Ch32v003 debug problems

Hello everyone! I’m trying to set up debug on CH32V003. But it turns out that I only see assembler lines and do not see my code during debugging. How can I achieve that I can see the disassembled code?


platformio.ini

[env:genericCH32V003F4U6]
platform = ch32v
board = genericCH32V003F4U6
framework = arduino
build_type = debug
board_build.core = openwch
monitor_speed = 115200
