[参考译文] MSPM0G5187：J-Link 编程问题

抱歉、我来更正客户使用的是 MSPM0G3507

尊敬的 Eason：

您能否尝试使用 UNIFLASH 在 MCU 上执行批量擦除并重建映像、看看这样是否修复了错误？

此致、
Brian

Hi Brain、

经确认、在首次使用 XDS 在 3507 上执行批量擦除、然后使用 J-Link 对器件进行编程后、不再发生错误。

但是、当我使用 J-Link 编程器时、我注意到在 UniFlash 的“Settings & Utilities“页面上没有可用的函数。

这是否意味着在使用 J-Link 时、无法通过 UniFlash 执行复位或擦除操作、并且仅支持编程和验证？

此致、

Mike

对于 Uniflash、这是正确的。 但是、可以使用执行相同功能的 J-Link 编写脚本。

您好、Brian、

我想问如何使用 J-Link 脚本执行擦除和复位操作。 谢谢你。

尊敬的 Mike：

以下内容包括如何执行恢复出厂设置： 【常见问题解答】MSPM0C1104：如何使用 J-Link 执行恢复出厂设置。

我将与另一个团队成员联系、以获取有关批量擦除脚本的更多信息。

尊敬的 Mike：

您可以使用 Segger J-Flash 软件在器件上执行批量擦除。 J-Flash 用户指南 提供了有关如何执行此擦除以及软件的其他功能的更多信息。

您好、 Brian、

我当前正在使用 J-Link Commander V8.96 执行擦除操作、但我遇到以下错误：

“ 无法擦除扇区 0 @地址 0x41C00000（扇区已锁定）  擦除扇区失败 “

有关更多详细信息、请参阅日志。

您能给我一些建议吗？

谢谢你。

尊敬的 Mike：

这个扇区 是非主存储器的位置、在复位前不应在不对其进行编程的情况下进行擦除。 在复位之前擦除非主闪存而不重新编程将导致器件永久锁定。

在 J-Link Commander 文档中可以找到、 带有“MAP RESET“命令字符串的“EXEC"命令“命令应该会恢复对所有存储器位置的访问。
