where are instructions for building the sd card with the pre-built binaries software-dl.ti.com/.../wl18xx-pre-built-sdk8-r8.6.tar.bz2. I have followed the sd script process but non of the kernel modules load after bootup so I can not test Wi-Fi and BLE demos. I would like to test the BLE demos and I am not able to. Please help. I was told that the Release 8.6 has built in support for the Bluetooth.
