F28004x DCSM使用

Other Parts Discussed in Thread:UNIFLASH

使用c2000 ware中dcsm_security_tool例程,将RAM LSx、Bank0左右扇区分配到Zone1、Bank1所有扇区分配到Zone2,分别设置了2个zone的密码,debug烧录完代码报下面错误。

Susan Yang:

参考之前分享的文章:

e2echina.ti.com/…/dcsm

“以blinky_with_DCSM为例,如果把代码段写入FLASH A,并将FLASH A划入Zone1设置密码保护。在正确输入密码时,烧录操作可以正常进行。

而在不输入正确密码时,会出现解锁失败的提示,烧录也会报错。”

您是否有输入正确密码呢?

,

got2b:

使用UniFlash读出来的GRABSECT/RAM值,跟生成的.asm中的不一样

,

Susan Yang:

那您输入密码使用uniflash能否正常烧录?抱歉,对DCSM模块研究不多

,

got2b:

全新的dsp,错误发生在Flash programming 0x78020,是Bank0 Zone Select Block,密码在此区域。说明密码还没有写进去。

,

got2b:

这个文章已经看过,F28004x的DCSM稍有不同,生成的DCSM asm cmd文件已经和TRM手册比对过,没发现问题

,

Susan Yang:

是的,我看了一下,也没有发现有什么问题。建议您去英文论坛咨询一下BU:

e2e.ti.com/…/171

,

got2b:

F28004x注意事项:

1、一旦设置了Zone密码,Flash、RAM LSx的访问就通过GRABRAM/GRABSECT去抓取,所以务必将所有Flash和RAM LSx进行划分加密。

2、GRABRAM/GRABSECT的配置是Zone1和Zone2的组合配置,不是单独的,错误配置将导致无妨访问。

3、在(存在Boot pin不确定的状态)硬件上测试,DCSM一直未成功写入,硬件的缺陷会影响DCSM的写入。

4、第一次烧录加密代码不需要任何额外的设置,后续需要在CCS工程属性->Debug->Flash Settings,CSMPSWD密码区域填入相应的密码。

或者使用UniFlash烧录之前,先通过Settings & Utilities CSMPSWD密码区域填入相应的密码。

5、尽量不要设置Boot ROM相关的,只能设置一次。

谢谢您的分享!
