you need a line like

adapter_khz 1000

in your board description file

不懂openocd太坑了。。。。
加上这句就好了

echo "WARNING: boards/esp-wroom-32.cfg is deprecated, and may be removed in a future release."
set ESP32_FLASH_VOLTAGE 3.3
source [find target/esp32.cfg]
adapter_khz 1000

esp-wroom-32.cfg

jlink调试的选项
-s ${openocd_path}/share/openocd/scripts -f interface/jlink.cfg -f board/esp-wroom-32.cfg

感谢总结。
