Guru Meditation Error: Core 0 panic'ed (LoadStoreError) : a problem of ROM?

[abcdcadb]

I got this error Guru Meditation Error: Core 0 panic'ed (LoadStoreError)

I strongly suspect that it relates to ROM (flash memory) because my app is 0.97 MB while the factory size in partition is 1MB
Any one who is well known about this, could give me advice?
thanks

Without more details it's impossible to know what the problem is. Can you please post more context, or the full output when it crashes?

If the output contains raw addresses then you can use tools like idf_monitor to decode them to line numbers:
