Linux/WL1837MOD: Wlan interface is not showing

Hi,

Can you please supply the full kernel boot log?

"wlcore: ERROR couldn't get hw info" usually means something is wrong with the hardware connection to the wl18xx module.

BR,
Eyal

Hi Eyal,

These are the complete boot log.

Hi,

mmc0: new high speed SDIO card at address 0001

Seems like the module is detected on the sdio bus.
What version of the drivers are you using? Are you using our latest R8.7_SP3 release or are you trying to use in-tree drivers in your linux kernel?

Best Regards,
Eyal
