Cool, I got these magic values from a CAN hardware expert. > I wish Can-core could calculate like above. Me too! I also got some indication on how to improve our algorithm in case the bit-rate does not match. Hope to find some time soon to work on this issue. >>> seg1/seg2/sjw/prop_seg must be more than 1 ? > BTW, according to EG20T PCH data sheet, > CAN bit-timing parameters(BRP, Prop_Seg, Phase_Seg1, Phase_Seg2, SJW) must > not be set 0. OK, then please provide a patch setting tseg1_min to 2.
