Hi, 

 

I intend to set the std-out to the Lancelot VGA. 

Though I have verified the hardware working by a NIOS application program, 

I saw garbage on the screen when I run an application under uClinux. 

 

I guess the writes to controller registers were OK but the access to the SRAM as 

video buffer may have troubles. 

 

Is the current uClinux use the SRAM for some other purpose we don't know ? 

 

RGDS.

So do I. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/unsure.gif  

How can support the lancelot_vga ip core ? 

The uClinux may change the condition in which the lancelot_vga_kit run well. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/cool.gif
