IMX8M IP accelerator functions

Hello,

 

I try to activate the IP accelerator functions to compute the checksum of the IP header but on the reception this field is still equal to 0.

I set the register TACC to 0x8 (IPCHK field set) and I set the field IINS of the enhanced buffer descriptor.

The field Checksum of the IP header is initialize to 0.

 

Did I miss something to use this functionality? 

 

Best regards

Alexandre
