Thank you for the report. This does sound like a bug. Are you using
recent sources (such as eCos 3.0)? If not, could you verify that this
issue exists with recent sources please? What type of file are you
loading (ELF, SREC, raw) and how long is it? Which processor and
ethernet part are you using?

The best way to raise formal bug reports is via our Bugzilla system:

  http://bugs.ecos.sourceware.org

This helps to keep all information in one place and to ensure prompt
investigation.
