DSP
(D751992GHH)
GPIO
Camera Flash Operation
- Camera is operated by Power(2.8V), C_MCLK(24MHz-QVGA/48MHz-SXGA)
- Camera Signals divided by C_MCLK, are C_Vsync, C_Hsync, and C_PCLK
- FLASH_EN makes INT(Interrupt) by combining C_Vsync, C_Hsync, and C_PCLK
- Camera serial communication is I2C.
Check Points
- Check the power supply.
- Check the soldering of Components
- Check the FLASH_EN signals
- Check the CAMERA signals
Trouble Shooting Setup
- Enter the engineering mode.
