I've got a strange problem where the ESP-HTTPD example seems to run just fine on my ESP-07 boards, but on my ESP-12 boards I get the following error:

Code: Select all

Ready
mode : null
Fatal exception (28):
epc1=0x40240550, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000

I've made no modifications to the project yet, just compiled and flashed using esp-open-sdk.
Any idea why the two modules would behave differently with this project?

Alright I did manage to get the ESP-HTTPD example working with the ESP-12 modules. Instead of using "make flash" and "make htmlflash" I used nodemcu-flasher (with the binaries set properly in the Config tab) and changed the flash size to 4MByte under the Advanced tab.

Hey

I'm having the same problem.
Could you list the config ? I can't seem to get it right.
Or take a screenshot of this ?
It would help me A LOT !

Thanks

Hmm, it may have something to do with the 4MB of flash; the standard esphttpd example compiles for a 512KB flash making the flash bit where the SDK expects the WiFi parameters to be end up wrong. Does a 'make blankflash' do anything for you?
