  203.  
  204. So it's not a .config problem or a problem with the extra patches since the failure mode is the same between my evil tree + config and matts tree + omap2plus_config. When you get back to work next week, could you try loading the uimage and dtb from mmc and using mmc as rootfs? I'll try to tftpboot later to see if that makes a difference. And a new toolchain.
  205.  
  206. thanks,
  207.
