Hi

Running a custom firmware based on SDK 0.9.4 and modified esp-httpd

When I turn off the wifi (whereas the esp was connected), I get :

I get the same exception when I power the module. No idea why.

I've just started getting the same thing. It used to boot fine, now I've not managed to get it to boot at all, it always just gives that error. I've reflashed numerous times, using old code that I'm sure works too.

Did either of you figure out the issue?

Hi

Probably related to hardware issue...
In my case works correctly since I changed the power supply to a better regulated one...
