SPIFFS writing broken esp-01

[spider0404]

There is a new batch of esp-01 whit different chip, whit them you can't write on SPIFFS, can't upload web-ui. You can upload web-ui with arduino ide but when you try to write on it put macro or something else. Web-ui is gone blank page or page saying you are missing index......gz

There is a patch so everything is working as expected.

This is not ESP3D bug but without this patch ESP3D doesn't work :)

This is written here so somebody else doesn't lose time.

Thanks for pointing out -yes the puya chip is not yet well supported by default

To enable the patch , search for esp.h in core, there is the switch to enable the patch with latest git of the core

#ifndef PUYA_SUPPORT
  #define PUYA_SUPPORT 0
#endif

Change to

#ifndef PUYA_SUPPORT
  #define PUYA_SUPPORT 1
#endif

another solution:
Create platform.local.txt in esp8266 core directory and add these lines:

compiler.c.extra_flags= -DPUYA_SUPPORT=1
compiler.cpp.extra_flags={compiler.c.extra_flags}

like explained here esp8266/Arduino#5504 (comment)

Now patch is enabled in core by default
