vic liu

Hi Sir:

I want to UART5 as RS485 to communicate with the other device

now UART5 can receive data but can't make it send data out

Can you give me some suggestion

Best regard

Hi Biser

I check the OMAP serial driver is same with this page http://e2e.ti.com/support/embedded/linux/f/354/t/266128.aspx

and i can see the RTS output high or low

When I set RTS output high , it failed to send data

but RTS output high , it can receive data

Could you give me more information about this

It confuses me for few days
