The call_user_start symbol is missing; either it has been renamed in the SDK, or it is missing due to an incorrect link. See also #24.

I'm thinking of adding a command line argument to specify the entry point name and/or adding a list of entry point names to look for.

this is my try (line 352)

try:            
    self.symbols[fields[2]] = int(fields[0], 16)
except ValueError:    
    print fields

and the output:

['U', 'os_intr_lock']
['U', 'os_intr_unlock']
``

I found thats not necessarily the "call_user_start" symbols thats missing but
sometimes missing symbols didn't make the linker fail.
You see that is the case here, too: os_intr_lock is missing here
Can't see a pattern when they get through the linker.
When doing an "nm" on the image you see the unresolved symbols.
In this case I guess I know the reason for the problem.
Unfortunately nodemcu stuff does not compile with -Wall and so it does not warn on missing prototypes but just guesses one.
SDK 1.0.1 has defines for os_intr_lock etc. that map to (from memory) ets_intr_lock.
Those defines are gone for SDK 1.1.0 and so the linker looks for the functions os_intr_lock.
I added a compat header that has those defines.

I think the entry symbol name issue is fixed as of a0c18ea, so I'm going to close this issue. If you think I missed something then please reopen it.

It's working now, thanks
