Flash Programming (1)
Flash programming doesn’t work
EEPROM (D240) pin 8 (VBB) 2.8 V
J522 (VXO) 2.8 V
NO
See section: Phone is totally dead
YES
J227 master reset (Purx) = ”1” (2.8 V)
NO J228 sleep clock(SCLK)
square wave 32 kHz
NO
YES
Faulty circuit N100
or over loaded PurX line
check sleep
clock circuitry
(B100, R154...)
YES
MAD2 (D200) pin 93: 13 MHz sine wave
clock signal: 500 mVpp min.
YES
NO
J506 (RFC) 13 MHz
800 mV min
YES
check C213, R213
NO
check buffer V705 and
VCXO G600
Check that following lines are correct:
YES
If the fault information from the prommer is:
b) serial data line failure
a) MCU doesn’t boot
c) serial clock line failure
connect:
FCLK (MBUS) line: X001 pin 2 –> D200 pin 112
FTX (fbus_tx) line: X001 pin 1 –> D200 pin 104
FRX (fbus_rx) line: X001 pin 2 –> D200 pin 109
check also pullup and pulldown resistors: R203, R201, R215
OK
WDDIS line: X001 pin 11 –> N100 pin 29
GND : X001 pin 7 –> GND
connect watchdog disable (WDDIS) line (X001 pin 11) to the ground
check
OK
OK
Enable the selftest function of D200 by connecting
shortcircuit between testpoints J229 and J230
Connect an oscilloscope to testpoint J225 and switch
power on
Voltage level rises to ”1” after power on at testpoint J225
NO
YES
There is a shortcircuit
somewhere in memory control
lines or MCU address lines or
MCU lower (7:0) data lines
There could be open pins in circuits D200 (D211, D240)
If not, the PCB or D200 (D211, D240) is faulty
