在使用STM32F765上的引導加載程序時使用J-Link調試器時出現的問題

Question

我在ST的Nucleo板上使用了J-Link EDU和STLink調試器。對於測試，引導加載程序代碼存在於0x8000000處，並且跳轉到主要應用程序代碼所在的0x8020000處。當我使用Jlink EDU時，每次成功都無法在0x8020000編程閃存，如果我修改程序並開始調試，Jlink將擦除閃存，但不會成功編程，並且在引導加載程序跳轉後，MCU得到HardFault。無論我使用Jlink還是STLINK（轉換爲Jlink），現在都會發生這種情況。通常我看到它被卡在0xFFFFFFFE。此時，JLINK已經擦除了應用程序代碼，但未能對其進行編程。 有趣的是，當轉換回來並與openocd一起使用時，STlink調試器對於引導加載程序跳轉到主應用程序代碼以及從那裏調試沒有任何問題。 我還發現，如果我通過STLink和OpenOCD將主應用程序代碼編程在0x8020000處，然後切換到JLINK EDU進行調試，只要JLINK不重新編程它就可以工作。如果在日誌中，我看到JLINK閃爍代碼，然後ST從引導加載程序跳轉後崩潰。所以我絕對認爲這與JLINK在調試過程中如何擦除和編程ST有關。 我也嘗試用JLINK指揮官進行編程，這似乎也失敗了。除非我完全擦除芯片。 我使用System Workbench 2.0和GNU ARM Eclipse插件進行Jlink調試，使用最新的ARM工具鏈以及Jlink 616c。我在雙銀行配置中使用閃存中的STM32F765VI。 爲了清晰起見，我還附加了JLINK和STLINK的GDB日誌。我想使用JLINK進行調試，因爲我可以在Eclipse中使用SWO控制檯，而在OpenOCD中它非常麻煩，所以想要解決它。

失敗JLINK調試後，它試圖程序：

Answer 1

我接觸到Segger的傢伙，他們創建了一個wiki頁面，詳細說明如何解決問題。要使Jlink知道STM32F7器件上的Dual Bank配置，必須將Jlink Open Flash加載器與包含Dual Bank配置信息的自定義腳本一起使用。一旦完成，當程序從引導加載程序跳轉到主應用程序時，Jlink調試程序沒有問題。以下是讓Jlink能夠在Dual Bank模式下工作的步驟。

• 首先，使用最新版本的616F起
• 下載和Jlink wiki放置預編譯的二進制（ST STM32F7xxxx_2MB_DualBank.elf）到文件夾包含Jlink.exe和JLinkDevices.xml

• 編輯JLinkDevices。 xml包含與MCU相關的信息，並指示它使用預編譯的二進制文件，而不是Jlink中的默認文件。添加數據庫標籤之下以下的開始： <!-- 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>

• 如果您安裝了JLINK的多個版本，請確保您正在使用的有JLinkDevices.xml編輯使用預編譯的二進制在調試一個會話。

Answer 2

根據第一個日誌，在我看來，J-Link會擦除閃存，然後從地址0x08020000開始對其進行編程 - > no bootloader，並且在0x08000000處執行任何操作 - >跳至hardFault（儘管未找到處理程序在向量表中並且CPU鎖定）。我不是的J-Link的專家，但我們用它在一個類似的工具鏈，具有以下情形：

• 的BSL和應用程序二進制文件使用一個簡單的工具組合並通過的J-Link一起閃現。之後可以通過連接到運行目標來調試任何一個。
• BSL被排除和取代的由「存根」僅執行跳轉到應用

兩個工作得很好。
