Stm8 inspect memory fails - [sizedata] Assertion error

I am unable to get the inspect memory working on Ubunti platform. Everything builds fine, both realease and debug (although cannot get debug to do anything with stlinkv2, a different issue) and can also upload OK.

I have the latest pio core (5.1.1) and everything appears up to date.

When I try to run inspect memory form pio home, I just get this output:

PIO Core Call Error: "Processing Mi80_104_debug (platform: ststm8; board: stm8s003f3; framework: spl)

Seems tool is throwing python [sizedata] Asserion Error. If anyone has any insight into this, help is much appreciated.

Please report this to Issues · platformio/platform-ststm8 · GitHub.

There are known limitations and bugs with debug symbols in ELF files stemming from SDCC bugs at the moment (e.g. Debugging not working with Arduino examples · Issue #48 · platformio/platform-ststm8 · GitHub) so maybe that plays a part in the memory analysis here.

ok will do - thanks for the help
