QUASAR AVR SMD version build

[reptooyep]

Hi, i just finnished my quasar AVR SMD version.
On POWER ON, i get a message "Error PORT B, pin #0".
PB0, PB1, PB2 and PB3 are connected to the TX circuit and PB0 correspond to the T0 timing PIN of ATMEGA32.
The software is locked on this message. Could someone tells me if he had encontered this once and how did he fixed it ?
Thanks.
I join my shematic and my PCB. It's double side copper, bottom is the GND so, the red pins on the PCB are going to bottom side.

UP...
Im working for dip from ysdragon, still waiting for components to arrive

I have no coil connected. Maybe that's the reason ?
Could someone confirm that ?
If i hade the source code, it will be easyer to find out.

Hi,
I still have the message "Error PORTB, pin #0"
I can only find russian hints about that problem but my translator is crazy.
I cannot understand the hint.
Here is the post :

Наконец то залил и я прошивку.Столкнулся с проблемой программирования-
шьётся процентов на 80 и пишет ошибку. В итоге оказался битый индикатор давал такой эффект -
сняли, прошилось на ура- может кому пригодится. Первое выдало ошибку порта В, pin#0- по идее это
40 ножка проца ,ну и дальше по цепи(я в правильном направлении?).
Прошу сильно не пинать -только осваиваю эту технологию.

Maybe a russian guy around here can translate this for me ... or check at this page :

Thanks a lot

Here from my translator, nor sure if help something (text before this are data about Ru-forum member, which post this question):

Finally I "flooded" the firmware as well. Faced the problem of programming sews 80 percent and writes an error.
As a result, it turned out that the broken indicator gave such an effect, it was hurled at someone who could come in handy.
The first output of the error port B, pin # 0 on the idea of this 40 leg "basis", well, further along the chain (Am I in the right direction?).
I ask you not to kick much, just master this technology.

Hi,
I've changed the MCU (TQFP40 is a hard rhing to change with my big fingers)
The Error is still here with a continuous Bip on audio out.
For the Fuses, i put Lfuse = 3F anf Hfuse = D9
Any idea ?

Did you try it with coil connected?

Under the 62Ohm Resistor is a wire to VCC, it looks like there could be easily a short circuit.

Thanks for your answer, there was a short circuit. I've checked for short cuts before soldering componments. I should have done this after.

Now, i have a PB7 error (SCK) but the ISP connection is OK and now, i've checked for short cuts.
Strange...

Pin7 from the MCP3201 seems to be unroutet to the AVR.

[reptooyep]

Yes, the connection is good. I'll checked for power supply trouble on the MCP or maybe change the MCP

[reptooyep]

Ok, i just come back to you.
I've checked all the MCP3201 wiring with the MCU : OK
Power supply : OK

I just need a confirmation about the power supply. On the shematic, the MCP3201 and MCP633 are powered by 3.3V (VDD). Is it OK ?

[reptooyep]

I finally found out that my MCP633 was internaly short.
So, it burnsted the 5v reg.
Now, i have a ERROR PORT A, pin #1.
This pin is the ADC+ which is connected to the +5v line.
No short cut and good wiring..
This board does not want to work ...

[horbei]

hard to say, maybe a Picture of the Board could be usefull.

[reptooyep]

Hello,
After many troubles, the unit finaly power on ... for few seconds only..
I've changed the MCP633 (internal short cut) , the regulator (burnt cause of the MCP633) and the MCU a second time (the first time, it was not bad but i though it was).
The board drains 1.5A !!!, the MURS diodes become very HOT with or without coil ..

I now have to check the TX stage
