我正在使用来自ST的nuclea板上的J-Link EDU和STLink调试器进行测试，bootloader代码显示为0x8000000，而主应用程序代码显示为0x8020000。当我使用Jlink EDU时，它不能每次成功地将flash编程为0x8020000，如果我修改程序并开始调试，Jlink会擦除flash，但不会成功地对其编程，并且在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已清除应用程序代码，但未能对其进行编程。
有趣的是，当STlink调试器被转换回来并与openocd一起使用时，bootloader从那里跳转到主应用程序代码并进行调试没有任何问题。
我还发现，如果我用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。
我还试着用JLINK commander编程，但似乎也失败了。除非我完全清除芯片。
我使用System Workbench 2.0和GNU ARM Eclipse插件进行Jlink调试，使用截至目前最新的ARM工具链和Jlink 616c。我使用STM32F765VI和双列配置中的闪存。
为了清楚起见，我还附加了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中则非常麻烦，所以我想解决这个问题。
尝试编程后JLINK调试失败：

最佳答案
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。为了让Jlink知道STM32F7设备上的双银行配置，Jlink Open Flash loader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，Jlink调试器在程序从引导加载程序跳转到主应用程序时没有问题。以下是让Jlink使用在双银行模式下运行的STM32F765VI的步骤。
首先，使用616f以后的最新版本
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。在开始处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>
如果安装了多个版本的Jlink，请确保使用的是已编辑其JLinkDevices.xml的版本，以便在调试会话中使用预编译的二进制文件。
