I doubt they're running the same version of U-Boot, but I don't know the version numbers offhand. Check the display setup. In my case, my old U-Boot (which works great) was using dvimode=1024x768-24@60 and the new U-Boot is using dvimode=1024x768MR-16@60 When I switch back to the old setting, even with the new U-Boot, my display runs great again. n.b. this may be kernel revision sensitive as well. > >> BTW - why did you send your original query to the Poky list? > > Because Darren suggested that I do so, to get various eyes on it :-) Sounds reasonable - I only asked because your original email didn't really spell out why it went to the Poky list.
