Baseband Testing
The MCU software enters a local mode at startup if suitable resistors are connected to the BTEMP and BSI lines. NOTE! Baseband doesn't wake up automatically when the battery voltage is connected. Power must be switched on via: 1. Pwr key or 2. BTEMP line or 3. Charger In the local mode the baseband can be controlled through MBUS or FBUS connections by a PClocals software. Baseband internal connections are tested with self tests if possible. By connecting MAD2 pin ROW5 to ground, MAD2 pins are toggled as a daisy chain, which can be used for detecting short circuits in MAD2 pins. Test pads are placed on engine pcb for service and production troubleshooting purposes in some supply voltage and signal lines.

Alignments
Within alignment those parameters are adjusted, that cannot be set accurate enough by design because of component tolerances. Due to use of 5% resistor values, the channels of the CCONT A/D converters need to be aligned in the production phase. Within battery voltage tuning the MCU software reads the A/D reading from CCONT at 4.1V and stores this reading to EEPROM memory as a reference point. Another reference point is created by assuming that while the input voltage is zero, A/D reading is also zero. Now the slope is known and A/D readings can be calibrated. Calibration is included in VBAT A/D reading task. Battery charging voltage VCHAR and current ICHAR are calibrated using one test setting. Test jig in production/service must have a connection to battery terminals. ICHAR and VCHAR are supplied fron the jig and service software calculates values, which are then stored to EEPROM.

Trouble Shooting
The following hints should facility finding the cause of the problem when the circuitry seems to be faulty. This trouble shooting instruction is divided following section. 1. Phone is totally dead 2. Flash programming doesn`t work 3. Power doesn`t stay on or the phone is jammed 4. Display information: Contact Service 5. Phone doesn`t register to the network or phone doesn`t make a call. 6. SIM card related failures ( insert SIM card or card rejected). 7. Audio fault. 8. Charging fault The first thing to do is carry out a thorough visual check of the module. Ensure in particular that: a) there are not any mechanical damages b) soldered joints are OK

Phone is totally dead
This means that the phone doesn't take current at all when the power switch is pressed or when the watchdog disable pin (X001 pin 11, J111) is grounded. Used battery voltage must be higher than 3.1 V. Otherwise the hardware of CCONT (N100) prevents totally power switchon.

Phone is totally dead Yes No J232 VBAT is 3.6 V Yes Voltage at J111 is 3.6V Yes VBB 2.8 V (R115, C107..) VXO 2.8 V (C149..) When PWR switch is pressed or WDDIS is grounded (J111) Yes See section "Power doesn't stay on" Faulty CCONT (N100) No WDDIS (J111)) is 0V, when PWR switch is pressed Yes No Check PWR switch to CCONT line: R341, R118 No Faulty CCONT (N100) Failure in VBAT line Check L103

Flash programming doesn't work
The flash programming can be done via panel connector X001 or via dedicated PCB pads. In production, the first programming is done via panel connector. After this, the panel connector is cut away, thus the programming must be done via PCB pads visible through the shield under the battery. The main difference between these is that FLASH programming voltage is produced differently. In flash programming error cases the flash prommer can give some information about a fault. The fault information messages could be: MCU doesn't boot Serial clock line failure Serial data line failure External RAM fault Algorithm file or alias ID don't find MCU flash Vpp error Original 08/98

In cases of unsuccesful flash programming there is a possibility to check short circuits between the memories and the MCU (MAD2). It is useful to do this test, when the fault information is: MCU doesn't boot, Serial clock line failure or Serial data line failure. The test procedure is following: 1. Connect testpoint J229 to ground. 2. Switch the power on. 3. If the voltage level in testpoint J225 is 2.8 V ("1"), the interface is OK. If there is a short circuit, the voltage level in testpoint J225 stays low and 32kHz square wave signal can be seen in the lines which are already tested. It must be remembered that this test can only find short circuits, not open pins. In addition upper data lines (15:8) of flash memory D220 are not included in this test.

Power doesn't stay on, or phone is jammed
If this kind of fault has come after flash programming, there are most probably open joints in ICs. The solder joints of ICs: MAD2 (D200), Flash (D220) and SRAM (D230) are to be checked at the extent possible (by microscope from the side of PCB and lightly pressing components while switching power on). Normally the power will be switched off by CCONT (N100) after 30 seconds if the watchdog of the CCONT can not be served by software. This updating can be seen with an oscilloscope at CCONTCSX (J236). In normal case there is a short pulse from "1" to "0" every 8 seconds. The power off function can be prevented by connecting WDDIS (J111) to ground.

Power doesn't stay on or phone is jammed YES CCONT watchdog is served? (J236 pulses 1 > 0 every 8 sec) NO Connect J111 (WDDIS) to GND OK VBB (C107 upper side) 2.8 V VXO (C149 upper side) 2.8 V YES Check C213, R213 YES RFC (C664) 13 MHz 800 mV min NO Check buffer V660 and VCTCXO G660 NO Master reset PURX (J227) 2.8 V YES RfClk (R213 lower side) 13 MHz sine wave clock signal: 500 mVpp min YES Open pins or faulty circuit: D200, D220, D230, N100, R215 NO Sleep clock SCLK (J228) square wave 32 kHz YES N100 faulty or overloaded PurX line NO VBAT is 3.6 V NO Check sleep clock circuitry (B101, R154..) YES N100 faulty YES Software is able to run If power is switched off after few seconds, check BSI and BTEMP lines

Flashing can give information in deciding which IC to change. Changed Flash ID for example indicates Flash failure

Display Information: Contact Service
This fault means that software is able to run and thus the watchdog of CCONT (N100) can be served. Selftest functions are run when power is switched on and software is executed from flash. If any of the selftests fails, a "contact service" text is shown on display. MCU self tests are devided to those executed while power up (start up tests) and ones that can be executed with connected PC. The tests and included items are as follows: 1. MCU ROM checksum Calculates 16 bit checksum out of Flash code and compares it to one found in Flash. Items being checked are: MAD2 <> Flash data and address lines, CE0,CE1, WE, BYTE, Vcc, GND, Flash internal functionality 2. MCU RAM interface 3. MCU RAM component 4. MCU EEPROM interface 5.

The phone doesn't register to the network or phone doesn't make a call
If the phone doesn't register to the network or the phone doesn't make a call, the reason could be either on baseband or RF. The phone can be set to wanted mode with WinTesla service software in order to find out whether the fault is in RF or in baseband (RF interface measurements). The control lines for RF are supplied both by the System Asic (inside of MAD2;D200) and the RFI (inside of Cobba; N250). MAD2 handles digital control lines (like SENA, TxP etc.) and Cobba handles analog control lines (like AFC, TxC etc.). The DSP software is constructed so that operation states of DSP (MAD2) can be seen in external flag, DSPXF (J222). After power up, DSP will signal all the completed functions by changing the state of the XF pin.

SIM card related failures
The hardware of the SIM interface from MAD2 (D200) to the SIM connector (X451) can be tested without a SIM card. When the power is switched on and the BSI line (J122) is grounded by a resistor, all the used lines (VSIM, RST, CLK, DATA) rise up to 5 V four times. Thus "Insert SIM card" faults can be found without SIM card. The fault information "Card rejected" indicates that ATR message (the first message is always sent from card to the phone) is sent from card but the message is somehow corrupted, data signal levels are wrong etc. or factory set values (stored to the EEPROM) are not correct.
