– Flash programming
In flash programming a special flash programming box and a PC is
needed. Loading is done through a test connector of PDA module using
the same serial channel as RBUS. PDA module should not use RBUS
during flash loading. First MCU goes to minimum mode (MBUS command
from PC or if MBUS is connected to EXTMIC/JCONN line in power up).
Then the flash software is loaded from PC to flash loading box. After the
loading is complete the flash loading from box to CMT can be started by
MBUS command from PC to the MCU. After that the MCU asks the test
box to start flash loading to baseband. The box supplies 12 V
programming voltage for flash and starts to send 250 bytes data blocks to
the MCU via RBUSRxD line. The baud rate is 406 kbit/s. The MCU
calculates the check sum, sends acknowledge via RBUSTxD line and
sends the data to flash. When all the data is loaded the CMT makes reset
and tells the flash loading box if the loading was succeeded or not. Only
PSL+, ASIC, SCL and MCU must be active during the loading.
