Hi ,
I am getting the "wlcore: ERROR ELP wakeup timeout" ,when i try to scan wifi after executing the calibrator commands .
Before executing the calibrator command ,I can successfully scan and connect to Access point .
Below is my test steps: (Execute calibrator PLT mode on , then make interface up in normal mode, it shows error , then make PLT mode off and try to up and scan wifi interface in normal mode)
1 : # ifconfig wlan0 up
Powering wl18xx: on

After that am continuously getting this ELP timeout error and all the wifi commands failed.
I am using WL1837 module and our kernel version is 3.10.9. I am using this module in our custom board with freescale Cortex-A9 processor.
Please help me regarding this issue. I am not able to find the root cause.
Regards,
Jisha
