如何使用uniflash烧写nandflash，并实现nand启动

、利用NOR Flash

种利用JLink能够烧写程序NOR Flash完首先利用J-FLASH ARMu-boot.bin烧写进NOR Flash（记烧写NOR Flash0x0起始址处）设置发板NOR Flash启候系统进入U-boot命令行模式候打J-Link commander输入命令：r 看JLink否能识别发板信息（判断JLink否连接）

J-Link commander命令先假设u-boot.bin电脑D盘根目录

1. speed 12000 //设置TCK12M载程序快

2. loadbin d:\u-boot.bin 0x30000000

注意：0x30000000想要载u-boot.bin发板内存址内存址根据同发板设定同本文使用FL2440片系统S3C2440内存挂载址区域0x30000000~0x33ffffff我需要u-boot.bin载片区域即

我U-boot命令行模式输入NAND Flash擦除写入命令即：

nand erase 0 40000

// 擦除0址始0x40000Nnad Flash扇区0x40000待写入U-boot.bin致度度必须NAND Flash页整数倍通需要比u-boot.bin实际度

nand write 30000000 0 40000 // 前面载0x30000000u-boot.bin烧写Nand

我再设置发板NAND Flash启即转载仅供参考

首先用CCS或是IAR调试烧写都是针对片内的RAM，芯片掉电或是重启以后，程序就没了。

你需要下载uniflash -simplelink来实现对片外sflash的烧写。
