76.0. "New KAV30 board problem." by SWTHOM::COSTEUX (The Present is already the Past) Thu Feb 11 1993 15:25

    I got the following customer problem:
    
    He had a KAV30 Rev A03 board where he installed Proms with his
    application built with ELN-V4.3 and KAV30-V1.1 .In this configuration all 
    works.
    Now he got a new KAV30 board (Rev B04). He moved the Proms used on the
    previous board to this new board.
    Now when he boots he gets the errors
    1) he does a hardware Reset
    2) he does a B PRB1 and gets the error ?07 SCB ERR 3
     at PC=2004792E
    
    3) he does a B PRB1 and gets an error at PC=19A55
    
    Can I get more infos. about the possible origin of this error. Board
    revision compatibility ?

76.1PC located in the BOOT ROMs.SWTHOM::VOUTERSPhilippe VOUTERS (Evry France)Thu Feb 11 1993 17:426
    Hello Jean-Pierre,
    
    With a PC = 2004792E, this would show that the problem resides in the
    BOOT ROMs containing VMB. There could be a bug in that software.
    Regards,

76.2The firmware for Rev A0x and Rev B0x is differentEICMFG::GABELSupport the arts. Kiss a synthesizist!Thu Feb 18 1993 17:008
Jean Pierre!

The firmware for KAV30 Rev.A0x (rtVAX300 rev B1) and Rev.B0x (rtVAX300 rev C1)
is different. Therefore you can't exchange EPROMs between these revisions.
In order to blast your application for a A0x board you have to use the patch
described in 54.8. For a B0x board you don't need a patch.

76.4Customer with same symptoms but different setupZYDECO::BODARealtime Products SupportThu Jun 24 1993 02:4920
Hi Jean-Pierre,

Do you know what the outcome of your customer's problem was?  Was it due
to the mixmatch of using eproms that contained the patch for the rtVAX300 rev B
boot problem (using the 96k diags + user application) on the new kav30 with
the rtVAX300 rev C?

I have a customer with the same symptom of receiving the halt message
			%07 SCB ERR3

However, he claims he reblasted his eproms using the patch for a kav30 with
the rtVAX300 rev B.  He is confirming his halt PC.   Reportedly
he added new code to the application and has simply reblasted using the
96k diags and his patched system image.  He also is suspecting some h/w problems.

So I'm just looking for additional causes for this halt message as well.

Thanks,

Alan
