hello guys,
i made a custom pcb using
psoc4 CY8C4245LQI-483 ,
i manufactured 4 PCBs - i am trying to program with miniprog3
in 3 of my custom circuits i get the following error :
" Unable to acquire target device..."
1 of my custom circuits seems to work flawlessly i can program it , debug , control gpio .
after double checking my schematic i saw an error , i accidently routed the VCCD pin to 3.3v instead of
connecting it to gnd (image of how i connected power is attached) ,
do you think this error is a critical design error ??? (i saw some desgins where u can connect it to 1.8v)
do you think this might be the problem ??

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".
