Hello,

Which module are you using? EM/MX74xx or the EM75xx series? Are you running ARM 32 or 65-bit arch?
What Linux kernel on your host?

@jleitner

  1. Sierra Wireless EM7565
  2. ARM-32 and mips have been reported to load GobiNet.ko error
  3. arm-32 linux kernel version is： 4.1.0
  4. mips kernel version is 3.10.49

Regards

Is this occurring on both MIPS and ARM archs? Both of those kernels are supported and so please try the latest .54 drivers on the source site: https://source.sierrawireless.com/resources/airprime/software/usb-drivers-linux-qmi-software-s2,-d-,35n2,-d-,54/

We might need to provide you a patch if you still can’t properly load the GobiNet driver.

Where are you located?

@jleitner

I tried the latest .54 driver, ARM reported the same error, the kernel always prints the error message. The kernel of mips is also reported incorrectly. I am from Guangzhou, China.

You will likely need a patch for the GobiNet driver. Are you working through a distributor or direct Sierra Wireless account manager? We will need a support ticket created by the Chinese distributor or account manager in order for our Linux team to provide you with the patch. Please let me know and I will forward to the appropriate team.

Hello, any update on this issue? I have a GobiNet patch that might address this issue.

Hi， @jleitner

Sorry, I haven’t submitted this question to the distributor. When I submit the problem to the dealer, I will inform you, thank you.
Recently, I adapted the EM7565 device on the mipsel platform. The driver is loaded without error, but there will be some zombie processes.

No worries and good to hear about the initial testing with the EM7565 for MIPSEL. For further support on issues that might require gobi driver patches and the like, again best to have your distributor submit a ticket with sierra wireless.
