Motherboard Group Buy/Crowdfunded Modded BIOS for the Asrock A300m (Deskmini A300)

nerditation · Oct 2, 2020

I just came across this custom PC building video, where he put an A300 motherboard and a big GPU together with some custom made brackets and stands etc.

in the video he tried to put a Ryzen 3700X CPU onto an A300 motherboard but failed, and finally ended up to use a 2400G APU.

what I find interesting is that he showed in the video there is actually an option in the firmware menu to switch graphics mode. I wonder if it is actually possible to use switch to dedicated GPU and then switch to a CPU? anyone has a PCI-E adapter/riser could try it out maybe?

@Danlopez1222 very interesting so far.
Not ruling out the option of a custom logic glued to the EEPROM resulting in a product like ATECC608A, thanks to @steven0220 for that thought.
If we talk about PSP - there is a section in the UEFI which deals with it. If it's used in the boot process, makes somehow sense it terms of 'could be related'.

I don't know of your abilities, but would it be possible to compare the PSP section of the UEFI to see if it's trying to access I2C address of the knoll.

Are you able to see it's address on the I2C Bus, using analyzer? I guess so. It would be interested if this address is to be found in PSP UEFI code.

Somehow I did not get notifications on your thread, I'll also dig in

thanks for sharing.

Edit: UEFI Bios .hex holds a firmware blob for the PSP, which is custom IP, LattceMico32 - it would be it's code where the address should be found

Greetings

I don't know the offset of the PSP fw, but it's something that is changing (mostly) between AGESA stack versions and not regular BIOS updates. Although - I guess it could be the case, but like more major BIOS version number jumps.
So making a diff against to different AGESA versions could provide a guess.

I'll will finally respond to the maker of ryzen_nb_smb and share a link to Dan's findings/effort

Edit x: I've asked FlyGoat for permission to post his answer on the boot process here. I'll keep you updated

Yes, it does not work

Ok, me here again, with an update. FlyGoat allowed me to post his answer.

To the boot process:
I was asking upon the boot process, and how I know it was, and how it is...
My main point of this e-mail was the ability to write SMU Features. (Where e.g. the o/c flag lives)

[...]
Actually on Fam17h AMD systems, a small bootstrapc called ABL will be
execuated on
PSP, than it will initialize IMC, copy UEFI part of flash to RAM and tan
bring-up x86 cores.
[...]
Feature flag will be transmited to SMU in firmware's Dxe stage, AFAIK
it's in SMUv12Dxe driver.
However, you can't enable a feature here if the feature had been baned
by fuse or firmware.
[...]
SOC VID and RAM VID is stored at APCB, but wether to show this option in
BIOS is up to vendor's
decision.
For more about APCB please check Coreboot's documations.[1], [2].

[1]: https://doc.coreboot.org/soc/amd/family17h.html
[2]: https://doc.coreboot.org/soc/amd/psp_integration.html

After Dan's progress, we continued:
Main point was to go for the PSP and the Knoll activator, which FlyGoat seems to know a bit of.
I also spoke about the PSP-IP, which I thought would be the LatticeMico32 (showed 2014's slides from CCC event)...

[...]
All I know is Knoll is a I2C/SMBUS chip attached under I2C1 of Ryzen
chip, there is a stage in PSP early bringup
process called Knoll auth. The protocol is not clear to me.
[...]
PSP is a IP Block in Ryzen chip, it is not relavent to external
components, but I guess it's PSP who is communicating with Knoll.
PSP's firmware is stored together with BIOS.

Btw the CCC talk is a little bit outdated, it only applies to Fam15h chips.
For Fam17h chips there are newer researches, see:
https://github.com/PSPReverse
https://fahrplan.events.ccc.de/congress/2019/Fahrplan/events/10942.html
https://media.ccc.de/v/36c3-10942-uncover_understand_own_-_regaining_control_over_your_amd_cpu

It is actually a Arm Cortex-M IP.

If it's ARM Cortex-M A5, it's - I guess - somehow similar to STM32Fxxx series, for example. It provides I2C, etc..
but the ARM-Core should feature a SWD debug interface - don't know how that's exposed to the outside world..

From the GitHub hint, there is a PSPTool. Here on 3.60S:
Btw: psptrace maybe on knoll.txt extract?! I highly suggest checking out last link.

Hi all, finally bought 4650G, it's a beast! From a local dealer, tray version for 220€, sold my 3400G for 145€

Running on A300 with P3.60R, single core boost 4.3 GHz, all-core boost 4.25 GHz

AMD Ryzen 5 PRO 4650G @ 4241.4 MHz - CPU-Z VALIDATOR

Unfortunately, ACPI S3 seems not supported, so PC can't go to sleep, checked in W10 LTSC, W10 Ent 20H2, Debian 9. Also mentioned on reddit. Anyone here encountered the same - maybe some fix for that? Thanks!

S3 not supported due to PRO cpu in use, as its a security risk having a PC sleeping according to AMD.

That's rather weird, S3 is enabled and works perfectly on my ASRock B550 ITX board with my 4650G.

Nice to know. But as the Deskmini don't have a "real" chipset i guess it lacks the different inputs from the chipset to sleep. I'm waiting for a Noctua cooler for my X300 and 4750G.

What RAM are you running? Can you get 3200MHz on your X300?

I have ordered some Crucial CL16 3200MHz, waiting for them to arrive.

Renoir is officially not supported on A300, that can be a reason. I guess it's more about missing entries for ACPI within UEFI. But it doesn't work even on X300 where it should work. Read the link I've pasted...

Please add links or quotes where you got this non-sense from

BTW so sad @Danlopez1222 not hearing from you anymore. Are you fine? Is everything going well?

Asus has a similar system 'ASUS PN50-BBR748MD-CSM' with a Renoir/Zen2 based 4800U which is similar to 4650G-Series (lookup the silicon specs)
Asus does not have such a problem, using chipset-less design. (on BIOS-level)

Mini PC PN50｜Mini PCs｜ASUS Global

Ultra-compact computer with 4000 Series AMD Ryzen mobile processors, supports up to 4 displays in 4K resolution and up to 64GB DDR4 RAM, M.2 SSD, WiFi 6, Windows 10 and dual USB 3.2 Gen 2 Type-C

www.asus.com

And here you can see, that SoC-based ASUS System with Ryzen/Renoir DIE is supporting it well.

Hi, ASUS support thinks the problem is with the Windows installation. The support is not that wrong, because after a new installation, waking up from S3 / S4 works absolutely without any problems, but then Windows Update came (I suspect a driver update) and it shot again. I'll see which update is exactly the reason, but it may take a while. Greetings Helios

This leads me to the fact, that AsRock probably won't support it well (as in case of A300).
Think twice who you give your money to

I did it as well - won't repeat.

Here how it is being debugged (in some way):

Ryzen 4700U failing to enter suspend/modern-standby correctly (#1230) · Issues · drm / amd · GitLab

Brief summary of the problem: When I close the lid of my laptop, it does not actually enter the suspend/sleep state....

gitlab.freedesktop.org

Hey @awatry, I'm on an Envy x360 13, sporting a 3500U, similar issues, but it turns out these laptops do have deep S3 sleep support; but HP's ACPI tables don't announce it to the OS.

I ended up decompiling parts of the tables, editing, overwriting and recompiling.
...

I for e.g. have till this day the issue that the WoL-feature is not working on A300. It seems that there is a common route of cause. I dunno, me no AsRock.

Yeah, AFAIK AMD mobile platforms are all chipset-less, and a laptop without sleep would be ... rather terrible. So no, that's definitely not the reason. If I were to guess, ASRock simply hasn't tested it, and perhaps Renoir needs more 5VSB current than previous APUs or some such, meaning that it would need re-testing to ensure it works properly. That is obviously pure guesswork, but it's a possible explanation at least.

Hi all, anyone else having issue with SATA disks with 3.60R or 3.60S? I've got one 1 TB HDD for cold backups, thus is not used intensively. But when I tried to run my backup script, i get many Disk errors within the eventlog, system gets laggy and need long time to recover. With 3.60N no such issue... I've been trying one SATA SSD and it had similar issues, but haven't suspected A300 itself until I find this. Currently I have 2 NVMe disks populated + mentioned 1 TB HDD.
