Enable ARP Offload on STM32H753

[ASitt]

Hi,

I try to enable the hardware ARP Offload in a STM32H753 custom board. The problem is, that it doesn't take the given IP adresse in die MACARPAR register regardless what the sequence of code is. I tryed it before and after enabling the ARPEN bit and before and after enabling the ETH Modul. The adresse where the MACARAR register is, is staying at zero. Does anybody know, how to enable the ARP offload?

Best regards,

Andreas

Hello @ASitt and @Jiahong ,

Can you share with us some details about the software configuration used for this context.

are you using LWIP FreeRtos or you are working without networking stack and Rtos ?
if you are using Lwip the Feature of ARP offload is already implemented and you can see a working example in this link (see sections with #if LWIP_ARP in ethernetif.c)
