target配置.rar (65 K) 下载次数:7 target配置.rar (65 K) 下载次数:7 环境介绍：
使用的开发板是友善之臂的mini2440
仿真器是：H-JTAG
Mini2440 Memory 配置：
NAND flash：K9F1208(64M x 8 Bit)
NOR flash：SST39VF1601(1M x16 Bit) 地址范围：[0x00000000~0x001FFFFF]
SDRAM: HY57V561620 (2pcsX4Banks x 4M x 16Bit) 地址范围：[0x30000000~0x33FFFFFF]
该程序在runinRAM中是OK的，但是runinflash（nor flash）不成功，调试了N天都不行，求助各位大牛了哈~~崩溃了哈~~~
