Hi tom

firmware may fail to load due to kernel version incompatibility,

in general one can try to debug it using AN4553 Using Open Source Debugging

Tools for Linux on i.MX Processors
http://www.nxp.com/assets/documents/data/en/application-notes/AN4553.pdf

Also every device may require different firmware version, one can try to obtain updated

firmware for that particular device from renesas.

Best regards
igor
