How to fix error "Failed to dump SPI flash from device. Verify debug connection and try again." when using st-link v2.

When you using openocd build by yourself, the error "Failed to dump SPI flash from device. Verify debug connection and try again." will occur when backup the SPI flash. The reason is "hla_swd" has been deprecated in current version OpenOCD ("dapdirect_swd" as a replacement for the "hla_swd") , it will failed if you try to connect to the device. Replace the "hla_swd" to "dapdirect_swd" in file "game-and-watch/openocd/interface_stlink.cfg" then everything works fine.
