Hello,
I want to add RS485 on UART4.
I found:
https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/BB-UART4-RS485-00A0.dts
But can´t compile the dts.
`
root@c0a80090:/home/user/bb.org-overlays/src/arm# dtc -O dtb -o BB-UART4-RS485-00A0.dtbo -b 0 -@ BB-UART4-RS485-00A0.dts
Error: BB-UART4-RS485-00A0.dts:45.1-9 syntax error
FATAL ERROR: Unable to parse input tree
`
Can someone help me please?
My electrical designer tell me, he need a pin to set transmission direction. Not sure if RTS/CTS are working.
But I read the BBB has a RS485 support?
My Linux Version:
`
Linux rsuarttest 3.8.13-bone63 #1 SMP Mon Aug 11 20:08:34 UTC 2014 armv7l GNU/Linux
`
Thank you!
