hi bob ,
i saw this document , i know i have a mistake this pin(VCCD) should
be connected to gnd via CAP or to 1.8v via CAP and i connected
it to 3.3V.
the question is do you think this error is a critical error?
why is 1 of my custom PCBs is working just fine?
can is i disconnect this pin?
It is a similar situation: You find a sign-post "Do not step on the grass". Your experience says that stepping ongrass does not harm. But you may get caught by an authority.
When 1 board out of 4 does not work, I (personally) would consider the situation as "critical".
