Forum Post: RE: WL12xx WiFi+BT on AM335x - BT Initialization fails

[quote user="Sundeep Mandava"]

Hi,

First you need to have a UIM executable. For this you need to create a Makefile to compile UIM in “uim-sysfs” folder.

Once you have the uim-sysfs executable.

1. You need to create a script uim-sysfs.sh. This script should launch uim-sysfs.
2.  Insert this script into /etc/init.d/
3. Make a link in /etc/rc2.d/ with “ln –s ../init.d/uim-sysfs.sh S99uim-sysfs”.

Thanks & Regards,

Sundeep.

Hi Sundeep,

I downloaded and compiled uim-sysfs from gitorious and deployed to ti linux rootfs. Following error occurred when tried to run BT_Init.sh

root@am335x-evm:/usr/share/wl1271-demos/bluetooth/scripts# ./BT_Init.sh
