Hello @mbarg.1 ,thank you so much - you made my day! This got me up and running."RxDescripSection in eth.c is not RxDecripSection in xxxflash.ld - an s is missing and that appears in v1.12"Best regardsOskarP.

Hello mbarg.1,Thank you for your response. I now understand how and where the RX buffer is placed.I am aware that the IP address must be set, which is why I am using DHCP. I checked the network traffic with Wireshark.Sometimes, I receive a DHCP reque...

I found the problem: I messed up the TEX level in the Memory Protection Unit settings.I mistakenly set the TEX level for the second region instead of the first region.I’ve attached the latest code for reference. This code runs without any faults on m...

I think the srand problem and the new hard fault are two separate issues. The srand issue was caused by the linker script. I feel like the hard fault is a software bug where the &hdr->sipaddr gets placed unaligned in the microcontroller's memory.Shou...

I did some further analysis of the problem. Based on the "fault analyzer," we know that there is an attempt at an unaligned access. I have checked the address of &hdr->sipaddr, which is 0x30020036, and it is unaligned, right?If I define a new IP addr...
