来源:互联网 发布:天谕凌体型捏脸数据 编辑:程序博客网 时间:2024/06/06 09:53
the problem root cause is for the uart , in /arm/samsung-dev-uboot/include/configs/ smdkx210single.h we have
"#define CONFIG_SERIAL3 1
so we need set uart port to 2 in uboot args and kernel
smdk210>setenv bootargs 'root=/dev/ram rootfstype=ext2 init=/linuxrc console=ttySAC2,115200 mem=512M'
setenv bootargs ‘noinitrd mem=512M console=ttySAC2,115200 root=/dev/nfs nfsroot=172.16.96.215:/arm-nfs ip=172.16.96.250:172.16.96.215:172.16.96.215:255.255.254.0::eth0:off’
and in kernel
>make menuconfig ->system type
由 (0) S3C UART to use for low-level messages
变为 (2) S3C UART to use for low-level messages
and make menuconfig ->kernel hacking
由 (0) S3C UART to use for low-level debug
变为 (2) S3C UART to use for low-level debug
