由于笔记本没有并口,我买了个J-LINK V8回来一开始还以为能用H-JTAG烧写,但是并非想的那样,在网上找了一圈,觉得这个方法最简单。
实验板: TQ2440
1、将j-link链接至开发板,打开J-Flash ARM,选择target->connect,会出现以下提示
Connecting ...
- Connecting via USB to J-Link device 0
- J-Link firmware: V1.20 (J-Link ARM V8 compiled Dec 1 2009 11:42:48)
- JTAG speed: 5 kHz (Fixed)
- Initializing CPU core (Init sequence) ...
- Initialized successfully
- JTAG speed: 8000 kHz (Auto)
- J-Link found 1 JTAG device. Core ID: 0x0032409D (ARM9)
- Connected successfully
2、打开工程FILE->open project,这里对应的是TQ2440的norflash配置,其使用的为AM29LV160DB,在网上找到该型号的工程 AM29LV160DB.rar
其他开发板也可以自己找
3、打开要烧写的文件,我需要烧的为uboot FILE->open
4、开始烧写 target->program
可能会出现 do you want to earse the affected area before program?的提示,点击是后出现烧写进度条
提示
Programming target (219120 bytes, 1 range) ...
- RAM tested O.K.
- Erasing affected sectors ...
- Erasing sector 0, 1, 2, 3, 4, 5, 6
- Erase operation completed successfully
- Target programmed successfully - Completed after 73.407 sec
到这里烧写过程结束了,启动单板,进入了uboot
