I verified that SRESET on the BDM connector is pulled up (on the
schematic). I tried to pull up it with a wire but it doesn't work. It
only works if I connect a 10 cm wire to SRESET pin on the BDM connector
without connecting the other side of the wire (Probably it gets some
electromagnetic noise). The board starts and remains working if I remove
the wire, tehn, if I give a reset on the u-boot, the board hangs again.

Strange behaviour!!
Bye,
Antonio.
