Hello,

Did somebody used the CRC Unit in the SDMA Core of the i.mx53? I actually tried, but can't access them like Burst or Per Functional Registers via stf/ldf instructions. Something like :

          stf Greg[3],CA              # Greg3 preloaded with 2

          ( Hex-Inst. => 0x6b80 )

to load the Polynomial Register (CA) did not work. Where could be the Bug?

 

some hint's will be very helpful

 

Best regards

Lars
