Trying to find driver for EC-25AF for a Raspberry PI cm4. Tried the drivers here: Quectel EC25 LTE but I get this error:

Any guidance?

The current kernel version is 5.15.68 but you choose the 5.3.

3

@Bean.Wang-Q Where can I get the latest drivers? The latest one I see in the download is 5.3.1.

4

I think you can try the commands like:

modprobe option;
echo 2C7C 0125 | tee /sys/bus/usb-serial/drivers/option1/new_id

@Bean.Wang-Q

So the latest drivers available to build from source are 5.4.1 correct? That doesn’t sound right.

Please email me the latest drivers for the EC-25AF. I’ve seen others on this form get emailed the latest copy of drivers. I will most likely need this because I am on arch Linux.

@Bean.Wang-Q
I did that:

[root@pikvm ~]# echo "2C7C 0125" | tee /sys/bus/usb-serial/drivers/option1/new_id
2C7C 0125

Still the same error because the latest drivers you have are 5.3.1:

Please send me the latest EC-25 linux drivers for kernel 5.15.68.

@Bean.Wang-Q Can you please send me the drivers for EC-25-AF for linux 5.15.68? Thanks.

8

Please check the message.

Your modem is supported by the standard drivers, you do not need to build anything.

@Bean.Wang-Q can i get the quectel-cm tool? I can’t connect on serial
