It was only detected by the stock firmware and I was not able to get PCIe working with linux-next or OpenWrt’s Linux 6.1 built from source. I have lots to do and already spent more than 2 days trying to figure out why, and I can tell you already that the PHY driver correctly sets the mode-swtiching bit to PCIe. So, as I wrote before, the cause for the M.2 slot connected via pcie2 @ 0x11280000 not working is most likely a difference in the clock setup or something broken in the clock drivers itself.

Thanks to Sam Shih of MediaTek this issue is now resolved and PCIe2 @ 11280000 works fine now. As expected the problem was with the clk setup, and it was not trivial to find:

That’s awesome, thanks. So is that fix merged to openwrt? If I build a new image will that fix be in there or do I need to install it?
Yes.
You can use auc, luci-app-attendedsysupgrade, grab the snapshot image or build your own from source – in every case the fix is now there and all 4 PCIe ports work. I still see some warnings regarding IO ranges which I didn’t yet have time to look into, but things seems to work just fine never the less.
Daniel and Sam, thank you for all your hard work on this, this is very exciting news!
I have a question though. I’ve got the same exact modem as you, but it doesn’t seem like there’s been any change to the kernel output on my system when using the latest snapshot release. Still many of the same errors, though the -517 error seem to have disappeared. I have confirmed the modem works when running off the bananapi release. Pertinent logs:

And the card is not appearing in lspci. I’m on snapshot (r25541-af860c4dbf) and it looks like my kernel was built today:
bpi-r4# uname -a
Linux bpi-r4 6.1.81 #0 SMP Thu Mar 14 13:24:16 2024 aarch64 GNU/Linux
Any ideas what might be missing? Like I said, same exact modem as yours!
Mhm,maybe p3 clock is teared down if in this slot is no card? Daniel have you tried this? Michael is this the case for you? I have pcie-modem here to test myself…
Please try updated snapshot or OpenWrt source tree, I’ve added more fixes and verified with T99W175 modem working fine now on my R4 also with OpenWrt’s Linux 6.1 (before I tried only with Linux 6.6 which worked for some weird reason…).
Today’s snapshot (r25557-8fb23465ca, kernel Linux bpi-r4 6.1.81 #0 SMP Fri Mar 15 14:25:03 2024 aarch64 GNU/Linux) shows no change compared to yesterday 
@frank-w I’ve currently got the modem in the B-key slot, M-key empty, and there is a wifi card in one of the mPCIe slots (a b-key wifi card with a B → mPCIe adapter, working fine with ath11k).
I have tried the modem in an mPCIe slot and it wasn’t brought up there either.
Can you try inserting nvme inzo key-m slot?
Ok, so your problem is then not related to PCIe2 @ 11280000 but seems to be a generic problem with that specific modem (my T99W175 modem is working fine in Key-B slot with snapshot downloaded from downloads.openwrt.org). Please open a new thread (as your problem is not related to this thread), explain which exact modem you are trying to use and post the complete kernel boot log of both, BPI firmware and OpenWrt snapshot. Thank you!
In typical tech support fashion, I was working on writing up everything for the ticket, and lo and behold my T99W175 is now working just fine on r25557:
# lspci

It turns out the problem was that when I flashed the new openwrt built, the system rebooted, but it wasn’t a hard reboot. After pressing the physical reset button, now the card comes up fine on boot!

but it is not detected in uboot ;( the pcie2/key-b slot needs a specific xs-phy which does not have a driver in uboot, but as we only need nvme in uboot which is connected via pcie3/key-m slot i guess we just drop this slot from uboot

I know this thread is a couple months old but it’s about the exact modem I’m trying to get working on the bpi r4 and I’m having the same problem as @dangowrt last posted about.
I’m currently running snapshot r26488.
I can see the modem listed in lspci

But no device is loading in /dev/
mmcli -m 0 says “couldn’t find modem”
dmesg is showing multiple lines of probe of xxx.pcie failed with error -110
I’ve installed a lot of both qmi and mbim packages to try and get this working. Not sure what I’m missing.
The image I am using did come from firmware-selector.openwrt.org, maybe that is the problem? It’s not one of these other images built by someone else? But reading through the thread it seemed to indicated the changes were merged into openwrt master?
However, the reference pull request doesn’t seem to exist anymore so I’m wondering if it actulally is.
Is there some file i’m supposed to manual modify to get it working or something?
The 110 error (etimedout) is normal for slots not having a card inserted (r4 has 4 pcie ports).
As you see card in lspcie this step is already done…so from pcie view card is recognized…
But i see the class seems not correct. This is maybe the problem why driver does not map. This is still pcie driver but later than normal “detection”
Ok, are you able to point me in a direction on what the next steps are to figure out / fix the problem? How do I get the correct class in lspci? Sorry, driver level stuff and beyond is a little out of my depth.
We had a similar issue with coral cards on r64,maybe it helps here
But i’m also no pcie expert
Hmmm bummer, I guess I’ll have to post somewhere else and see if anyone got this particular modem to work somehow. I don’t really have the time right now to try a figure out how to set up an environment and compile openwrt myself to try making any code changes.
To me it looks like you are simply lacking the drivers. Try installing
kmod-mhi-pci-generic, kmod-mhi-wwan-ctrl, kmod-mhi-net, kmod-mhi-wwan-mbim. That should allow you to detect and use the modem.
I had most of those already installed but a couple did install.
Now the modem is showing as a Wireless Controller in lspci

Kernel driver in use: mhi-pci-generic
Using driver mhi-pci-generic.
Still not being detected by ModemManager, and still no devices under /dev/ for it.
Probably is a driver issue, but not sure what driver I’m missing =/ Seems like I’ve installed nearly every package that has mhi, qmi, or mbim in the name lol
