Original question:
hello,
we have developed an AM3358 Based Custom Board with Ref. design of ti Sitara kit.
we have added WL1835 wifi chip at mmc3 interface
i am able to run wifi at WLAN0 interface
and bt configured at uart5
Started Guide
i have done changes in bt-en.sh according to my hardware and change mode of this file
#!/bin/bash
function bten_335_evm {
echo 66 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio66/direction
echo 1 > /sys/class/gpio/gpio66/value
echo "Done enabling BT"
local gpio="nshutdown_gpio=66"
local tty="tty=/dev/ttyS5"
local flow="flow_cntrl=1"
local baud_rate="baud_rate=115200"
sudo rm -r /home/root/tibt
mkdir /home/root/tibt
echo $gpio > /home/root/tibt/config
echo $tty >> /home/root/tibt/config
echo $flow >> /home/root/tibt/config
echo $baud_rate >> /home/root/tibt/config
}
while running bt-en.sh script getting this message....

i have verified in dso while tunning bt-en.sh then after BE_EN pin goes high to 3.33V
and RTS and CTS Status remains high
but after running ===> SetDevicePower 1
RTS pin status goes to low...
my UART5 configuration in dts file

};while i am running
echo aa > /dev/ttyS5 at that time i am getting aa data in uart5 before running be-en.sh script
what should i do...?
