Hi,

I am trying to compile an openwrt with RM500Q-EA and kernel (6.6.x) but I am getting this error

Is there a new driver available for it?

Is the openwrt based on IPQ?
If it is not Qualcomm IPQ you don’t need the rmnet_nss.c

Hi @Bean.Wang-Q it’s using IPQ807x and I’m using NSS for the build

4

The essiest solution is to remove the rmnet_nss related setting in the qmi_wwan_q.

Otherway is that actually on IPQ807x, there is rmnet_nss.c in your sdk.

RMNET is already enabled on the QSDK, am I still missing something?
