Serial port on omap4460

Mohamed,

The TI OMAP releases (such as http://www.omappedia.com/wiki/4AI.1.7P1_OMAP4_Icecream_Sandwich_Release_Notes for ICS) already have the serial port enabled for sending and receiving data.  However, the port used on Blaze for the serial console is UART3.  If you are planning to use a different UART port for serial console on your board, you will need to change that in the following places:

- x-loader - In the header file (x-loader/include/configs), change these lines:

#define CFG_NS16550_COM3 OMAP44XX_UART3
#define CFG_CONS_INDEX 3

- u-boot - In the header file (u-boot/include/configs), change these lines:

#define CFG_NS16550_COM3 OMAP44XX_UART3
#define CFG_CONS_INDEX 3

- kernel - In /arch/arm/plat-omap/include/plat/uncompress.h, change this line:

DEBUG_LL_OMAP4(3,omap_4430sdp);

(This is just needed for early printk output.)

- bootargs - We use "console=ttyO2" for UART3.  This would be "console=ttyO0" for UART1, for example.
