Introduction for use
(1)Install the driver under Windows
Find zadig-2.5.exe in the tool software folder and open it.
(4)Brush tool SUNXI-FEL
This tool is when the Allwinner SoC fails to boot in all Flash,the chip automatically enters the FEL Flashing state and communicates through USB.
This part will use sunxi-fel.exe in the compressed package. Do not insert the TF card,press and hold the BOOT button and then plug in the USB cable;or insert the USB first,press the RST button while holding the BOOT button,you can actively enter the USB Flashing mode,and the computer detects a new USB Flashing device.
When using sunxi-fel,you must use the command line.For example,you can install a git tool(https://git-scm.com/downloads)instead of the terminal that comes with windows. A working FEL device,we can test ir with the command:
(5)Brush tool DFU-UTIL
️This part will use dfu-util.exe in the tools folder.
️️️①Put the module in FEL mode.
②Run the from-fel-to-dfu.bat script,double-click to run.Or run the commands in the script on the Windows command line.
③At this point,the module will print some logs.When you see these,it indicates that the module is in DFU mode.
④Prepare the NAND image, and then use the following command to flash the machine in the Windows command line.
(It is recommended that professionals can directly test)
Use a TYPE-C cable to connect to the TTL interface, open putty.exe; wait for the board to start and enter root without a password.
Set image format:
media-ctl --set-v4l2 '"ov2640 0-0030":0[fmt:YUYV8_2X8/640x480]'
fswebcam -d /dev/video0 --no-banner -r 640x480 -S 10 1.jpg
After completion, you can connect another TYPE-C cable or unplug the cable on the TTL interface and then connect it to the OTG interface, wait for a device to appear, and then open it to see photos in 1.jpg format
[fswebcam -d /devideo0 --no-banner -r 640x480 -S 10 1.jpg]
Modify the command to:tinymix set serial number content
For example:# tinymix set 2 1 Modify the value of item number 2 to on,on
# tinymix set 1 63 Modify the value of item number 1 to 63
# tinymix set 13 1 Modify the value of item number 13 to on
LCPITester_ Instructions for using F1C software (it is recommended that beginners can use the F1C200S specialized testing software developed by Elsa Technology)
The following is the test method using Putty general software. Customers who want to speed up the test can use the F1C200S special test software developed by Airsay Technology, as shown in the figure below:
Way for use:
1.Connect the peripherals that need to be tested (such as LCD),and connect the USB port of the computer to the TTL Type-C interface on the development board through a USB cable.
2. Select the correct port number,baud rate 115200,click "Connect",and the window will print out a lot of debugging information.After the system starts up,click "Disconnect".Then click "Connect",when the following information appears,it means that the login to the Linux system is successful,and the function test can be carried out.
Remarks:The software only supports ports within COM9.If the port number recognized by the computer exceeds COM9,please modify the port number in the Windows Device Manager.
2.At this time,the software will ask whether the test is successful,and if you click "Yes", the LCD will display green, Otherwise, it will display red. The test method for the rest of the functions is similar to this
Source code compilation
1. Virtual machine installation
LC provides customers with virtual machines that have built various compilation environments. You can directly install the virtual machine for compilation.
Proceed as follows:
①Download and unzip the Ubuntu_16.04_X64_ES_LCPI.7z virtual machine file
②Open the VMware Workstation software, click "Open Virtual Machine" and locate the folder you just extracted.
Ubuntu_16.04_X64.vmx file in Ubuntu_16.04_X64_ES_LCPI-200S
Wait about 1 hour (depending on the computer configuration) to complete the file packaging. The image file output path is:
