How do you use the LWIP hardware checksum

calvinday — Wed, 25 May 2016 00:51:36 GMT

I am using the K66 and would like to use the ENET hardware checksum.

I have set:

ENET_TFWR |= ENET_TFWR_STRFWD(1);

ENET_TACC |= ENET_TACC_IPCHK(1) | ENET_TACC_PROCHK(1);

and defined

CHECKSUM_BY_HARDWARE

but the checksum does not work. Is there something else I should do?

Hi,

You also need to enable the ENET_TACC[SHIFT16] & ENET_RACC[SHIFT16] bits.

Wish it helps.
