我正在使用ST的Nucleo板上的J-Link EDU和STLink调试器。为了进行测试，引导加载程序代码出现在0x8000000处，并且只是跳转到0x8020000，其中存在主应用程序代码。当我使用Jlink EDU时，它不能每次成功编程闪存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，并且在引导加载程序跳转后，MCU得到HardFault。现在，无论我使用Jlink还是STLINK（转换为Jlink），都会发生这种情况。通常我看到它停留在0xFFFFFFFE。此时，JLINK已删除应用程序代码，但未能对其进行编程。
有趣的是，转换回来并与openocd一起使用的STlink调试器没有任何问题，引导加载程序跳转到主应用程序代码并从那里进行调试。
我还发现，如果我通过STLink和OpenOCD将主应用程序代码编程为0x8020000，然后切换到JLINK EDU进行调试，只要JLINK不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从引导加载程序跳转后崩溃。所以我肯定认为这与JLINK在调试期间如何擦除和编程ST有关。
我也试过用JLINK指挥官编程，这似乎也失败了。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，使用截至此日期的最新ARM工具链和Jlink 616c。我正在使用STM32F765VI和闪存双库配置。
为了清楚起见，我还附加了来自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：

我找到了Segger的人，他们创建了一个wiki页面，详细说明了如何解决这个问题。要使Jlink知道STM32F7器件上的双Bank配置，Jlink Open Flash加载器必须与包含Dual Bank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调试器没有问题。以下是使Jlink与在双库模式下运行的STM32F765VI一起使用的步骤。
编辑JLinkDevices.xml以包含与MCU相关的信息，并指示它使用预编译的二进制文件而不是Jlink中的默认二进制文件。在开头的数据库标记下添加以下内容：
<!-- This entry will overwrite the existing device entry in the J-Link software, so that a custom flash algorithm is used for the internal flash -->
<Device>
<ChipInfo Vendor="ST" Name="STM32F765VI" Core="JLINK_CORE_CORTEX_M7" />
<FlashBankInfo Name="Internes Flash" BaseAddr="0x08000000" MaxSize="0x00200000 " Loader="ST_STM32F7xxxx_2MB_DualBank.elf" LoaderType="FLASH_ALGO_TYPE_OPEN" />
</Device>
如果您安装了多个版本的Jlink，请确保您使用编辑了JLinkDevices.xml的版本在调试会话中使用预编译的二进制文件。

根据第一个日志，在我看来，J-Link擦除闪存然后从地址0x08020000开始编程 - ＆gt;没有引导加载程序，并且无法在0x08000000执行 - ＆gt;跳转到hardFault（尽管在向量表中找不到处理程序且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，具有以下场景：
两者都完美无缺。
