Webserver Woes with mcf5235 (BCC) and rtems 4.7.1

[Ian Caddy]

Hi Christopher,

The fact that the checksums are wrong seems to be an indicator that it 
might be a caching problem.  Do you have write caching turned on?

I think from memory, you are using a Coldfire processor?

Would it be possible to turn off write caching and see if the problem 
goes away?

I hope this helps.

regards,

Ian Caddy
