If it's the EP93xx, you'd be well-advised to do so; I gather there is one similar competitor that doesn't waste silicon on a broken FPU, a display engine that can only do up to 800x600x16 or 1024x768x8 without getting jumpy (2.6.2X fbdev), and a raster graphic operations unit that appears to be slower than doing the corresponding bitops in ARM software. Don't get me wrong, the thing still bristles with peripherals and delievers lots of poke for sexto to no energy, and we are working on making the most of what we have. Has anyone tried the NetBSD armevb port on an ep93XX and added the frame driver patch I've seen lurking around? Could its frame buffer do stable higher-res full-colour graphics? The Linux one does them but the frame jitters about, as if the VDU is being locked out of the RAM for too long. > I guess we'll go after our supplier as well to see what availability on the > existing parts will be like Well, leave some for us :) No, it's still a solid chip that runs for hundreds of days without a blip and barely gets warm, so I wouldn't redesign unless you wanted those specific features or are early enough in the design cycle.
