Cant get sketches to upload on custom board...(used optiloader for bootloader)

being bored/desperate..

I took out my meter again and started testing the main Atmega chip pins (its sodered to the board) for continuity..

Im not sure if this is a 'real' way to do so?..being as it 'part' of a circuit..

but some pins.. -do- show continuity "IF" I have the probes in a certain order (black on pinA.. red on pinB).. if I flip the probes (black on pinB.... red on pinA..) it shows NO continuity...??

I think Crossroads mentioned something about that being 'normal'.... if it was a 'true' bridge.. it would show either way.

(still dont understand why ONE way out though??)

just trying to talk it out..

anybody around? or got some suggestions?

Thanks
