[En-Nut-Discussion] IJG jpeg decompression problem

  I'm trying to use Ethernut (on a SAM7X256-EK) with IJG's jpeg
  decompression code (ijg.org).  It kind of works but the process of
  decompressing a very small 16x16 pixel test image, which does generate
  the correct output, screws up NutNet in such a way that any subsequent
  call to NutUdpReceiveFrom or NutUdpSendTo immediately crashes
  the processor without an error message.  At the point just prior
  to crashing NutHeapAvailable() reports 27KB of free memory.

  I wonder if anyone else has attempted to use the IJG code or can
  give me some pointers on what might be going wrong.  I'm new to
  Ethernut and the Yagarto Tools and am inexperienced in C
  programming so please be gentle.

  Your help is much appreciated.

Best Regards,
