Does anyone know how it might be possible that the DM816x EVM can suddenly stop booting from the unmodified TI issued SD card with the Linux Kernel 2.6.37 Demo image? No modifications were made to either the SD card or the EVM board. User space software video development (no Linux kernel development) was being done on the CortexM3 as well as on iCont1 and iCont2 through an XDS560v2 emulator. The error message that uBoot dumps is the following:
