Debugging
Debugging of Lightning LN882x chips is possible and was tested with a JLink probe on OpenOCD and JLinkGDBServer.
(the following is applicable to Arduino framework, and was not tested with SDK framework)
LibreTiny has ready-to-use OpenOCD config files:
Local debugger
It should be possible to use PlatformIO's built-in debugging capabilities directly, when plugging an OpenOCD-compatible debugger into your PC. As there are no debugger interfaces built into these IoT boards, you need to specify your interface of choice in platformio.ini:
[env:my_board]
openocd_interface = <interface name>
where <interface name> is for example raspberrypi2-native, stlink, etc.

Technical details
GDB is first configured with mem 0x0000000 0x1000000 ro in order to mark flash memory as read-only. This makes GDB use hardware breakpoints, as software BPs don't work on these boards.
