Hello, I have a simple TP-Link TL-MR3420, i installed openWRT v1 and I trying to connect it with USB LTE-GSM modem  Huawei E3372.
Unfortunately In default configuration TL-MR3420 didn't see E3372, so I found drivers for linux from forum https://unlock4modem.in/install-huawei- … fedora-os/  at huawei page.

Of corse it was a bug in compile time but I fix it by comment unexpected line with debug statement.

After instalation I was able to connect to internet on my ubuntu laptop, so I was thinking "If I can compile it on ubuntu I will be able to install on openWRT"

I simply login by SSH to TL-MR3420 and I download by SSH drivers it has something like 5MB and my TP-link has Flash: 4 MiB, so After download I got command "there is no space on device" so I cant unpack it or compile.

Is possible to omit this flash limitation? For example by mount external drive? (I tried with pendrive but openWRT didn't mount it correctly.

Or is any way to cross-compile and install only binary file on TL-MR3420?

I am new with openWRT so any idea will be helpfull how to solve this
