I installed Eclipse with esp-idf on Linux Mint
I successfully built the Blink example.
But after flashing to the ESP-Wroom-32 board I see a message in the terminal:
"--- 0x40080400: _invalid_pc_placeholder at ...."
What does this mean?
How do I fix this error?

This error occurred in esp-idf-v5.5-dev.
In the stable version esp-idf-v5.4 - everything is ok.

That is unlikely to be the error - it's the monitor program seeing something that looks like a PC value and helpfully decoding it for you.

Hi i have same issue with esp 5.5 stable, is there any workaround to somehow delete this line from bootloader? i see that is no error but esp bug in this version, rollback to 5.4.2 not make sense.

The 'error' is the monitor program trying to be helpful, looking up the symbol for address 0x40080400. It's harmless and probably unrelated to the issue you're seeing.

I agree that it looks like an error and should be removed, this message is misleading and not helpful at all.
