You should have iMX53 QSB (quick start board).
My suggestion for you is: start booting up a pure linux image, just like Freescale releases for QSB. When you understand what binaries you need, and how to copy them to SDCard, you can choose which one you will use.
I haven´t worked with Meego images, but I believe you will need to modify (someway) they kernel source code.
Take this document package: https://www.freescale.com/webapp/Download?colCode=IMX53_QSB_1101_LINUXDOCS_BUNDLE&location=null&fpsp...
untar and open it. Go first on doc\mx5\i.MX53_START_Linux_BSP_UserGuide.pdf
To take source code, http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=IMX53QSB&fpsp=1&tab=Design_Tools_Tab#
Once you are able to load a pre-built image you can start working on Meego source code
