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,

[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
