How to change UART port from U-BOOT on NETRA EVM

Hitesh Viradiya

Hello,

I am using TI816X EVM with U-boot version "u-boot-2010.06-psp04.00.00.12" of "ezsdk_5_02".

By default, this Uboot uses UART2 as console port. On our h/w, we have used UART0 as console port.

I want to change the UART port, can anyone suggest how i can change it ??

I tried changing "DEFAULT_UART_BASE" flag in "arch/arm/include/asm/arch-ti81xx/cpu.h" file UART0_BASE as value (which was UART2_BASE originally).

Kind Regards,

Hitesh

In this file

include/configs/ti8168_evm.h

find this line (line 167):

#define CONFIG_SYS_NS16550_COM1 0x48024000 /* Base EVM has UART2 */

and replace with:

#define CONFIG_SYS_NS16550_COM1 0x48020000 /* Base EVM has UART0 */

That should help. Please, let me know.
