I’ve been struggling to get any application to work in target mode. Even a hello world app was failing to produce any results, I just got:

+WIND: 13

+WIND: 12,0

+WIND: 12,1

+WIND: 13

+WIND: 12,0

+WIND: 12,1

A bit of searching revealed people had upgraded their SDK and had some success so I did this (latest download from wavecome afaik - v04.10) and it changed my problems. If I create a new blank helloworld app and try to build it I get:

C:/OpenAT/IDE/IDE/1.00.06/mak/gen.mak:124: /cygdrive/C/OpenAT/IDE/IDE/1.00.06/sgt/mak/makegen.mak: No such file or directory  
c:\OpenAT\IDE\MINGW\3.8.0.1\bin\make.exe: \*\*\* No rule to make target `/cygdrive/C/OpenAT/IDE/IDE/1.00.06/sgt/mak/makegen.mak’. Stop.

```
Launch a full library or binary process

```

C:/OpenAT/IDE/IDE/1.00.06/mak/gen.mak:124: /cygdrive/C/OpenAT/IDE/IDE/1.00.06/sgt/mak/makegen.mak: No such file or directory  
c:\OpenAT\IDE\MINGW\3.8.0.1\bin\make.exe: \*\*\* No rule to make target `/cygdrive/C/OpenAT/IDE/IDE/1.00.06/sgt/mak/makegen.mak’. Stop.  
Done.  
[wmmake error #1] Build error.

If I run an existing ‘hello world’ I had I actually get AT responses (but no traces despite init target, safe target etc etc) but any changes I make in the code don’t update the DWL file and I get the above error message in the build although it just says it’s a warning not an error

I’m using the “.dwl” file not the “.wpb.dwl” which I think is correct?

As an aside (possibly linked?), the workspace in GCC\OUT\TMT makes the TMT bomb out with some unhandled exception

Any help greatly appreciated
