Tom, The .sdcard file produced by the bitbake process has the partition information baked in already so you want to write it to the raw sd card device.
On my particular system I write the files to /dev/sdX not to /dev/sdX1. The exact letter your sd card shows up as will depend on what other devices are present in your system. On my Ubuntu dev system when I insert the sd card the system automounts the existing partitions so I always need to umount the partitions before I can write to the raw device. So the whole process looks like insert sd card sudo umount /dev/sdX1 sudo umount /dev/sdX2 sudo dd if=core-image-minimal-boardname.sdcard of=/dev/sdX bs=4M On Thu, May 22, 2014 at 11:33 AM, tom campbell <[email protected]>wrote: > List: > > I've built the Freescale imx6 beta successfully from: > fsl-yocto-3.10.17-1.0.0-beta.tar.gz > L3.10.17_1.0.0_beta_131223_images_MX6.tar.gz > cd fsl-community-bsp-platform &&\ > MACHINE=imx6slevk source setup-environment build-evk &&\ > bitbake core-image-minimal > > > I have a question about sd card partitioning.
