Baseband Description and Troubleshooting

Camera

When you activate the view finder to take a picture, the D2800 turns the camera on by
turning on GENIO(47) PDN and GENIO(24) 9.6MHz. After the camera initializes, the
D2800 sends control commands through the I2C (GENIO (25 and 26) interface. The
camera takes a picture and sends the raw data back to a separate hardware accelerator
(HWA) device to run the algorithms in the hardware. The HWA performs all tasks to
deliver stills and the viewfinder to the baseband with no further processing required
from the D2800. The D2800 takes the image processed data from the HWA and stores
the image in the Flash Memory or MiniSD.

Camera Troubleshooting

Check the following:
• Power Supply Enable D800_GPIO (47)
• Power Supply V2.8, VDIG and V1.2
• Camera Enable GenIO(27) is High (PDN)
• Camera Clk GenIO(24) (9.6Mhz)
• Control line I2C on GenIO 25 and 26
• CCP data/clk lines from sensor to HWA, then to the D2800
• Camera socket
• D2800 for solder problems; replace if necessary
