OBD-II STN1110 - QFN Problem
#1
Zdravo drugari, na breadboard-u imam funkcionalan uredjaj koji koristi STN1110 DIP pakovanje, na osnovu tog breadboard-a imamo dizajniran PCB, proveren xyz puta visa, i na njemu imamo STN1110 QFN pakovanje. E sad, sve sem komunikacije izmedju STN cipa i MCP2551 radi identicno i na breadboard-u i na PCB-u sto smo odradili.

PCB varijanta vraca:
"Initializing ECU"
"Check if ignition is on"

Ovo je sa Torque-a.

Direktno kad se pusti komanda preko FTDI-a na STN kaze:
BUS INIT STOPPED 
BUS INIT FB ERROR

Probacemo sutra da damo da se prelemi taj cip, da ne bude da je nesto lose zalemljeno ili da je otisao taj cip nekako (ne znam kako), ali me  zanima da li neko ima jos neku ideju sta bi mogli da probamo.

Proverili smo kao sto rekoh minimum 10-15x ceo taj deo, proverili raspored pinova DIP vs QFN i sl. i sve odgovara datasheet-u. 

Meni iskreno ponestalo ideja, a ponestaje i zivaca s ovim Smile

Svaki predlog sta bi jos moglo da se proba, kako da se uporedi i sl. dobrodosao.
