Hello Again,
As I have found some time to start again with LV Emb I would ask more experienced users.
My setup is:
Gnu toolchanin build and used under Cygwin
ARM7 LPC2148 Ev Board
LV Emb dev module
I can build and run small application (c one) on dev board with toolchain but now I wish to use it with
Thank You in Advance

Hello again,
Tank You for previous answer. Idd gcc runs without problems. Now I stuck on linker errors:
One of them is:
LVBlockDiagram.c:(.text+0xcc): undefined reference to `memmove'
Strange thing is that my “string.h” doest not contain definition for memmove (and that already explains my error), any idea how can I recover form this problem??
My prev eCos kernel configuration was not supporting dynamic memory allocation therefore I got much more complains about *mem*. Is there some way to force on LV C code generator to not use certain functionalities? (like this memory allocation)

Hello Again,
Seems like i wanted to be smarter than you guys are:) My problem was that in project manager i gave to seperate tools for compile link strip and objcopy. then i didnt care about flags anymore. So thank you pjtanz for you last question....that was the key. thank you Michael for your time and patience!

New Issue...
I've installed Red Boot on LPC2148 developement board. After compilation debug.vi starts loading application (which is 171kb) but downloading stops after 32kB. That is exactly amount of RAM memory in controller. So I suppose this behaviour is correct. Is that true that LV runtime library makes 171kb of programm? If so, is there a way to make just tiny demonstration programm that is using while loop and iteration controll?? (now i uderstand why size of ram should be at least 256kb)
