Re: Digest Number 4558

I don't think Digi cares about Rabbit sales. Since buying Rabbit/Z-World, they havedone nothing with the product line. No new modules, no compiler updates, no bug fixes,and very little response to tech support queries. I think they were just getting rid of thecompetition when they bought the product line.

    Thanks both.I am comforted that it is probably not a problem of our making.It is a shame about the brick wall that Digi have built. It is bound to lose them sales.  They have certainly lost our custom. We shall never use Rabbit modules again in new designs.There are better ones around anyway. We have used the Netburner on some other products and, after around 500 units there have been no problems like this. The Netburner MOD5570 and MOD55415 are true 32 bit devices with flat addressing without messing with pages. Ken

  Ken,
Years ago we had a similar problem where the module would boot up with incorrect baud rates. As Tom suggested, we modified our initialization code to set the clock divisors an not rely on the Bios to do it. That solved the problem for us.

Has anyone seen a problem on the RCM3000 core 
modules where they fail to initialise properly at power-up?
We are seeing it on RCM3110 and RCM3200 at lower 
temperatures, around 15 to 20 Celsius.
The symptoms are that the timers A and B do not 
produce the required frequency divisions. Baud rates are wrong.
The symptoms are always cured by 
taking  /reset_in low manually. That sort of eliminates our 
code.
 
Despite the fact that we are buying large 
quantities of Rabbit modules from Digi they are being particularly un-helpful 
about this problem. I am afraid that they appear much less helpful than the old 
Rabbit people.
They have given advice such as "connect an external 
reset timer to /reset_in "!!. 
After one department suggested  that we 
send a couple of troublesome modules back for them to investigate another 
department refused to take them because "they are out of warranty" .
 
We have spent many hours testing and trying to 
eliminate any source of the problem that might be in our application and can 
find none. We are convinced that it is a design or manufacturing problem in the 
product.
 
Due to Digi's hard-line and unwillingness to 
support their product we have decided to eliminate Rabbit modules or 
any other Digi product from any short list of components for any new 
projects.

  Ken, 

I also ran into this. We had the wrong cap on the crystal and it did not start up at the right frequency but eventually locked in. Putting the correct cap on solved the problem. Since then I used an oscillator, now I don’t have to worry about purchasing buying a different manufacturers crystal that wants 22pf instead of 18pf.
