X windows for Linux PPC embedded

X windows for Linux PPC embedded

[Jan Damborsky]

Hello guys,

I would like to ask, if there is some project
for porting X windows system to Embedded
PPC Linux. I use board with MPC823E with
VGA TFT display+touch screen, 32MB RWM,
4MB FLASH, Ethernet, serial RS232,....
I would like to use it as remote graphic terminal
communicating via Ethernet by means of X protocol.
Does somebody know how to make it work ?

                                                                 HANYS

There is nothing much to "port". Just use a system with  as  much  as
possible RAM, and a local harddisk, so you can enable swap space, and
run the standard "make" procedure on the target (native!).

I once looked into this trying to find out if you could prepare X11R6
for cross compilation, but found it too difficult  /  not  worth  the
effort.  I  ran  a  build  on  a  MPC860P  with 64 MB RAM and a 20 GB
harddisk attached to the PCMCIA slot. It took  _ages_  (>  48  hours,
IIRC)  but  except  for  some  minor issues the build went through. I
think this was in the  age  of  HHL  1.2  JE,  so  any  decent  build
environment should work fine, too.


Best regards,

Wolfgang Denk

There is nothing much to port.  Few months back I had cross-compiled TinyX
successfully for a MPC860 board on x86 platform.
Except the proprietary touch screen interface(we added this ourself),
everything else worked fine on the target framebuffer device.  But I haven't
tried the complete X.
I hope this information is useful for you.


Best regards,

Thank you for your information. We have 32M of DRAM, 16M of FLASH on board.
Do you think it is sufficient for make tinyX working?

It is more than enough.  We had 16M of DRAM and 16M of FLASH on the target.

Could you send me please appropriate link to TinyX source tree
you successfully used for building working X ?
       Thank you, HANYS
