Maybe the overhead in the case of short transactions frightened designers. Nevertheless, I have an ADM1032 evaluation board, and the ADM1032 is supposed to support PEC. I tried i2cdump in "bp" mode and it failed, but I guess this isn't surprising with Hideki reporting read_byte and read_byte_data w/PEC being broken. At least this should help me test any fix (or rewrite) I may do on software PEC support. -- Jean Delvare
