AT8402 Diagnostics running on the Carrier
Page 2 - 21 AT8402 CLI Reference Manual
The basic modes must be combined to build a test scenario which tests the flash
memory completely. The test goal is not to test the flash device itself but the correct
connection to the CPU’s data and address lines. Data line connection is done by the
testpattern used in the ppc-flash utility, which includes all combinations of adjacent
data lines. The following testpattern is used:
{ 0xCCAAAACC,0xAAAACCAA,0xAACCAAAA,0x00000000,
0xFFFFFFFF,0x00000000,0xCCAAAACC,0xAAAACCAA }
Parameters: see above
Returns:
0 - command executed successfully
-1 - an error occured during execution
Failure impact
•
PPC-00060008 diagnostic code results from an flash read/write error. The impact
is loss of applications running on carrier host processor. This impacts at least
Ethernet functionality and command line interface.
2.7.9 PPC_SEEPROM
Test group: Diagnostics
Test case: ppc
Test procedure: PPC_SEEPROM
Test host:
Carrier
Test IC: quickturn
Test mode: normal
Diagnostic code: PPC-00060009
SEEPROM test.
Description
Read and the SEEPROM used for storing low-level board configuration e.g. SPD data
for RAM and check data for consitency.
Failure impact
•
PPC-00060009 diagnostic code results from an SEEPROM read error. The impact
is loss of applications running on carrier host processor. This impacts at least
Ethernet functionality and command line interface.
