<div dir="ltr"><div dir="ltr"><div>This report is from quite some time ago but as I hit this issue when working with libqmi recently, maybe some of my debugging can help anybody else if they get this issue. In my case the upgrade is failing whenever I am using a slow baud rate. Each time I tried to upgrade an MC7455 with a connection using baud 9600 I would get this error. On a hunch I thought that this may be related to the issue. I redirected the upgrade output to a file and the upgrade worked fine, I sshed in and that worked fine also. </div><div> </div><div> </div><div>Another issue I noticed is that when upgrading is complete and the updater is waiting on a reply using the cdc-wdm port, if the higher enumerated of the two ports is used, the transactions will time out. For instance if the modem comes back up with cdc-wdm0 and cdc-wdm1 then if cdc-wdm1 is used this will happen 12 times and then the program will print an error also (seen below):</div><div> </div><div><div>[14 Jan 2019, 14:34:43] [Debug] [/dev/cdc-wdm1] sent generic request (translated)...</div><div><<<<<< QMUX:</div><div><<<<<< length = 11</div><div><<<<<< flags = 0x00</div><div><<<<<< service = "ctl"</div><div><<<<<< client = 0</div><div><<<<<< QMI:</div><div><<<<<< flags = "none"</div><div><<<<<< transaction = 1</div><div><<<<<< tlv_length = 0</div><div><<<<<< message = "Sync" (0x0027)</div><div> </div><div>[14 Jan 2019, 14:35:03] -Warning ** couldn't create DMS client after upgrade: couldn't open QMI device: Transaction timed out</div><div>[14 Jan 2019, 14:35:03] -Error ** qmi_device_release_client: assertion `QMI_IS_DEVICE (self)' failed</div></div><div> </div><div>No functional error, the modem upgrades successfully, it just errors and never returns to the linux prompt without user intervention.

Updating firmware in a mobile broadband modem (Pavlin Georgiev) ---------------------------------------------------------------------- Message: 1 Date: Mon, 9 Apr 2018 10:42:06 +0200 From: Pavlin Georgiev <<a href="mailto:pavlin@varna.net" target="_blank">pavlin@varna.net</a>> To: <a href="mailto:libqmi-devel@lists.freedesktop.org" target="_blank">libqmi-devel@lists.freedesktop.org</a> Subject: Updating firmware in a mobile broadband modem Message-ID: <<a href="mailto:f9757b9d-9cb8-d9d4-e6a2-021239289f59@varna.net" target="_blank">f9757b9d-9cb8-d9d4-e6a2-021239289f59@varna.net</a>> Content-Type: text/plain; charset="utf-8"; Format="flowed" My goal is to update the firmware of a broadband modem. I use qmi-firmware-update in combination with Sierra Wireless EM7455. That modem belongs to firmware series SWI9X30. I have read some of the update examples. I have made several experiments on EM7455. All of them have failed at the beginning of the update process. Now I try to try the cause. I ask you for cooperation. *HARDWARE* # lsusb Bus 003 Device 010: ID 413c:81b6 Dell Computer Corp. Note: a re-branded modem by Dell *DEVICE DRIVERS* I didn't use drivers from Sierra Wireless. Loaded modules are listed in the attached file. Note: I didn't seen module "qmi_wwan" in that list. Is the loading of driver "qmi_wwan" required? *SOFTWARE ENVIRONMENT* Distro: RHEL 7.5 x86_64 Workstation kernel-3.10.0-862.el7.x86_64 libqmi-1.20.0-1.fc28.x86_64 libqmi-utils-1.20.0-1.fc28.x86_64 Note: libqmi is from Fedora 28 repository. *UPDATE TRIALS* I have tried and update operation by specifying: A) THE VID:PID OF A DEVICE B) AN EXPLICIT QMI DEVICE Results are listed in the attached file. Thanks in advance for your advice. Pavlin Georgiev -------------- next part -------------- An HTML attachment was scrubbed...
