Hi everyone,
We are using a Variscite SOM iMx6q that has a wl1271 wireless module on it. We are able to perform ifup/ifdown only once on the wireless module. Any attempts to do this again causes the wireless module to fail with the error:
wlcore: ERROR timeout waiting for the hardware to complete initialization
We turned on debug options for the driver to see what was going on when it works correctly (the first time) and when it fails. Below is the output.
Working correctly:
