C 在STM32F765上使用引导加载程序时，J-Link调试器出现问题

我正在使用ST的NucleoBoards上的J-Link EDU和STLink调试器进行测试，引导加载程序代码显示为0x8000000，然后跳转到0x8020000，其中显示主应用程序代码。当我使用Jlink EDU时，它不能每次成功地将闪存编程为0x8020000，如果我修改程序并开始调试，Jlink会擦除闪存，但不会成功编程，引导加载程序跳转后，MCU会出现硬故障。现在无论我使用Jlink还是STLINK（转换为Jlink），都会发生这种情况。通常我看到它卡在0xFFFFFE。此时，JLINK已擦除应用程序代码，但无法对其进行编程

有趣的是，STlink调试器在转换回来并与openocd一起使用时，在引导加载程序跳转到主应用程序代码并从那里进行调试时没有任何问题

我还发现，如果我用STLink和OpenOCD在0x8020000处编程主应用程序代码，然后切换到JLINK EDU进行调试，只要JLINK没有重新编程，它就可以工作。如果在日志中，我看到JLINK闪烁代码，那么ST在从引导加载程序跳转后崩溃。因此，我肯定认为这与JLINK在调试期间如何擦除和编程ST有关

我还尝试过使用JLINK commander编程，但似乎也失败了。除非我完全擦除芯片

我正在使用System Workbench 2.0和GNU ARM Eclipse插件进行Jlink调试，使用截至目前为止最新的ARM工具链和Jlink 616c。我正在使用STM32F765VI和双银行配置的闪存

为了清晰起见，我还附上了来自JLINK和STLINK的GDB日志。我想使用JLINK进行调试，因为我可以在eclipse中使用SWO控制台，而在OpenOCD中它非常麻烦，所以我想解决它

尝试编程后，JLINK调试失败：

根据第一个日志，在我看来，J-Link删除闪存，然后将其从地址0x0802000编程->无引导加载程序，在0x08000000时无需执行->直接跳转到硬故障（尽管向量表中找不到处理程序，CPU锁定）。我不是J-Link的专家，但我们在类似的工具链中使用它，有以下场景：

• BSL和应用程序二进制文件通过一个简单的工具组合在一起，并通过J-Link闪存在一起。任何一个都可以通过连接到正在运行的目标进行调试
• BSL被排除在外，并被“存根”替换，只跳转到应用程序

---

两者都能完美地工作。

我联系了Segger的同事，他们创建了一个wiki页面，详细介绍了如何解决这个问题。要使Jlink了解STM32F7设备上的双银行配置，必须将Jlink Open Flash loader与包含双银行配置信息的自定义脚本一起使用。完成后，当程序从引导加载程序跳转到主应用程序时，Jlink调试器就没有问题了。以下是让Jlink与STM32F765VI一起工作的步骤，STM32F765VI在双银行中运行
