I'm currently working with the iMX50 EVK. I'm using ltib on the Ubuntu VM (provided by Freescale) to build Linux and u-boot, and I'm booting from an SD card. The problem I'm having appears to be isolated to u-boot. I do not get any network support when I boot with a u-boot binary created using the Ubuntu VM. I'm just booting into u-boot at this point. I do have full network support when I boot using the SD card provided by Freescale (it contains the u-boot binary loaded by Freescale with a kernel and rootfs I created). I've tried everything to get the u-boot binary I'm building to work. Has anyone experienced the same problem? If so, can you please help me out? Thank you!
