IXP1200 Network Processor
SA1200 Software Reset
PCI-SA1200 Reset register does not function as specified.
Three mechanisms are used to reset the IXP1200:
Problems have been observed in attempting to reset the IXP1200 via the PCI_RST# input or the
IXP1200_RESET register (SW reset).
In summary:
Hangs the system, typically after running for a period of time.
None
Fixed
Branch and Return
RTN or JUMP instructions following a Class 3 branch instruction will cause dropping of the
instruction following the return
A RTN or JUMP may not follow a branch whose branch decision is made at the P3 pipeline stage.
These branches include all Class 3 branch instructions and branches where the decision has been
postponed to the P3 stage. Please see Section 4.5.1 (Class 3 Instructions) and Section 4.5.4
(Postponed Branch Decision) of the IXP1200 Network Processor Family Hardware Reference
Manual for more information.
A program execution failure will occur.
A RTN or JUMP may not follow a P3 stage branch; program accordingly.
NoFix
PCI Parity Error Signal
Parity Error Signal not asserting.
The Parity bit in the PCI interface is not set correctly. The Parity error indication bit in the
PCI_STATUS register is correct.
Bad parity.
Use the register parity error indication in the PCI_STATUS register.
Fixed
1. RESET_IN#: No reported problems with the IXP1200 hardware reset.
2. PCI_RST#: Does not work per the specification. It does not reset the device correctly and
3. IXP1200_RESET register: Unpredictable results. Specifically customers initiating a soft reset
