Then this is not related to driver problem, right?
Yes, even I think so… But wasn’t sure.
On many sites, they mentioned regarding, hardware failure or so.
If not driver, can it be because of the firmware ?
You can try other firmware and see if there is improvememt
I tried to update using the fwdwl tool, but as it can’t detect the modem, it’s not able to update the firmware.
Any other ways of upgrading the firmware.
Or if you know, any other forums, where I can get help regarding this issue
As said before, you can upgrade firmware in windows
Also for those machines without hardware issue, you can install the MBPL usb driver and MBPL fw download tool
Yes, I tried with one machine (uprading the firmware and MBPL usb drivers), and this fixed the issue. Well, I have few more machines, I will do the same on others, and see if SIM registration issue gets fixed.
How to upgrade firmware in windows when, it has ubuntu already installed
You can install virtual machine in ubuntu
Or you can have dual boot for windows and linux
Okay, I get it. But With virtual box, as the host is not detecting it, the virtual box, won’t be able to detect. But still, lets see, I will try.
You can switch the usb to virtual machine
E.g.
But if it is not detected, maybe it cannot be switched
It detects the hardware now.
But, AT port is not being shown, and while updating the firmware using this command, getting below error, and update stops
sudo ./SampleApps/lite-fw-download/bin/fwdwl-litehostx86_64 -d /dev/ttyUSB0 -p /dev/cdc-wdm0 -m 3 -f ./Images -l log.txt
Modem not coming up in BOOT and HOLD mode in 60 seconds. Please check parameters. Application terminates.
what port is enumerated in dmesg?
I’m not clear on how to check. I typed the dmesg command. What to check specific in that ?
what do you see in dmesg after connecting the module?
BTW, you can also compare to a working environment
Actually the modem is already connected, to it. So, we don’t plug it.
And the difference I see is the usb drivers aren’t loading, as secure boot is enabled. Ubuntu is not allowing to load unsigned drivers, when secure boot is enabled.
Tried to sign this drivers by generating a key as mentioned on many pages on internet. But it doesn’t work.
The problem with this machine is its an headless machine. So, can’t access the BIOS directly. So, it’s hard to disable the secure boot.
Then have you installed virtual machine?
I am not sure how would I access the virtual machine console, as it doesn’t have any display port associated with it.
you better ask your support team on how to install driver
<warn> Modem couldn't be initialized: Couldn't check unlock status: SIM not inserted
What could be the reason for this issue. Any idea ?
Do you check the followings?
Ati
At!uims?
At+cpin?
