As I said, the TX watchdog should *not* be initialized in PLT mode. Maybe you could add some prints in the driver to see when the watchdog timer is set up? Try to add a printk in every place where wl12xx_rearm_tx_watchdog_locked() is called to see where it is being armed. > If I use the "normal" firmware, i.e. ifconfig wlan0 up, it gets loaded > and I can search for the stations.
