I had to doublecheck this. Original board manufacturer (Starterkit) lists it as "FreeScale iMX536 (ARM Cortex-A8 1000MHz, ...". However I have verified that the board has MCIMX536AVV8C, SoC, which indeed is rated only up to 800 MHz. I'll send v2 using max 800 MHz for safety. -- With best wishes Dmitry
