Hello,
I tried with the GDB debugger and seems to work.
How is possible, instead, that the command write flash of openOCD
doesn't work?
Hi,
When GDB loads, a default hook calls "reset init" to get the target
into a well defined state and prepare clocks for faster programming.
If you flash "manually", you should make sure to have called "reset
init" yourself. Then it should be equivalent.

When we luanch openOCD server with this script:
# default ports
telnet_port 4444
gdb_port 3333
tcl_port 6666
init
reset init
doens't work and the the result is:
