[参考译文] TMS320F28377S：DCSM 错误。

您好：

您能否提供有关 闪存编程流程的更多详细信息？  您 一次编程多少位？ dcsm.asm asm/dsm.cmd 存储器 段 不与 128 位对齐的地址对齐、因此可能会在编程期间导致问题。  

此致、  

马特

首先上传闪存内核（由 TI 提供）
成功握手后、我开始上传 hex 文件、  256 字节块  最大
我的正常代码正在上传成功。 但 scnerio 后出错。

1. 使用  dcsm_security_tool 十六进制文件。 当我不启用 ZONE1 标头时、LFU 会成功更新、但当我启用 ZONE1 标头（在全新 MCU 上）时、LFU 会失败。 我已经把这两部电影都打动了

2.其中我需要设置 128 位对齐地址。

e2e.ti.com/.../hex.files.rar

以下是会产生错误的 dcsm.cmd 文件

/* this linker command file is to be included if user wants to use the DCSM feature on the device
 * DCSM  means Dual Zone Code Security Module.
 * This linker command file works as an addendum ot the already existing Flash/RAM linker command file
 * that the project has.
 * The sections in the *_ZoneSelectBlock.asm source file is linked as per the commands given in the file
 * NOTE - please note fill=0xFFFF, this helps if users include this file in the project by mistake and
 * doesn't provide the needed proper *_ZoneSelectBlock.asm sources .
 * Please refer to the Blinky DCSM example in the controlsuite examples for proper usage of this.
 *
 * Once users are confident that they want to program the passwords in OTP, the DSECT section type can be removed.

我 在代码中启用了 DCSM 模块（通过 LFU 成功刷写）、这次失败、我永久启用了 pswdlock 并禁用了 CRClock。  
0x78010 转 FFF0。 OTA 失败、令人惊讶的是重新命名代码仅能正常工作 DCSM 部分 LFU 失败

您好：

抱歉、我是因公出差、没时间为 E2E 提供帮助。 我明天会看这个主题。
