Install skyeye in Ubuntu

I used to learn the embedded qt development and porting process on the development board. After returning the lab to the school, you need to build a simulation environment yourself. In QMemu and skyeye, I chose skyeye, which is easy to configure and can simulate multiple arm systems, such as uCLinux, Linux, uC/OS-II and other embedded operating systems. 1. download and install the skyeye dependency package

In QMemu and skyeye, I chose skyeye, which is easy to configure and can simulate multiple arm systems, such as uCLinux, Linux, uC/OS-II and other embedded operating systems.
1. download and install the skyeye dependency package

Run the following command:

Sudo apt-get install libgtk2.0-dev pkg-config libatk1.0-dev libpango1.0-dev libfreetype6-dev libglib2.0-dev libx11-dev binutils-dev libncurses5-dev libxpm-dev

2. install skyeye

You can use either of the following methods.

(1) use commands

Sudo apt-get install skyey

Run skeye after installation, as shown below:

* *************************** WARNING *********** ***********************
If you want to run ELF image, you should use-e option to indicate
Your elf-format image filename. Or you only want to run binary image,
You need to set the filename of the image and its entry in skyeye. conf.
**************************************** *******************************

This interface indicates that the installation is successful.

(2) Download and compile the latest installation package

Step 1: Go to the official skyeye website.

Step 1: decompress the original file, tar-xvf skyeye-1.3.4_rc1.tar.gz.

Step 2: Enter the decompressed file.

Step 3: Install.

Sudo./configure
Sudo make lib
Sudo make
Sudo make install
Sudo make install_lib

Step 4: installation problems and solutions.

Error 1: various errors occurred during the installation process mainly because some software packages are not installed. I will list the additional required software packages:
Termcap library file: execute sudo apt-get install libncurses5-dev installation in the terminal.
"XCreatePixmapFromData" Error: sudo aptitude install libxpm-dev.
"Makeinfo" Error: sudo apt-get install texinfo.
Before installing skyeye, you can install the above three libraries in advance to reduce inexplicable errors.

Error 2,

Utils/uart_console/uart_console.c: 58: Error: expected identifier or '('before numeric constant
Utils/uart_console/uart_console.c: 59: Error: expected identifier or '('before numeric constant
Utils/uart_console/uart_console.c: 62: Error: expected identifier or '('before numeric constant
Utils/uart_console/uart_console.c: 63: Error: expected identifier or '('before numeric constant

Error: expected identifier or '('before numeric constant
It is because the definitions of POLLRDNORM have been defined in other header files.
Solution: comment 58 to 63 lines
// Const uint32_t POLLRDNORM = 0x040;
// Const uint32_t POLLRDBAND = 0x080;
// Const uint32_t POLLPRI = 0x002;
// Const uint32_t POLLOUT = 0x004;
// Const uint32_t POLLWRNORM = 0x100;
// Const uint32_t POLLWRBAND = 0x200;

3. installation successful test

Enter skyeye on the terminal, and the following error occurs:

Sudo cd/usr/bin
Sudo ln-s/opt/skyeye/bin/skyeye (skyeye points to/opt/skyeye/bin/skyeye)

After installation, the LCD and touch screen may not exist. you need to modify skyeye. conf.

LCD: state = on
Uart: mod = term

Test testsuit

Unzip testsuit and go to the skyeye-testsuite-1.3.0_rc1/uClinux/at91/uclinux_cs8900a

Enter sudo skyeye-e linux

Test complete

4. run the SkyEye command line application

There is a test program "arm_hello" in the/opt/skyeye/testsuite/directory.

1). go to/opt/skyeye/testsuite /;

2) enter the sudo skyeye-e arm_hello command to go to the skyeye command line interface;

3) run the "start" command to load the configuration and initialize the target machine. an xterm window is displayed on the host. the window title is "uart_instance ";

4). then we can enter the "run" command to start the helloworld test case;

5) run the "stop" command to stop the target board;

6) enter "info regitsters" to view the value of the current register;

7) enter the "disassemble" command to decompile 0x00004c, for example, "disassemble 0x00004c ";

7. The skyeye terminal uses the term (Ubuntu is xterm), which is particularly difficult to display. we can modify the display features of xterm.

Modify ~ /. Xresources (create one if you don't have one)

Example

Xterm * locale: true

Xterm. utf8: true

Xterm * utf8Title: true

Xterm * faceName: Monaco: pixelsize = 14

Xterm * faceNameDoublesize: WenQuanYi Zen Hei: pixelsize = 15

Run the following command:

Xrdb-load ~ /. Xresources

Restart or import the settings.

5. start skyeye

Enter the following command on the terminal:

Sudo skyeye-e linux

Build a cross-compilation environment in ubuntu

After the hardware simulation environment is installed, you need to install the cross-compilation tool. I downloaded the file at http://opensrc.sec.samsung.com/download.html. Fast network speed.

After the download is complete, you must first modify the content of the file at once, otherwise the compilation fails:

Vim, arm-uclinux-tools-base-gcc3.4.0-20040713.sh,

Tail + $ {SKIP }$ {SCRIPT} | bunzip2 | tar xvf-
To:
Tail-n + $ {SKIP }$ {SCRIPT} | bunzip2 | tar xvf-

Then run:

Sudo sh./arm-uclinux-tools-base-gcc3.4.0-20040713.sh

Note:

The default installation path is/root/bin/arm-uclinux-tool. the system cannot directly find the path, and even if the environment variable is added to/etc/environment, this command can be searched only when it is converted to the root identity.

Therefore, after the installation is complete, you need to copy it from the/root/bin directory as root to the target directory. I copied it to/opt, that is: /opt/arm-uclinux-tool, and then add ":/opt/arm-uclinux-tool/bin" after the PATH environment variable in vim/etc/environment ", restart the computer. after the computer is turned on, enter arm-elf (press the tab key). it will be automatically supplemented by arm-elf-g ++ through bash.
