如题，使用stm32cubeide通过h7-tool给stm32l4r9下载程序失败。使用mdk下载是正常的。
STM32CubeIDE默认不支持DAP的，但是通过ST-Link（OpenOCD间接支持），选择连接到远程GDB服务器端口，参考如下：https://www.cnblogs.com/pathfinder-world/p/13943911.html
但实际使用出现如下错误信息：
Info : auto-selecting first available session transport "swd". To override use 'transport select <transport>'.
Info : DEPRECATED target event trace-config

网上有类似的错误http://vedder.se/2012/12/debugging-the-stm32f4-using-openocd-gdb-and-eclipse/，加额外的命令如：
target remote localhost:3333monitor resetmonitor haltmonitor flash protect 0 0 11 offmonitor flash write_image erase "/path/to/hex/file" 0 ihexdisconnecttarget remote localhost:3333monitor resetmonitor halt
尝试发现还是不行，想了解下硬汉大哥有没有做stm32cubeide下的下载测试或有什么解决思路，多谢。
