No Output on Console Port
The eZ80190 Development Kit is shipped with a Flash Loader utility that
is loaded in the protected boot sector of Flash memory (U3). Upon power-
up of the eZ80Acclaim!
®
Development Platform and the eZ80 Web-
server-i E-NET Module, the eZ80190 device on the module starts running
code from this Flash memory area. This code enables the Console port
with settings of 57.6 kbps, 8, N, 1.
The Console checks the Receive buffer. If a space character is received on
the Console port, the Flash Loader utility is enabled and a boot message
should be displayed on your connected device. If no message is displayed,
check the following:
•
Jumper J2 must be ON (IrDA is disabled)
•
On Connector J6, the jumper must be removed from pins 6 and 9 (pin
names con_dis and GND).
