Hi Jonathan,

I found that the gdb-stub module for the AEB rev.C, provided with eCos,
doesn't work at 9600 baud.

In addition, when I tryed at 38400 baud, the connection failed because the
serial port configuration that I made on the
AEB board was not correct. In effect, two environnement variables must be set
to change the baud rate properly,
that is, you have to give the following commands at the prompt of the
bootstrap loader:

boot: setenv baud 38400
boot: setenv noautobaud

With this settings, everything seems to work correctly. (Also if I don't see
the output string ++$T01... that you
mentioned, when connecting the board directly to minicom, or other terminal).

Andrea.
