ERROR #
<15:0>
FRU(s) Component Failure Description
Low memory mailbox access test 56
NO Error/FRU callouts for this CPU/MEM
test. (supported in Powerup mode ONLY)
Memory thrashing test 57
NO Error/FRU callouts for this CPU/MEM
test. (supported in Powerup mode ONLY)
Console flash ROM checksum and unload test
0001 PBP.PCIx FLSH0 No STDIO was found in the earlier Local IO
Config Test, so no valid STDIO info was
passed down from the PSM. Note: In
powerup, should not see this error since SCM
will NOT run Test 58 if NO Valid STD I/O was
found.
0002 PBP.PCIx FLSH0 Checksum failure on PAL/Console image
unloading from offset = 28000. STDIO Flash
ROM access failure likely.
0003 PBP.PCIx FLSH0 Checksum failure on the PAL/Console image
sitting in memory (after the unload)
58
Parameters for Error #0001
P1: STD IO info in bits <7:0>. If <7>=1, the STDIO info Valid. Else not valid. <5:4> = hose#
where STDIO is located. <2:0> = HARD QBB# where the STDIO resides.
P2: CPU Number in bits <1:0> passed by the PSM. Primary CPU if bit<7> = 1
P3: Start of PCI Memory Space Address of Flash EEPROM (where Console resides)
P4: Soft QBB ID of QBB where STDIO is located (based on P1 above)
Parameters for Error #0002 and #0003
P1: Received Checksum (calculated while unloading PAL/Console from Flash)
P2: Expected Checksum (read from last LW in PAL/Console Flash image in Flash ROM)
P3: Address in STDIO Flash where Expected Checksum was read from
P4: Address in Bcache where the last LW of the PAL/Console Flash image was written to
59 ‘Alternate’ Console Unload -- Same Error/FRU callouts as Test 58
