附上当前设置的CMD文件

你好，能否介绍一下你的加密方法是哪里看到的吗？我查找了很多资料都没看到类似enableCSM .set 1的做法。

你好，是例程里自带的CSMPasswords.asm文件

;// TITLE: DSP2802x Code Security Module Passwords.
;//
;// DESCRIPTION:
;//
;// This file is used to specify password values to
;// program into the CSM password locations in Flash
;// at 0x3F7FF8 - 0x3F7FFF.
;//
;// In addition, the reserved locations 0x3F7F80 - 0X3f7ff5 are
;// all programmed to 0x0000

; The "csmpasswords" section contains the actual CSM passwords that will be
; linked and programmed into to the CSM password locations (PWL) in flash.
; These passwords must be known in order to unlock the CSM module.
; All 0xFFFF's (erased) is the default value for the password locations (PWL).

; It is recommended that all passwords be left as 0xFFFF during code
; development. Passwords of 0xFFFF do not activate code security and dummy
; reads of the CSM PWL registers is all that is required to unlock the CSM.
; When code development is complete, modify the passwords to activate the
; code security module.

enableCSM .set 0 ;0-disable CSM, 1-enable CSM

.sect "csmpasswds"

.if enableCSM == 1 ; enableCSM=1
.int 0xFFFF ;PWL0 (LSW of 128-bit password)
.int 0xFFFF ;PWL1
.int 0xFFFF ;PWL2
.int 0xFFFF ;PWL3
.int 0xFFF4 ;PWL4
.int 0xFFF5 ;PWL5
.int 0xFFF6 ;PWL6
.int 0xFFF7 ;PWL7 (MSW of 128-bit password)
.else ; enableCSM=0
.int 0xFFFF ;PWL0 (LSW of 128-bit password)

; For code security operation, all addresses between 0x3F7F80 and
; 0X3f7ff5 cannot be used as program code or data. These locations
; must be programmed to 0x0000 when the code security password locations
; (PWL) are programmed. If security is not a concern, then these addresses
; can be used for code or data.

; The section "csm_rsvd" can be used to program these locations to 0x0000.

lab05b本身应该是不带有CSM代码的，上述代码可能是之前版本的CSM代码。你试一下以下位置的f2802x_csmpasswords.asm：
C:\ti\c2000\C2000Ware_3_02_00_00\device_support\f2802x\common\source
另外，上传代码的话最好用回复框右下角的“使用高级编辑器编辑文本”，里面有上传代码的摁键，点击之后用代码上传工具上传。

你测试过吗？如果用最新的文件还是有问题，那就是其他地方的错误了。

我使用F28069F时候也遇到同样的问题，请问您解决了吗？

没有解决
