F2833x_EEPROM_Example实例的问题

Other Parts Discussed in Thread: TMS320F28335

    用这个程序跑了一遍,然后用XDS510再也连接不上F28335了,故障显示芯片locked,很奇怪,请问如何处理????

  • 可以将RST脚拉低再连仿真器,再进行解密,或者将BOOT方式跳选到0011(87~84)后连接仿真器再进行解密

  • “解密” 这个是如何操作的?

  • 将启动设置为0011(87-86),可以连接上,但是出现以下错误:

    1、可以确认ccxml文件芯片选择没错,它怎么就检测芯片不匹配呢?

  • 关于这个问题,我也遇到过,也没有解决,怀疑是芯片问题。

    至于解密,是指在烧写的时候进行了加密操作,再连接仿真器之后需要在On-chip Flash里输入密码,才能对芯片内部的程序进行擦除,修改
