ST_EAR_DATA_LOOP_TEST, then Run.
Troubleshooting
Connections tested at UPP: EARDATA (pad B6), MICDATA (pad A6), and at UEM: EARDATA
(pad E2), MICDATA (pad F2). Bus interface name is AUDIODATA (1:0).
Test 9 ST SleeepX
Description
The purpose of this test is to verify the Sleep connection between the UPP and the UEM
is intact. This function tests the connection of pin_out and pin_in signals between UPP
and UEM. The result depends on functionality of UEM loopback modes and condition of
signal lines. The MCU will set UEM in looptest mode by programming via CBUS. MCU will
then read sleep clock counter registers and store value. MCU then toggles SleepX signal
High then Low and reads counters again. Expected value is 1 higher than previous count.
Explanation of Result
Pass or Fail
Manual Verification
In Phoenix, put phone in Local Mode. Next, BB Self Tests - select
ST_SLEEP_X_LOOP_TEST, then Run.
Troubleshooting
Connections tested are CBUS see Test 6, Sleepclock (J404) at UEM (D9) to UPP (H3).
SleepX (J403) at UEM (pad B11) from UPP (pad L1). Bus interface between UPP and UEM
is PUSL (2:0). Check also at UEM the OSCCAP (C234).
Test 10 ST TX / DP
Description
To verify that the Tx/Rx | lines between UPP and UEM are intact. MCU will set UEM into
Looptest mode by programming the Loop Test bit via CBUS General Control 2 register.
DSP will set Parallel-series bypass switches for both Rx and Tx in the MFI block of the
UPP by programming the TxBypass and RxBypass bits in the MFI Control Register. DSP
will write arbitrary value to TxRam of MFI, then DSP will read this data from RxRAM of
the MFI.
Explanation of Result
Pass or Fail
Manual Verification
In Phoenix, put phone in Local Mode. Next, BB Self Tests - select ST_TX_IDP_LOOP_TEST,
then Run.
