FreeRtosIP - Suggest You Add Protocol Checksum config settingPosted by joehinkle on July 10, 2016 The ENET in the Kinetis family of micros have the capability to perform IP, and protocol checksum generation (UDP, TCP, ICMP). I suggest you consider adding a config setting that would set the protocol checksum to ZERO -- have the harware perform the calculation -- it makes a measurable change in performance. I've implemented hard code changes in my version of the stack but would love to have future releases of FreeRtosIP include this so I can upgrade easier. Thanks for lostening. Joe FreeRtosIP - Suggest You Add Protocol Checksum config settingPosted by rtel on July 10, 2016 Are you talking about FreeRTOS+TCP? If so, I thought that option existed already - maybe its not in the currently release version. FreeRtosIP - Suggest You Add Protocol Checksum config settingPosted by joehinkle on July 10, 2016 Yes. I was debugging a reply to an external PING and found the checksum was being set in the ping reply. I did a solution search and found three other places where the checksum was being set that were not surrounded by a config setting. IP checksum is configured. I was just suggesting a config for the protocol related checksums also. Joe
