Does the SPI Flash must be removed to use the ISI interface?
 
Question
I find that the pinout PDF of MYD-JA5D4X Development Board says that the SPI Flash is connected to some of the ISI Camera interface pins. Does this mean that the SPI Flash must be removed to use the ISI interface?
Answer
Our CPU module SPI flash is using PC0, PC1 and PC3 pins which are corresponding to the ISI signal lines D8, D9, D10 and D11. If the camera using 8 data lines, there is no conflict; If using 12 data lines, the ISI signal lines are needed to be reused and SPI code will be disabled, the CPU module hardware needs to disconnect the SPI flash jumper.
