It works! There seems to be a problem with mmap() function in uClibc. And assert function does not work. It's prety fast for cpu like this:)

Hi top4e,

Could you opening your shematic book and read some sentence how you connected the display controller with the lpc2294 ? :wink:

I'm really interested in this, because i have to realize display connection to a uClinux device like the board from Ulrich!
It would be so nice to have some basic information in how to realize it.
Do you wrote a driver (module) for the display controller? Or does it work over the build in framebuffer driver?

Could you send me please (all?) the information on how to do this great stuff? :wink:

Best regards,
Michael

First software:
There is frame buffer driver for S1D13706 for linux at EPSON Site. But it needs lots of modification to work with uClinux and LPC2294. But it was good startting point. Soon I will post a patch for kernel-2.6.5 for LPC2294 on my site http://uclinux.hit.bg!!!

Hardware:
The S1D13706 supports lots of CPU buses but not AMBA. The connection between S1D13706 with LPC2294 external bus is little strange, but it works with no problem.
Here is the connection:
