记录 用tiny6410 j-link eclipse 在线调试裸机代码leds

１．nand flash烧写uboot 并且启动nandflash uboot，用来初始化6410，进入uboot命令行界面

２．在terminal中输入JLinkGDBServer -device ARM11

3.设置eclipse中的debug配置

其中初始化的部分是这样的

# tiny6410_config
# connect to the J-Link gdb server
target remote localhost:2331
# Set JTAG speed to 30 kHz
monitor endian little
monitor speed 30
# Reset the target
monitor reset
monitor sleep 10
#
# CPU core initialization (to be done by user)
#
# Set the processor mode
monitor reg cpsr = 0xd3
#config MMU
#flush v3/v4 cache
monitor cp15 7, 7, 0, 0 = 0x0
#/* flush v4 TLB */
monitor cp15 8, 7, 0, 0 = 0x0
#disable MMU stuff and caches
monitor cp15 1, 0, 0, 0 =0x1002
#Peri port setup

如果不想在terminal中启动JLinkGDBServer,那么需要在eclipse中这样设置
