Firmware upgrade for EM9293 fails on linux

hookprobe.com · February 23, 2025, 3:54pm

Hello,
Have you experienced the same problem when trying to update the firmware on RHEL 10?

I am trying to update the firmware.
Modem was not communicating with the UGW (after approx 1 hour)
Tried to update the firmware

Now after the firmware update failed, also the Modem cannot connect any longer to the network.

seems you did not specify the download port /dev/ttyUSB0
for example:

Sure but there’s no device in RHEL with tty
no qcserial no usb just cdc_mbim

is this common for RHEL or … is just a problem on my side.

dmesg | grep tty

Did you install the MBPL USB driver?

Hello … Yes, I did, but I think the driver isnt supported by RHEL 10 … redhat – will try debian to see what is going on …

does it work now for the fw-download tool?

hookprobe.com · February 25, 2025, 7:11pm

Hello. YES. Works on Ubuntu – on RHEL 10 doesnt work. The driver qcserial isnt suported on RHEL. So I advise everyone else not to use this Modem with RHEL. Thank you !
