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:



jordan@jordan-X240:~/QMI/MBPL/MBPL_SDK_R21_ENG2-lite.bin/SampleApps/lite-fw-download$ sudo ./bin/fwdwl-litehostx86_64 -l pcie_mbim.log -f /home/jordan/Desktop/EM919x_FW/Release2/ -m 4 -d /dev/ttyUSB0 -p /dev/cdc-wdm0 -t 1 -w SWIX55C_02.08.01.00-002.cwe -n SWIX55C_02.08.01.00_GENERIC_020.007_002.nvu

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

[ 0.047718] printk: legacy console [tty0] enabled
[ 0.505339] 00:01: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A

Did you install the MBPL USB driver?
