I am using a Variscite VAR-SOM-AM33x Development Kit. The stock Arago Linux booting out of NAND or the pre-packaged SD card works just fine. I have downloaded the distribution from the Variscite FTP (SDK-06.00.00.00.VAR.R13) and have been able to build the kernel under Ubuntu. I followed there VAR-SOM-AM33 LSP Users Guide:
http://www.variwiki.com/index.php?title=VAR-SOM-AM33_Arago_GS
Looking at the pre-packaged SD card (4GB), there seems to be 5 partitions: 71MB Healthy(Active, Primary Partition), 8MB Unallocated, 706 MB Healthy (Primary Partition), 2.93GB Healthy (Primary Partition), and 58MB Unallocated.
Another thing, if I create a single partition FAT32 SD, the build MLO works, but not the u-boot.img, but if I copy the u-boot.img from the pre-packaged SD, that combination works.
Once I get the built uImage loaded and running, the kernel that I build panics as follows:

Anyone working with this system? Could use some pointers/information how to get it going and develop a few applications to test.
Thanks,
