[U-Boot] Trying to redirect console in Gumstix Overo

[U-Boot] Trying to redirect console in Gumstix Overo

[John Wilson]

I would like to change the console from UART3 to UART2 on a Gumstix Overo platform.  Here is what I have done thus far, which doesn't work (as explained below): 

Made the following tweaks in include/configs/omap3_overo.h: 

    a. Changed the console definitions to be:

            #define CONFIG_CONS_INDEX                                     2

            #define CONFIG_SYS_NS16550_COM2                      OMAP34XX_UART2

            #define CONFIG_SERIAL2                                                2

    b. Changed the console line in CONFIG_EXTRA_ENV_SETTINGS to be: 

            "console=ttyS1,115200n8\0" 

This isn't quite working.  When I initially boot the Overo, I get the following brief output (on ttyS2, not ttyS1), but then the computer doesn't boot further: 

Texas Instruments X-Loader 1.4.3 (Feb 16 2010 - 10:36:47)

Reading boot sector

Loading u-boot.bin from mmc       


What else do I need to change?   Is there some default environment or NAND settings or anything else I need to change or get rid of before this will work?  I am running of an SD card. 

Any insight is very appreciated! 

John

Any insight on how to redirect the console output is very much appreciated.  Any
pointers from anyone who has changed the console output?

Best regards,

John
