Hi All, I got ATI Radeon Card which is working on PC as Secondary VGA display adapter. When i try this card on my ARM system it is failing to detect the videoram and failing with the following error. radeonfb (0000:00:02.0): Found 0k of SDRAM 64 bits wide videoram adeonfb (0000:00:02.0): cannot map FB radeonfb: probe of 0000:00:02.0 failed with error -5
After some time on google i have found that this error can be solved by running vbetool (which runs the video BIOS). This is completely killing my idea of running it on ARM Board. My goal is to make a VGA Card work on ARM System which doesnt support legacy VGA Address range. Can anyone please clarify me whether this is feasible or not. Anybody have ever tried this kind of setup. Please help me.
