在 STM32F765 上使用引导加载程序时 J-Link 调试器出现问题
Issue with J-Link debugger while working with bootloader on STM32F765
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，引导加载程序代码位于 0x8000000 处，并跳转到主要应用程序代码所在的 0x8020000 处。当我使用Jlink EDU时，每次都无法成功烧写0x8020000处的flash，如果我修改程序并开始调试，Jlink会擦除flash但烧写不成功，bootloader跳转后，MCU获取 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已擦除应用程序代码但无法对其进行编程。
有趣的是，转换回 STlink 调试器并与 openocd 一起使用时，引导加载程序跳转到主应用程序代码并从那里进行调试没有任何问题。
我还发现，如果我通过STLink和OpenOCD在0x8020000处编写主应用程序代码，然后切换到JLINK EDU进行调试，只要JLINK不重新编写它就可以工作。如果在日志中，我看到JLINK刷写了代码，那么ST在从bootloader跳转后崩溃了。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，但似乎也失败了。除非我完全擦除芯片。
我正在使用带有 GNU ARM Eclipse 插件的系统 Workbench 2.0 进行 Jlink 调试，截至目前最新的 ARM 工具链和 Jlink 616c。我在双组配置中使用带闪存的 STM32F765VI。
为了清楚起见，我还附上了 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 擦除闪存，然后从地址 0x08020000 对其进行编程 -> 没有引导加载程序，在 0x08000000 处没有任何可执行的 -> 直接跳转到 hardFault (尽管在向量 table 中没有找到处理程序并且 CPU 锁定了）。我不是 J-Link 的专家，但我们在类似的工具链中使用它，场景如下：
- BSL 和应用程序二进制文件使用一个简单的工具组合在一起，并由 J-Link 一起闪存。之后可以通过连接到 运行 目标来调试其中任何一个。
- BSL 被排除并替换为 'stub' 仅跳转到应用程序
两者都完美无缺。
我联系了 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。为了让 Jlink 了解 STM32F7 设备上的双银行配置，Jlink Open Flash 加载程序必须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 在 Dual Bank 模式下运行的步骤。
- 首先，使用 616f 以上的最新版本
- 从 Jlink wiki 下载预编译的二进制文件 (ST STM32F7xxxx_2MB_DualBank.elf) 并将其放置到包含 Jlink.exe 和 JLinkDevices.xml
的文件夹中
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。在开始的数据库标签下添加以下内容：
<!-- 该条目将覆盖 J-Link 软件中现有的设备条目，因此自定义闪存算法用于内部闪存 -->
<设备><br>
<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" />
</设备>
如果您安装了多个版本的 Jlink，请确保您使用的是已编辑 JLinkDevices.xml 的版本，以便在调试会话中使用预编译的二进制文件。
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，引导加载程序代码位于 0x8000000 处，并跳转到主要应用程序代码所在的 0x8020000 处。当我使用Jlink EDU时，每次都无法成功烧写0x8020000处的flash，如果我修改程序并开始调试，Jlink会擦除flash但烧写不成功，bootloader跳转后，MCU获取 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已擦除应用程序代码但无法对其进行编程。
有趣的是，转换回 STlink 调试器并与 openocd 一起使用时，引导加载程序跳转到主应用程序代码并从那里进行调试没有任何问题。
我还发现，如果我通过STLink和OpenOCD在0x8020000处编写主应用程序代码，然后切换到JLINK EDU进行调试，只要JLINK不重新编写它就可以工作。如果在日志中，我看到JLINK刷写了代码，那么ST在从bootloader跳转后崩溃了。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，但似乎也失败了。除非我完全擦除芯片。
我正在使用带有 GNU ARM Eclipse 插件的系统 Workbench 2.0 进行 Jlink 调试，截至目前最新的 ARM 工具链和 Jlink 616c。我在双组配置中使用带闪存的 STM32F765VI。
为了清楚起见，我还附上了 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 擦除闪存，然后从地址 0x08020000 对其进行编程 -> 没有引导加载程序，在 0x08000000 处没有任何可执行的 -> 直接跳转到 hardFault (尽管在向量 table 中没有找到处理程序并且 CPU 锁定了）。我不是 J-Link 的专家，但我们在类似的工具链中使用它，场景如下：
- BSL 和应用程序二进制文件使用一个简单的工具组合在一起，并由 J-Link 一起闪存。之后可以通过连接到 运行 目标来调试其中任何一个。
- BSL 被排除并替换为 'stub' 仅跳转到应用程序
两者都完美无缺。
我联系了 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。为了让 Jlink 了解 STM32F7 设备上的双银行配置，Jlink Open Flash 加载程序必须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 在 Dual Bank 模式下运行的步骤。
- 首先，使用 616f 以上的最新版本
- 从 Jlink wiki 下载预编译的二进制文件 (ST STM32F7xxxx_2MB_DualBank.elf) 并将其放置到包含 Jlink.exe 和 JLinkDevices.xml 的文件夹中
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。在开始的数据库标签下添加以下内容：
<!-- 该条目将覆盖 J-Link 软件中现有的设备条目，因此自定义闪存算法用于内部闪存 --> <设备><br> <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" /> </设备>如果您安装了多个版本的 Jlink，请确保您使用的是已编辑 JLinkDevices.xml 的版本，以便在调试会话中使用预编译的二进制文件。
