We are using LPC546xx Microcontroler
To Maximizing throughput on the processor, I would like to activate the option "CHECKSUM_BY_HARDWARE"
As proposed here:
Do you know what must be done on Ethernet Controler Part ?
I see In the User Manual:
IP checksum offload support for TCP, UDP, or ICMP payloads encapsulated over IP
So, I activated the bit 27 "IPC" of MAC_CONFIG
but as soon activated the Ethernet communication is not working any more
I think you have to set the COE bits in the MAC HW Feature0 register, I copy it here:
Pls check the IPS bit for the IP part checksum.
Hope it can help you
