UART CTS/RTS Support BSP 6.09/6.10

Hi. I hope im in the right forum.

Im running the WinCe "S1SDKOMAP_DVSDK_OMAPWINCE_EA_06_10_00"

Copyed from /BSP/readme.txt

<5/2/08        6.00.00>
- Initial Release

***********************************
Known Hardware Issues
***********************************

- The EVM DB9 UART1/2 and UART3 serial ports only support RXD and TXD,
there are no modem handshake signals available.

 

Is this still the case? running 6.09 now and read thru the 6.10 changes.

I need to check the Clear to send flag. Is this possible in 6.09/6.10?

Im using Uart1.

  • Of the forums here, this is the right forum, though for the most part for support on the Windows CE BSP you would have to work with the third party BSquare, though it is possible one of the other WinCE users in the community can comment. I have not installed the WinCE BSPs myself as they are currently supported by BSquare, though I would suspect there are release notes or a newer readme.txt in the newer release that would answer your question.

    Hello Jonas,

     The problem is in the hardware and not the BSP. The PC board hardware has no physical connections to any pins of the DB-9's (UART 1/2, UART3) other than RXD and TXD. TI would need to re-design and build a new board with all signals connected to the DB-9 connectors in order for the additional handshake lines (RTS,CTS,DSR,DTR) to function.

    Just to inform others with the same question.

     

     

  • Thank you for following up on this, that certainly makes more sense as to what they were saying in the readme file, so this is something you would have to have implemented on a custom board as the OMAP3 itself does support RTS/CTS. It is good to know that the functionality is supported outside of the EVM by the BSP.
