Hi Vijay,
If IRQ line is not handled properly wl1271 does not comes up properly, and wlan interface will not be up. In my case the interface is already up, working some interrupt is causing the processor to restart the wl1271. What is this interrupt ?. Wl1271 has only one IRQ line and how it OMAP L138 differntiate between normal interrupt and this "error" interrupt?
