Supported cameras
AI7688H has installed Linux UVC (USB Video Class) drivers to provide USB webcam suppport. Webcams follow the UVC standard can be supported on AI7688H. The real capabilities and supported resolution depend on the current UVC driver implementation.
Step-by-step
we use mjpg-streamer as the streaming application and it's already installed in the system firmware by default. For the webcam, Logitech C310 is used in this example.
- Step 1: plug the webcam into the USB host port on AI7688H
- Step 2: type the following command in the system console
- Step 3: connect the PC to the same local network as AI7688H
- Step 4: open a brower and check the video

3.7 Change bootloader Console

If you want to use another UART port as the bootloader console, you need to modify the

bootloader.

# Get bootloader source code

# modify the file board/rt2880/serial.h

* UART registers

#if defined (MT7621_FPGA_BOARD) || defined (MT7621_ASIC_BOARD) || defined

(MT7628_FPGA_BOARD) || defined (MT7628_ASIC_BOARD)

#define RT2880_UART1 0x0C00 /* UART Lite */

#define RT2880_UART2 0x0D00 /* UART Lite */

#define RT2880_UART3 0x0E00 /* UART Lite */

//#define CFG_RT2880_CONSOLE RT2880_UART1

#define CFG_RT2880_CONSOLE RT2880_UART3

#else

#define RT2880_UART1 0x0500

#define RT2880_UART2 0x0C00 /* UART Lite */

#define CFG_RT2880_CONSOLE RT2880_UART2

#endif

and modify the CFG_RT2880_CONSOLE configuration.

Note that in bootloader code, RT2880_UART1 refers to UART0(UART_TXD0/UART_TXR0)

and so on. So modify the following modification:

Change this:

//#define CFG_RT2880_CONSOLE RT2880_UART1

#define CFG_RT2880_CONSOLE RT2880_UART3

to this:

#define CFG_RT2880_CONSOLE RT2880_UART1

//#define CFG_RT2880_CONSOLE RT2880_UART3

This changes the bootloader console from UART2 to UART0.

if you also want to change the baudrate, please modify the file include/configs/rt2880.h
