APC8750 redirect console messages to serial port

[Diego Sueiro]

Folks,

I want to redirect the console messages from tty1 to ttyWMT0.

But when using setting bootargs to "mem=512M root=/dev/mmcblk0p2 rootwait rw console=ttyWMT0,115200" the system start-up crashes.

Here is the serial port output: http://pastebin.com/Q22edh7M

Folks,

I found the root cause.

If I stop u-boot before the APC logo been displayed the system will crash on start-up.

Here is the output from u-boot:

U-Boot 1.1.4 (Dec  5 2012 - 19:23:59)

WonderMedia Technologies, Inc.

U-Boot Version : 0.28.00.00

U-Boot code: 03F80000 -> 03FCEE38  BSS: -> 03FF0A88

boot from spi flash.

SF0: ManufID = C2, DeviceID = 2013 (Missing or Unknown FLASH)

     Use Default - Total size = 8MB, Sector size = 64KB

SF1: ManufID = FF, DeviceID = FFFF (Missing or Unknown FLASH)

     Use Default - Total size = 8MB, Sector size = 64KB

flash:

     Bank1: FF800000 -- FFFFFFFF

     Bank2: FF000000 -- FF7FFFFF

Flash: 16 MB

sfboot: NAND init:env nand config fail, use default flash id list info

T2=1, clk2=36, div2=18, Thold2=1, comp=1

Tim1=442368 , Tim2=589824

T2 is greater and not use

T=2, clk=18, divisor=9, Thold=0x601

divisor is set 0x9, NFC_timing=0x2424

USE_HW_ECC ECC12bit

Out:   serial

Err:   serial

Abort WMT Display Logo Function

WMT # 

But if I stop u-boot after getting APC logo displayed the system will boot.
