Thanks! Although I would rather include <stddef.h> where necessary, as it
has has size_t defined.

I had tried doing that, but at the time thought it was causing my section '.text' will not fit in region 'iram1_0_seg' errors. If that wasn't the case, I have no problem switching back to using it and removing this line.

In any case, You may still be interested in merging the ESPD-12 board changes.

you also need adapt the linker file for the new size.

see:
https://github.com/esp8266/Arduino/blob/esp8266/hardware/tools/esp8266/sdk/ld/eagle.app.v6.ld#L8

the iram1_0_seg means the ram segment for code is full but not the flash
you need to use ICACHE_FLASH_ATTR
like here
https://github.com/esp8266/Arduino/blob/esp8266/hardware/esp8266com/esp8266/cores/esp8266/libc_replacements.c#L282
to move functions from ram to flash

Thanks for the info! I'm still new to all this, so still figuring things out. I'll try and get everything working this week.

ok, is the ESPD-12 model identical to the boards sale as ESP-12?
http://www.esp8266.com/wiki/doku.php?id=esp8266-module-family&s[]=esp&s[]=12#esp-12

can you read the marking / naming on the 4MB chip?

It appears that all new ESP-12 modules are actually the 4mbyte ESPD-12 modules, but just not advertised as such. I checked one that I got from a random aliexpress seller about a month ago that was advertised as ESP-12 and its 4 mbyte flash. And I recently purchased 20 ESPD-12 advertised modules from a supplier in alibaba, and that supplier indicated that his supplier no longer has 512kbyte models, and that all were now 4mbyte.

I can't see the flash chip as its under the metal cover, but I checked in software and both modules reported 4 mbyte. I can post the code I used when I get home tonight.

Adding ICACHE_FLASH_ATTR to all of the functions resolved that build issue
