mdebug
The mdebug image adds Ethernet and wireless download capabilities using
the
Blast
protocol to the Neon
R
. The
SSID
and
DLW
commands above are
only valid when
mdebug
is present.
The following is an example of the use of
mdebug
and
DLW
. Note that
the first commands used download mdebug to address
A1C00000
and run it
from there. Also note that the use of DLW requires a DHCP or BOOTP
server for IP address assignment.
DLW example

JTAG system-level debugger
The jtag executable provided by Boundary Devices is based on the one
provided by the
Open WinCE
project.
Our main goals in developing the jtag program were to aid in hardware
debugging and to allow the first flash EEPROM image to be burned onto
