though.....I update the BMC firmware to the latest through IPMI. Can I trust to due the same for the BIOS? Is the file to use for the BIOS the .rom file rom the BIOS download if done through the IPMI? BTW I have the 64mb board. Oh I have never heard the beep but then again its in my basement Im getting old and my wife says deaf as well...LOL

Thank You.
