OK some more information...
The segfaults doesn' happen always.
I'm not sure when it happens though.
But if lsmod doesn't break it seems apt-get and mount breaks
Bottom line: something somewhere will break :(
I've now done some tests with /dev/ttts5 and a scope.
When I program my own code it works fine :)
When I install tsuart1 and tsuart7800...
I'm not sure .
echo "bla bla" > /dev/ttts5
does produce output. But the baud rate is horribly wrong.
I've installed the "setserial" program. And according to it's feedback
the baudrate is set.
But it doesn't make a difference on the output.
What I've also done is connect my serial program to COM3 port.
Since ttts4 should be the normal COM on that.
Well I see output on the PC.
But it is garbage regardless of what I do.
I've tried different settings with gtkterm as of baud rate and flow
control ect.
No help
From the scope output it seems the baud rate should be around 10000
more or less.
Well setting that in gtkterm doesn't help. Maybe I'm doing something
else wrong.
And I think I'm going to smother the whole board with silicon to stop
myself accidently shorting random things :)
Has this file:
ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7800-linux/sources/linux-2.6.21-ts-src-jan182008.tar.gz
Got the newest source code for that driver?
Anybody else having problems with this driver?
Or is it just me?
