UART1 on omap4460

Mohamed,

I assume you have already looked at chapter 23.3 in the OMAP4 TRM for information about the UART port?  See the first link in the Resources sidebar on this page for the link to the public TRMs.

The pin muxing is done in the x-loader board file.  For example, for Blaze Tablet, this is the file x-loader/board/omap44XXtablet/omap44xxtablet.c.  If you need help configuring the pin muxing, you can also reference the Pad Configuration Tool, located at the same link as the OMAP4 TRMs.

Thank you Gina for your answer fast,

here is what i found in my omap44XXtablet.c of x-loader directory, however i havn't any idea for how to enable the UART1 and how can i get the tool wich allow me to build the MLO file.

    MV(CP(UART3_CTS_RCTX) , ( PTU | IEN | M0))  /* uart3_tx */ \
    MV(CP(UART3_RTS_SD) , ( M0))  /* uart3_rts_sd */ \
    MV(CP(UART3_RX_IRRX) , ( IEN | M0))  /* uart3_rx */ \
    MV(CP(UART3_TX_IRTX) , ( M0))  /* uart3_tx */ \

Best Regards,

For building the x-loader, you can follow the instructions here: http://www.omappedia.com/wiki/4AI.1.7_OMAP4_Icecream_Sandwich_Release_Notes#Building_X-LOADER_for_OMAP4470   (It is the same instructions, even if you are using OMAP4430 or OMAP4460, instead of OMAP4470.)

You have to check which pads you have connected your UART device to and then modify the corresponding pad configuration in omap44XXtablet.c appropriately.  Which pads is it connected to?

hi agin Gina, 

what do you mean by pad configuration ?

For information, i am using the serial port of my board  named UART1 RS232.

Best Regards,

Hi Venkat, 

i will take a look on this chapter.

Thank you for your answer

Best Regards,
