器件型号：TMS320F28388D
主题中讨论的其他器件：UNIFLASH

我们目前正在尝试在生产中实现串行闪存编程器功能。但是、我们很难将固件的生产版本上传到处理器。

当我们在输出十六进制文件中包含设置 DCSM 密码的功能时。我们会得到校验和错误或空白错误(如果处理器已预编程)。这是我们要包含的文件(除了密码文件本身)、我们似乎找不到导致问题的任何特定内容。如果我们编译到.out 文件并使用 UniFlash 将其发送到处理器、则一切正常。

/* 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.
