Michael,

I have my doubts regarding all those problems Smartbridges has encountered.
We use the same Atmel 510 H/W Reference Design and similar F/W to that of SmartBridges and all our untis perform flawless. For your information we have moved about 1000 units so far.
It amazes me how the same f/w operates so wonderfully for us and gives so much trouble to SB ?
I mean there are issues one after another and since the same people(ATMEL)that code f/w for us, code f/w for SB I would not think all those issues are f/w related. At least not only f/w related.
Last week I poped open a SB unit and looked around I know I am not an expert but my basic electronics knowledge would not allow me to place a heating element on top of the physical ethernet. Doesn't the additional heat created by the heating element raise the temp of the etherent chip ? doesn't that change the operational structure of the chip and therefore cause various missbehaviors on the ethernet side ?
I believe there are more than afew incidents and my opinion is that removing the heating element form the ethernet physical will resolve alot of those issues.
Also there are a couple of resistors on the SB data bus lay out. I doubled check the reference desing of the manufacturer (ATMEL) and there is no such a thing there.
Those are just 2 very basic observations made by the naked eye.
When ATMEL engineers code f/w or make any h/w changes the first basic assumption is that the customer (SB) followes their refference design.
I know our new units have the new ATMEL flash and we have had absolutely 0 problems with that issue.
We are located in Greece and the temp on our outdoor units goes higher than 60C. Still no heat problem, why ?
Because our OEM follows ATMEL's Reference Dessign by heart.
SB officialy "BASHED" ATMEL last week (.pdf posted the 11th) while it is strictly their fault.
I believe if they had informed ATMEL for their h/w modifications we would not be talking about it now.
For the record, this is my personal opinion and I am in no way affiliated with either one of the companies named above.
Thank you Dimitri
