 ## Description
 
-This example captures an image using the camera (e.g. OV5640) via MIPI CSI-2 Protocol and streams either to the on-board TFT display or to your PC through the COM port. Press PB0 to capture an image once the device is ready.
+This example captures an image using the camera (e.g. OV5640) via MIPI CSI-2 Protocol, saves it into external SRAM and streams to your PC through the COM port. Press PB1 to capture an image once the device is ready.
 
-Use the [utils/console.py](utils/console.py) script to grab the camera data and create a png image of the captured image. More information can be found in [utils/README.md](utils/README.md).

 ## Required Connections
 
-- Connect a USB cable between the PC and the CN2 (USB/PWR) connector.
-- Install JP41 (CSI2 CAM I2C EN)
-- Install JP40 (HW PWUP/SW PWUP)
+- Connect CSI2 camera module to J8 (CSI CAMERA)
+- Set JP38 to OFF position (DVP CAM PWR)
+- Connect a USB cable between the PC and the CN2 (USB/UART) connector.
+- Install jumper JP41 (CSI2 CAM I2C EN)
+- Install jumper JP40 (HW PWUP/SW PWUP)
+- Remove JP39 (SW CAM PWUP)
 - Remove JP16 and JP17 (I2C1 SDA/I2C1 SL)
     - This is required to ensure the I2C1 bus is pulled up properly for the CSI2 camera.  Duplicate pull-ups result in unreliable camera communication.
-- Connect the 5V power cable at (5V IN).
-- Close jumper (RX - P0.0) and (TX - P0.1) at Headers JP23 (UART 0 EN).
+- Install jumpers (RX - P0.0) and (TX - P0.1) at Header JP20 (UART 0 EN).
 - Open an terminal application on the PC and connect to the EV kit's console UART t 115200, 8-N-1.
-- Close jumper JP1 (LED1 EN).
-- Close jumper JP2 (LED2 EN).
+- Install jumper JP44 (LED0 EN).
+- Install jumper JP45 (LED1 EN).
+- Install jumper JP25 (PB1 PU).
+- Connect the 5V power cable at (5V IN).
