1. 格式化nandflash
PATH路径优先用前面的
Arm-linux-gdb
# .bashrc
# User specific aliases and functions
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
export PATH=$PATH:/opt/arm-linux-gdb/bin
export PATH=$PATH:/usr/local/arm/4.3.2/bin
2. 安装JLink驱动
[root@cfm880 ARM-tools]# tar xvzf JLink_Linux_V434a.tgz
[root@cfm880 ARM-tools]# cd JLink_Linux_V434a
[root@cfm880 JLink_Linux_V434a]# cp -d libjlinkarm.so.* /usr/lib/ -f
[root@cfm880 JLink_Linux_V434a]# cp 45-jlink.rules /etc/udev/rules.d/
[root@cfm880 JLink_Linux_V434a]# ./JLinkGDBServer
