This section will describe several common problems users have encountered when using gdl, and their solutions.
This is by far the most common error message, and means that after downloading the bootstrap loader, gdl was unable to synchronize with the HC11. The reason this error is so common is that this is the earliest stage in the downloading process at which a problem can be observed, and nearly all hardware problems manifest themselves by the HC11 simply not responding to gdl. So gdl can't give a more informative message; all it knows is that the HC11 isn't talking.
The following are some of the problems which have been observed to manifest themselves with this error. You'll probably feel insulted by most of these suggestions... but I've wasted a lot of time myself by not checking them, so I'll mention them.
HC11 not turned on.
HC11 not in download mode (remember, it's necessary to reset the HC11 before each download).
Serial cable not on the serial port specified in the Preferences property box.
Gdl will only display serial ports that you are able to read from and write to. If you don't see any ports displayed, it means you can't get access to any.
Your system administrator will need to give you access to the serial ports, most likely by changing the protections on the ports.
Gdl will only display files ending with .s19, which you are able to read. If you aren't seeing any, there aren't any; either the file name is wrong or you don't have read access to the file.
5. I get error messages saying ``Gtk-CRITICAL **: file gtkwidget.c: line 1589 (gtk_widget_map): assertion `GTK_WIDGET_VISIBLE (widget) == TRUE' failed'' when the program starts up.
Short form: don't worry about it.
Long form: One of the widgets I use (the directory tree widget, used in the port and file selection boxes) tries to display itself when the program opens a directory when the program is first started. It isn't visible yet, so the toolkit complains. It's annoying, but harmless.
