求教关于 uboot ttl下打印信息 silent' mode

accmac

机器型号是bthh2b，isp定制的路由，目前adsl 可拨号，功能正常。。。
u-boot has 'silent' mode enabled  //原声uboot默认被开启，    不知道该怎么关闭这个模式，用netconsole 比较麻烦，步骤繁琐，我想直接用ttl ，不知道有没有高手出来指点指点，机器型号是bthh2b，ISP定制的路由，目前adsl 可拨号，功能都正常。。。就是想更完美点，


连接ttl 后SecureCRT信息如下：
U-Boot 1.3.1a (Jan  1 2012 - 10:38:10)

Board: DANUBE (0x30129083)
Chip V1.3
CPU Speed 333 MHz
DR Speed 166 MHz
FPI Speed 83 MHz

Setting up clock generators...
DRAM:  64 MB
Flash: 512 kB
In:    serial
Out:   serial
Err:   serial
danube Switch
NAND:  32 MiB
－－－－－－－－－
后面就停了，，，要等 tftpboot 上传image后，（uboot添加nc信息后 上传固件'加载正常 开机openwrt）
启动kernel后 TTL才有启动信息出来

查了一下，就知道一点点现在，望高手出来 提示提示Y(^_^)Y
