There was once a problem with the EBSA285 setup of the SDRAM
controller. The controller had been initialised for 1/2 the actual
memory. This resulted in the top address line being left to
float. Most of the time it floated one way, but occassionally, it
floated the other way, and so it seemed to forget things.....

See if you can make packages/hal/arm/ebsa286/current/tests/sdram0.cxx
work on your target. Also try running the
packages/hal/common/current/tests/cache.c
