Yes, you are right. We want to build a ucLinux system on top of
the EB40. But...
First we tried to get the enclosed ARM SDT(trial) license up and running.
But on all the equipment we have (2 PC's and using two different EB40
our tries to connect the board properly failed.
 Our problem: After running the ARM SDT debugger it connects to the board
and exchanges some data, on most tries this connetion timed out
(after tx/rx about 7000bytes?). But if this task completes, the board timed
after giving it the RUN or Step command.

We tried on comport A at every baudrate (115.2k was listed in our manual)

Any hints ?

As I understand, this board needs some memory upgrade to run ucLinux ?
