3、点击小虫子图标进入debug模式,进入之后如果显示没有连接JTAG的话先点击Connect Target连接JTAG,然后点击Tools - On Chip Flash,在On Chip Flash中的Code Security Password - Key0~7中输入正确的密码,然后点击Unlock。这样就解锁了,系统会提示:
C28xx: GEL Output:
ADC Calibration not complete, check if device is unlocked and recalibrate.C28xx: Flash Programmer: Warning: The configured device (TMS320F28335), does not match the detected device (). Flash Programming operations could be affected. Please consider modifying your target configuration file.
C28xx: Starting device unlocking...
C28xx: Device unlocked. To clear the programmed password, please erase Sector A of Flash memory.
解锁成功后你就可以正常使用芯片进行烧写flash了。
4、如果你希望彻底解锁芯片(以后启动都不需要输入密码解锁),那么按照上述系统提示的“To clear the programmed password, please erase Sector A of Flash memory.”操作。接着刚才的步骤,跳到On Chip Flash中的Erase Sector Selection,选择Sector A(默认是全选的),然后点击“Erase Flash”。这样就去掉密码了,系统会提示:
C28xx: Erasing Flash memory...
C28xx: GEL Output:
