edit: interesting, what would be the best way to use this if it boot loop and no access to serial port?

I guess not much, but I can display in the Dev sections the last recorded coredump, still usefull for single crashes
Could you add a method to read it in evse_man ?

Not really looked into it, just noticed a warning during crashes.

in the case of bootloop, wouldn't it write forever on the partition ?

We should add a new partition scheme too for the upcoming 16mb flash wifi modules.
I did that for now but not sure it's necessary to allocate this much for the app.
