I have this working.  I created a imx-bootlets.in (added to the boot loaders section) and imx-bootlets.make file and Ptxdist builds the SB files just fine.  I just need to figure out how to add a dependency on the kernel build.

Hi,

I have a Ptxdist (2011.07.0) build for the MX53 and I and looking at also building for the mx28.  I see under the platformconfig bootloaders there is a mxs-utils option for the mx28/23.  That all built and now I see the elftosb host binary which I know is used in the FSL SDK.  Do I need to build the mx28 bootlets out of Ptxdist and then us the elftosb, much like the SDK, to create the bootable SB file?  I'm lost on this last step of creating the bootlets like the mx28 SDK so I can use Ptxdist for the mx28.  Any pointers is much appreciated.

Thanks,
Jeff
