I am trying to follow the 'Gmac_Ip_InternalLoopback_S32K358' example on our board. The loopback example works. Now, I am trying to send the packet out of the board through (no loopback) and I don't see any data. Looking through the example code, I see a couple of issues, could you please confirm I am mistaken or the example code is wrong. A. in src/main.c /* Payload = Frame - (DstAddr + SrcAddr + EtherType/Length + FCS) */ *((uint32 *)(TxBuffer.Data + 13U)) = 64U - (6U + 6U + 2U + 4U); question1: The above line is setting the length of the ethernet frame. Shouldn't it start at offset 12 and not 13? question2:The length is only 16bits, why is it setting 32bits? question3:Length field should have most significant byte at offset 12 and least significant byte at offset 13. The above line sets the fields in little endian order (per my understanding) and looking at the design studio watch window. B. I replaced the Destination mac address in the example code with the mac address of the partner host on the other side. Example code uses TxOptions with the following line. Gmac_Ip_TxOptionsType TxOptions = {TRUE, GMAC_CRC_AND_PAD_INSERTION, GMAC_CHECKSUM_INSERTION_DISABLE}; question4: What should I choose for the TxOptions, if I want to send the packet out of the line? question5: Any other change I need to make in the peripherals tool to get this working? thank you for your help in advance, Raj #s32k358 #s32k328 #gmac #ethernet #loopback
