Hello,
Some background information -- We have an existing product based on iMX6 with WL1831. I am in process of upgrading the Wireless drivers from R8.5 to R8.6
During boot, line-discipline time's out installing. This causes a long delay in boot-time.
But, after boot finished, if I write "hciconfig hci0 up", it starts without any problem.
What might be the reason for this?
Regards,
Erez
