Issues in UART1 of DM365

Other Parts Discussed in Thread: WL1835MOD

Hi All,

I am in need of some basic level instructions for getting UART1 up and running properly on DM365. I'v been struggling on this since some time now. And one more thing that i am very much confused with is RTS and CTS. I need to use flow control for my peripheral (WL1835MOD). For transmission of data RTS/CTS lines need to be high or low ??

There are two UART1 and i am using GPIO34 and GPIO25 for UART1. I have gone through this forum and found so much useful info about muxing for this alternative UART1. But still it doesn't work.

  • My RTS/CTS lines are low all the time, is that expected ?
  • The data I'm sending on TX bus or echoing on ttyS1 , is not correct when i probe TX line with scope.

A list of files which need to be modified for getting UART1 up would be very useful. As i have modified dm365.c , mux.h etc.

Any suggestions would be appreciated.

Thanks

Brajesh
