If your hijacking this thread you should at least hint that I may try to use your ROM symbol project
to generate a stub to answer my original question

Please both of you stay at the technical topics and try to make postings understandable.
Knowing a world before twitter I need something like this to follow a posting:

use ROM symbol project to generate a stub to answer my original question

by dropping .incbin "bootrom.bin" from bootrom.s and getting empty object with symbols? That's neat. And that may work if linking is arranged appropriately, i.e. bootrom.o is linked as an object file, not as a part of library.

Regarding thread hijacking: I'm sorry. I'm really annoyed by the rants this guy posts and I'm only pointing at definitely false statements.

Any idea how to make the linker use the ROM firmware symbol?

ESP8266 ROM and EspressifSDK code use Xtensa Compiler Version 8.0.1 RC-2010.1-win32 lx106, libc.a libgcc.a ver 2.8 (?)
UDK (My Espressif DevKit for Windows + Eclipse IDE) use gcc-4.8.2, libgcc GNU AS 2.24.

- Sat Jun 06, 2015 10:33 am #19656 Are the calling sequences and register usage of the two compilers the same? I.e. is it even possible to call the xtensa compiled code from gcc compiled code?
