u-boot 配置

CONFIG_CC_OPTIMIZE_FOR_DEBUG=y
CONFIG_LTO=n
 CONFIG_LOG_MAX_LEVEL=9
  • 重新编译.得到u-boot的elf文件(不带后缀就是),可以使用file u-boot确认

e) Note on setting hardware breakpoints for external bus (Example: STM32H735-DK)
GDB is setting breakpoints based on the XML memory map designation of rom or ram, which is hardcoded in st-util for a given processor. However the external bus can be RAM or ROM depending on design.

The STM32H735-DK has external FLASH at address 0x90000000. As a result, because the entire external memory range is ram as it could be either, software breakpoints (Z0) get sent when a breakpoint is created and they never get tripped as the memory area is read only.

JLINK debug

  1. JLINK DEBUG STM32F4
  2. 注意使用"request": "attach",避免烧录elf文件造成错误
