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. -- Ing.
