Re: Fibocom L850-GL / Intel XMM7360
There are carrier firmware packages for some, but not all, carriers
(some use a generic carrier firmware instead). I'm not sure how you
are expected to flash them without the closed-source firmware download
tool, though.

Re: Fibocom L850-GL / Intel XMM7360
Hi Eric,
I think this is a very helpful hint!
We already started contacting Fibocom. If we know that there is in general a
firmware available which forces the module
in USB mode this would be a discussion option.
How does this firmware behaves in terms of provider specific firmware versions?
Are there carrier specific firmware
available too or is there a generic firmware necessary only?
Thank you & best regards,
Dennis

Re: Fibocom L850-GL / Intel XMM7360
On Chromebooks, we use the L850-GL in USB mode and it works well. I
believe the firmware we get from Fibocom forces the module into USB
mode, though, so that might not be super helpful for this discussion.

Re: Fibocom L850-GL / Intel XMM7360
Hi all,
thank you for these hints!
I think I will try the Intel XMM 7560 / Fibocom L860 modem as well.
@Dan: You said that there is a (alpha/beta) driver existing. Is there a
possibility to get it to have a try how this
behaves?
Thank you & best regards,
Dennis

Re: Fibocom L850-GL / Intel XMM7360
Hi Bjørn, your comment makes me digging deeper in why this modem can not working in both modes. I installed native Windows on the target device and tried to make this modem running in native Windows. There I saw that after using the modem the first time Windows issued a firmware update of that modem. After that firmware version 18500.5001.00.03.25.24 was installed. Now switching back to Xubuntu 20.04 I tried the usb approach once again. Now the usb switch worked in general. The modem was available at the USB bus but it was not possible to get a connection because of the issues described in https://github.com/xmm7360/xmm7360-usb-modeswitch and https://github.com/xmm7360/xmm7360-usb-modeswitch/issues/23 After that I booted native Windows once again and installed an older firmware version. I did this by forcing installing an older driver and modified the FWUpdater config file a bit. https://download.lenovo.com/pccbbs/mobiles/nz3wj22w.exe After that I had firmware version 18500.5001.00.01.20.86 running. Using this firmware version it was it was possible to get a connection in Xubuntu 20.04 using the usb switch. So, it looks like that directly after this devices leaves the factory there is just a bootloader firmware installed and no "productive" firmware. Using the PCIe mode it was still not possible to get it running with https://github.com/xmm7360/xmm7360-pci. The kernel driver can attach to the device successfully now but the python script failed.

That effort is currently stalled. And the pci-based driver you mention
supports 7560 and later, not earlier devices. Not sure how hard it
would be to adapt to earlier devices though.
It does exist, but it's not quite ready for upstreaming yet.

That sounds similar to the USB experience. Maybe the issue preventing it from booting up in USB mode isn't related to USB after all? Maybe there is a problem with the installed firmware? Did you confirm that this specific test device actually works? Or did you test multiple modems with the same behaviour?

Hi Dennis,
some time ago Johannes Berg was working on a WWAN subsystem for the Linux
kernel (
https://lore.kernel.org/netdev/20200225100053.16385-1-johan...@sipsolutions.net/T/#t
) which also mentioned the 'upcoming Intel 4G modem driver ("iosm")'.
Perhaps it might help to ask him what the current status of this project is.

Re: Fibocom L850-GL / Intel XMM7360
Hi all, I tested the PCI approach. Unfortunately I had no luck. The kernel PCI driver at https://github.com/xmm7360/xmm7360-pci can not initiale the modem correctly. The modem stays at status=0xfeedb007. This seems to mean that the modem is (still) booting. After 20 seconds probing fails. The kernel driver gives up waiting for the device to boot. So, both options: usb switch and native pci driver will not work. Are there any ideas how to continue?

Last year (Lenovo Thinkpad Whiskey Lake series) there was the possibility to choose between the slow modem (Fibocom L830-EB) and the faster option Fibocom L850-GL. This year the slow modem ist the fast modem of the last year and the fast modem is CAT16 Fibocom L860-GL.

Mostly based on the assumption that there will be one, and that the vendor-id will be something non-Intel in application mode. You can probably confirm this by capturing the full device descriptor, e.g by creating a udev rule to dump it or simply by snooping on the bus. If this assumption is correct, then the firmware was supposed to boot into an application mode and then reconnect to the USB bus with its real device ID and descriptors. This could be failing due to a firmware crash, maybe caused by this unexpected state. Or more likely: The firmware on this modem is built without support for the USB mode. Do you have any confirmation that it is actually possible to switch this firmware into USB mode? Are there other firmwares available with (possible) USB support? Anyway, FWIW, I'd explore the PCIe driver option first if I were you. That's the only mode tested by anyone, so it is more likely to work.

Johannes says the Intel folks will be submitting drivers to staging "any time now" for that family of devices (7360, 7460, 7560). What the actual architecture of those drivers is and how you communicate with them, I don't recall.

Correct link: https://github.com/xmm7360/reversing This is more in the vein of "things that might not be obvious from reading the code", as opposed to a clean freestanding documentation of the protocol, for now.

Almost makes me want to buy a device to play with ;-) Being responsible for a number of historical userspace API mistakes I should probably just shut up now But just in case you haven't been following this discussion: https://www.spinics.net/lists/linux-wireless/msg186483.html I have no idea where this has led.
