Description

This Units test first sets the PLLB to the system core clock and PLLA to clock PCK0 (used to get data from image sensor). Then UART console is configured to display information about the unit test. Next step is to initialize OV7740 cmos image sensor with a special test configuration. With this configuration the same picture will be received from sensor.
