Our EVK is properly booting a fresh rebuild of imx28_ivt_linux.sb and imx28_ivt_uboot.sb.  On our prototype, we see the bootlets execute properly but end up with a crash just before u-boot or Linux begin execution.  Our output is below.

The system reboots after the Undefined Ins output.

 

Has anyone ever seen this error?  We have only found one other reference to this error, and it was due to a memory issue.  We defined MEMORY_TEST in the bootlet as suggested by that thread, but all appears to be well.  Neither the uboot or linux images will boot on our board, but they function fine on the EVK.  We cannot even find out what code is spitting out the error. 

 

Any help is appreciated!
