Fibocom L850-GL / Intel XMM7360
Hi all, we get our first Lenovo 2020 series Thinkpad models and would like to make WWAN/LTE working. The devices of this year support 2 different WWAN/LTE modems: a) CAT9 Fibocom L850-GL / Intel XMM7360 b) CAT16 Fibocom L860-GL That applies at least to all T- and X- series Thinkpads. So there is no option to have a pure USB based LTE modem inside. We focused on the Fibocom L850-GL / Intel XMM7360 because this modem has the option to switch into usb mode. Whats the most practical way to support the Fibocom L850-GL / Intel XMM7360 modem? As far as I know there are two main directions: 1) Switch the modem into usb mode I used this https://github.com/xmm7360/xmm7360-usb-modeswitch to switch the modem to usb mode. Unfortunately this seems not to work completely. After disabling the PCIe link I can notice the device at the usb bus but after round about 7 seconds it will disappear from the usb bus. So, the script said: Found XMM7360 modem at :2c:00.0 (\_SB_.PCI0.RP07.PXSX) Parent port is at :00:1c.6 Disabling PCIe link... OK! After that dmesg shows this: [ 930.843781] usb 1-7: new high-speed USB device number 16 using xhci_hcd [ 930.996572] usb 1-7: New USB device found, idVendor=8087, idProduct=07f5, bcdDevice= 0.00 [ 930.996577] usb 1-7: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 937.683939] usb 1-7: USB disconnect, device number 16 So, in general I think there should be USB lines routed to the M.2 slot but I have no idea why the device leaves the bus. It is possible to run the script again and again but in the end it will always disconnect automatically. That means it is not possible to issue the AT commands to switch to MBIM mode. Does anybody has a hint how to make further investigations on this? 2) Use the PCIe based driver I read this https://github.com/xmm7360/xmm7360-pci but I currently didn't try it. I would like to know how is the current situation from ModemManager perspective. Will the ModemManager work together with the pcie driver or is it in development/planned? So, in conclusion: Whats the best solution to support this modem? Would it be better to use the USB mode or should we use the PCIe mode instead? If somebody has ideas or hint to make this modem work, please tell me :) Thank you & best regards, Dennis ___ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel

Hi Bjørn, thank you for your estimation. > 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? > I don't have a confirmation that the USB mode will really work, especially on the new models. 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. Regarding the Lenovo Thinkpad Whiskey Lake series models I found some threads where the USB mode switch worked: https://forums.lenovo.com/t5/Other-Linux-Discussions/WWAN-Fibocom-L850-GL-and-Linux-support/m-p/4318903?page=1#4327397 https://gmt-24.net/archives/1461 Thats why I assumed that this might work at newer Thinkpads as well. Especially https://gmt-24.net/archives/1461 shows that your assumption regarding the bootloader and application mode seems to be correct. This comes out directly after disabling the PCIe link and directly after that: [ 162.799214] usb 1-6: new high-speed USB device number 5 using xhci_hcd [ 162.940604] usb 1-6: New USB device found, idVendor=8087, idProduct=07f5, bcdDevice= 0.00 [ 162.940612] usb 1-6: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 169.651754] usb 1-6: USB disconnect, device number 5 Now bcdDevice changed to real device id.

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.

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 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?

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

broadband-modem-mbim related questions
Hi all, now we are going to evaluate the new "Fibocom L860-GL-16 4G CAT16" WWAN modem based on "broadband-modem-mbim" plugin. Is there a recommendation which ModemManager, libmbim, libqmi version to use or should we just pick the most current main branch? I there a schedule of a stable version (1.20?) available which includes support of the "broadband-modem-mbim" plugin? Thank you & best regards, Dennis
Re: broadband-modem-mbim related questions
Hi again ;) sorry, in the first mail my expression was not clear enough. I am referring to the new "Intel" plugin (intel/mm-plugin-intel.c) based on intel/broadband-modem-mbim-intel.c. Looking at branch mm-1-18 this plugin seems to be not available now. This is available in main branch only. This implies that there is no tagged release available yet. Having this in mind, I would like to repeat my two questions: Is there a recommendation which ModemManager, libmbim, libqmi version to use or should we just pick the most current main branch? I there a schedule of a stable version (1.18.10, 1.20.0 ?) available which includes support of the "Intel" plugin?
