With the hints from this forum (missing system calls) I got my toolchain to compile the project. However the linker runs into an error with the linker script "region full". (256k Flash, 64k Ram -> which also works fine for my other project). Looks like 7xk are needed :( Did anyone get the application running on a SAM7X256 with the sources available from FreeRTOS? Using WinARM or Cygwin/GNUARM did produce the same errors... My own sample application works fine... any ideas...? Thanks!

Maybe the config/makefile options are set for "run from RAM" so code and
data is placed in the RAM. Check the used linker-script the sequence
after .text { ends with ">ram" if yes, try to change it to ">flash".
