In version v1_00_b of the xps_ll_temac, TX CSUM off loading is broken, and the Checksum Offload example code for the XPS LL Temac core, "xlltemac_example_intr_sgdma.c," is commented out so this test does not run.
When the test code for Checksum Offload is uncommented and run, the following error occurs:
"Temac: Rx packet rejected"
The corrected x_ll_if.vhdl file that fixes this issue is available at:
Unzip and put the tx_ll_if.vhdl file in the local "pcore" directory of your current project.
The issue will be fixed in xps_ll_temac_v1_01_a of the xps_ll_temac in EDK 10.1 and will be available at:
