Why does a misaligned memory trap happen in the NicheStack TCP/IP Stack when sending multicast message ?

Environment

    Quartus® II Subscription Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Due to a problem of NicheStack TCP/IP Stack - Nios® II Edition, a misaligned memory trap happens when a multicast message is sent and a stream of multicast messages are being received at the same time.

 

Resolution

Download two text files, pk_alloc.c and ip_write_internal.c, and update pktalloc.c and ip.c files with them to handle multicast messages correctly. This issue will be fixed in the future version of Quartus® II software.

1. pk_alloc.c
   Update <install_dir>/nios2eds/components/altera_iniche/UCOSII/src/net/pktalloc.c with pk_alloc.c

2. ip_write_internal.c
   Update <install_dir>/nios2eds/components/altera_iniche/UCOSII/src/ip/ip.c with ip_write_internal.c
