EDB7xxx are the evaulation boards from Cirrus Logic which support their EP7xxx chipsets. If you build a different board (i.e. platform in eCos parlance), you'll need to tweak the platform support. This may be only as hard as a few lines of change (which is why we have a single "platform" for a number of their boards - they are all quite similar), or as hard as cloning a new platform if there are a number of differences. > Also look at hal_platform_extras.h. > > Jifl
