Flash Programming

Flashing Tool

Flash programming is done through the VPP, FBUSTX, FBUSRX, MBUS, and BSI signals
BSI = Used to indicate to MCU that the prommer is connected and mobile terminal is in
flashing mode
MBUS = Used as clock signal for synchronizing the serial communication between the
prommer and MCU
FBUSRX = Data to D2800
FBUSTX = Data to prommer
VPP = 0v/ 1.8v/ 12v (read only/normal op. or slow programming/fast programming)

Flashing Troubleshooting

When troubleshooting flashing problems, first make sure the signals from the FPS-8 to
the D2800 processor are functioning properly before replacing any component. Once
signals between production test points and the D2200 and the D2800 processor have
been checked, verify that the interface between D2800 processor and flash is correct.
While all the signals between D2800 processor and flash are not visible, the available
signals will help identify the components that may need to be replaced.
