I believe the lancelot core is Avalon compatible, so that is what he is probably using. Regarding the driver, there is no driver for it yet - on your board, do you have a separate video buffer, or is it all run from the same RAM (SDRAM, DDR?). If you don't have separate video memory, like SRAM, running linux and video at the same time will be very difficult. And as hippo mentioned, you still need a framebuffer driver..

hi all,

thanks for the interest and reply,

YES, lancelot core is Avalon compatilbe, I am using the same and I agree there is need for porting frame buffer driver for same, at present I am doing the feasibility study (going through other frame buffer driver present in uclinux) to do so.

The example C code given by lancelot www.fpga.nl site, looks like it runs from SDRAM.

Once I finish with the study I will update all,

thanks,

Ankur
