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!
