Are the
MDM_WR and
_RD signalling
present at U500
SMOC pin 100,
4?
(see page 33)
During initial radio power-up the SMOC IC performs
power on self test diagnostic to confirm that the
HW is operational.
If any of the diagnostic tests fail, an error code will
be sent in the first reply message sent to call
processor.
Check in order the following signals :
MDM_WR,SPI CLK, SPI MOSI(micro DCA problem)
MDM_RD, SPI CLK, SPI MISO( SMOC problem).
(See the example in attached on page 33)
yes
no
1) If all the above looks good, and the PCB is still not
turning on, try to resolder U702,U704,U705 with ERSA
station, if the PCB turns on, then shut down, go to
immediately in test mode to read the error code and
subcode.
2) Try to lift the EEPROM U705 and check if the PCB
(pwr up) communicate with emmibox.
If so, you read the internal info(sw,modem, speech) from
the RAM with GMSKEY.
(e.i. If the error code is 7100#02=Ext ram error,there
were some dry joint at Sram pins )
