RM-305; RM-306 Baseband troubleshooting General baseband troubleshooting Important test points Introduction Measuring power suppliers is usually earlier step during troubleshooting. The following picture illustrates the test points for power suppliers. Figure 8 Test points for power suppliers Flash programming does not work Troubleshooting flow The flash programming can be done via the pads on the PWB (J2060).
PAGE 54
RM-305; RM-306 Baseband troubleshooting Phone doesn't set FBUS_TX line low Because of the use of uBGA components it is not possible to verify if there is a short circuit in control- and address lines of MCU (UPP) and memory (flash). Figure 9 Flash programming fault Page 4 –6 COMPANY CONFIDENTIAL Copyright © 2007 Nokia. All rights reserved.
PAGE 55
RM-305; RM-306 Baseband troubleshooting Phone doesn't switch on Troubleshooting flow This means that the phone does not use any current at all when the supply is connected and/or power key is pressed. It is assumed that the voltage supplied is 3.6VDC. The UEMCLite/Litti will prevent any functionality at battery/supply levels below 2.9VDC. Figure 10 Troubleshooting when the phone doesn't switch on Issue 2 COMPANY CONFIDENTIAL Copyright © 2007 Nokia. All rights reserved.
PAGE 56
RM-305; RM-306 Baseband troubleshooting Switch off Troubleshooting flow If this kind of a failure is presenting itself immediately after FLALI, it is most likely caused by ASIC's missing contact with PWB. If the MCU doesn’t service the watchdog register within the UEMCLite, the operations watchdog will run out after approximately 32 seconds. Unfortunately, the service routine can not be measured.

RM-305; RM-306 Baseband troubleshooting Figure 12 Troubleshooting when the "Contact Service" message is seen The phone does not register to the networks, or the phone can not make a call Troubleshooting flow If the phone doesn't register to the network, the fault can be in either BB or RF. Only few signals can be tested since several signals is 'buried' in one or more of the inner layers of the PWB. First of all verify that SIM LOCK is not the reason to cause phone cannot connect to network.

RM-305; RM-306 Baseband troubleshooting Figure 13 No registering or call SIM related faults Insert SIM card fault Troubleshooting flow The hardware of the SIM interface from UEMC/Litti (D2901) to the SIM connector (X2700) can be tested without a SIM card. When the power is switched on the phone first check for a 1.8V SIM card and then a 3V SIM card. The phone will try this four times, where after it will display ”Insert SIM card”.

RM-305; RM-306 System module Block diagram System module block diagram The main functionality of the BB4.1 is concentrated on two ASICs, the digital/RF ASIC is called the UPPCosto and the mixed signal ASIC, the LITTI. The program code is stored in the external FLASH memory. The simplified BB4.1 block diagram is presented below. Figure 80 Module block diagram Functional description The UPPCosto ASIC is designed to work in DCT4 cellular phone engines developed only for GSM.

RM-305; RM-306 System module LITTI LITTI is the mixed signal ASIC used in the GSMCost 4.0 engine. The main functionality is: Voltage regulation, battery charge control, audio codec, A/D conversion, various drivers, Real Time Clock (RTC), system logic, and digital interfaces. Modes of operation BB4.1 has five different functional modes: • No supply: In NO_SUPPLY mode, the phone has no supply voltage.

RM-305; RM-306 System module Figure 81 Audio block diagram The audio control is taken care of by UEMCLite, which contains the MCU and audio codec. Input and output selection, and gain control is performed inside UEMCLite. DTMF-tones and other audio tones are generated and encoded by UPP and transmitted to UEMCLite for decoding. The vibra has is driven by PWM signal, generating vibration by rotating an un-balanced mass (counter weight). The vibration signal is for example used as a silent alert call.

RM-305; RM-306 System module The GMSK output signal form the PPA is fed into a front end module (FEM). A 2dB attenuator is added between the PPA and the FEM. Digitally Controlled X-tal Oscillator The Digitally Controlled X-tal Oscillator (DCXO) provides the reference clock for the DRP2 and for the digital baseband. The only external component is the crystal (and a series capacitor). Issue 2 COMPANY CONFIDENTIAL Copyright © 2007 Nokia. All rights reserved.
