Hi Kevin,

I'm not sure why poking didnt make a difference but the upgrade of the SiL
finally got the raw data streaming in.  It's working fine now.

It sounds like you need the latest S1L version to fix this, or add the
pokes I suggested in the previous email. It won't fix tslib if it's not
building correctly though..

Have you seen the lpclinux site?
This link shows how to update to the latest version of S1L:

You can get pre-built binaries for S1L/kickstart here...

I'm trying to activate the TS on the EA LPC3250 and have selected tslib
package. I followed some threads about setting up TSLIB_ variables however
it seems its not the same settings needed by my board. ts_calibrate is an
unknown command. Following is an example of what I get ...

address@hidden /]# Xfbdev -mouse tslib,,device=/dev/input/event0 -mouse mouse &
address@hidden /]# _XSERVTransSocketOpenCOTSServer: Unable to open socket for
_XSERVTransOpen: transport open failed for inet6/nxp:0
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6
(EE) XKB: Couldn't open rules file /usr/share/X11/xkb/rules/base
Couldn't find keyboard driver keybd

Backtrace (1 deep):
0: /lib/ [0x4001312c]

Fatal server error:
Segmentation fault caught

Can't deallocate console 2 errno 16

Thanks for any help,
