Sorry for the extremely long pause here. I was side tracked to another
project for a couple months.
Anyway, here are the details of my build:
My target is a Marvell PXA320 (armv5tel) running Debian Squeeze. I am
building natively with GCC 4.4.5.
I am using the following source (diff for microwin is attached):
micrown (Nano-X)
nxlib latest git source
LibVNCServer-0.9.9
freetype-2.4.8
I have diff files available, however my first attempt to send this
email was rejected as exceeding 3K bytes, so I am resending without
them. The diffs contain changes to get VNC to link properly, but also
some customization for my application (paths, no VNC passwd, version
timestamp, UTF-8 support and debug messages)
VNC is connecting and mostly working. The issue I have is small screen
image changes do not get updated. The only way to get those changes is
to wait for a large change or hit the refresh button on the VNC client.
Any guidance here is appreciated. I am willing to do the grunt work, but
don't have an idea where to start.
Thanks much,
Pete Klemm
