Hello janhendrik,
Thanks for the tip with the path. My mistake was to write "$PATCH" in lower cases! Now is working fine.
$ $PATH
bash: /cygdrive/d/quartus41/niosII10/components/ecos/ecos-2.0/tools/bin:/cygdriv
e/d/quartus41/niosII10/components/ecos/ecos-2.0/packages/hal/nios2/tools/bin:/bi

I did also a failure when trying to upload the flash file. Now it would work but I had to give the development board back to Altera. Tomorrow I will try to get it work with my own hardware. There are some differences to the DK.
