Re: [ts-7000] Frame Buffer Programming ?

[Matthew Saint <>]

Hi, the board is the TS-7KV daugher board thats pluging into the TS-7200 board. Which manual are you using? I cant find the address reference.

 

The downloadable binary bitblt runs fine even if the video console is active so i dont think is the problem. But i will try on Monday now.

 

Thanks

 

Matt

Hello,

> any idea where its documented that 0x21800000 is the video base addr?

After looking at the manual I realized the address I gave you is for the
video memory on the TS-7KV. Sorry about that. The address for video
memory on the TS-7300 is 0x72200000. Try commenting out the getty running
on the virtual console before running the bitblit demo...
