Mbed OS Studio 调试器 (pyOCD) 写入错误的固件地址时出错

Question

尝试在 STM32H743VITx 设备上加载调试目标时收到错误

:WARNING:builder:Chip erase used when flash address 0x8020000 is not the same as flash start 0x8000000

。这会在调试会话期间覆盖引导加载程序并使固件崩溃。

。我在 custom_target json 中设置了正确的 mbed_rom_start ，并且构建和加载发布版本确实会正确闪烁，但之后会在某个地方崩溃。这就是我尝试运行设备上调试器的原因。问题是 pyocd 闪存擦除使用 0x80000 作为闪存地址，而不是 0x8020000。

"bootloader_supported": true,
"mbed_rom_start": "0x8020000",
"mbed_ram_size":  "0x100000",
"mbed_size":      "0x200000",
"mbed_ram_start": "0x20000000",

是否有办法配置调试目标以使用正确的地址？我还做错了什么吗？我尝试将基地址添加到调试标志，但启动服务器时出错。

--target STM32H743VITx   --erase=chip --frequency 1800000 --pack '/Library/Application Support/Mbed Studio/mbed-studio-tools/cmsis-packs/Keil.STM32H7xx_DFP.2.7.0-small.pack' -O connect_mode=under-reset

我还尝试使用

 更新 

STM32H743VITx

 中的 

./mbed-os/tools/arm_pack_manager/index.json

目标

    "algorithms": [
        {

MBED 网站上对此进行了记录，对于带有引导加载程序的设备，需要使用

erase=sector

而不是芯片。
