WebDec 5, 2024 · I'd suggest maybe you first get some serial logging going in your firmware and log out the raw values. Then you write a test CRC implementation on your PC and compare the sent values to the calculated expectation. Once you are getting matches (at least most of the time) move the calculation and check into the embedded device. WebJan 27, 2024 · Also, you cannot fragment IPv6 packets along the path, the way you can for IPv4, because packet fragmentation is resource intensive.
