Hello, I got the expected value from WireShark. WireShark calculate the CRC as Frame Check Sequence. We executed Wireshark on Linux. (Wireshark says FCS is incorrect, but it is in spec. https://www.wireshark.org/faq.html#q10.1) We calculated CRC of the data byte sequence (real ethernet packet) by three programs. [A] " controlSUITE \libs\dsp\VCU\v2_10_00_00\examples\crc\2837x_vcu2_crc_32 " on TI Reference Board [B] The C program calcrc.c from http://kozos.jp/fpga/spartan3a_ether_tx.html (Sorry, Japanese Page) on Linux [C] The C program from https://blog.goo.ne.jp/masaki_goo_2006/e/69c68a18c872338e8c2751d662706f46 (Sorry , Japanese Page) on Linux The CRC value is [A] = [C] and [B] = Wireshark. That's why I think it is an algorithm difference. Kento
