c - 在 STM32F765 上使用引导加载程序时 J-Link 调试器出现问题

转载作者：太空宇宙更新时间：2023-11-04 03:22:01

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会删除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 已删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 对 0x8020000 处的主要应用程序代码进行编程，然后切换到 JLINK EDU 进行调试，只要 JLINK 不对其进行重新编程，它就可以正常工作。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在调试期间如何删除和编程ST有关。

我还尝试使用 JLINK commander 进行编程，但似乎也失败了。除非我完全删除芯片。

我正在使用带有 GNU ARM Eclipse 插件的 System Workbench 2.0 进行 Jlink 调试，使用截至目前最新的 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，所以想解决它。

尝试编程后 JLINK 调试失败:

最佳答案

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，使用从 616f 开始的最新版本
从 Jlink wiki 下载并放置预编译的二进制文件 (ST STM32F7xxxx_2MB_DualBank.elf)到包含 Jlink.exe 和 JLinkDevices.xml 的文件夹
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:  <Device><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" /> </Device>
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 session 中使用预编译的二进制文件。
