Dear friends, I am trying to use KEIL IDe for debugging my target(ARM). I want to write my own DLL to interact with my hardware. For that i have downloed 1). gccarm322b.exe 2). ekarmv06.exe and 3). apnt_173.zip , apnt_173.chm I have exactly followed all the instructions. 1). My first problem is that Cygnus installation is not creating the shortcut properly for sys-include file. 2). If i point to c:/cygnus/arm-tools/include, i will get error compiling application in KEIL IDE. 3). As it has been mentioned in the app note, i am not finding "measure" project. There are two "measure" application udner "Ads" as well as "Gnu" folders. I am selecting "Gnu/Measure" folder. When i "Rebuild All project files", i am getting error saying stdlib.h not found. Double clicking on error message, i am getting c:\cygdrive\c:\Cygnus\.... As per my knowledge, it should be /cygdrive/c/cygnus/ Can anybody help me by telling how to overcome from it? thanks & regards vadiraj
