SKYEYE SIMULATOR.

[kavi tha]

hi sir,
I am doing the project using skyeye simulator.I installed skyeye
1.2.5 version in ubuntu 10.0. As i am a new user i doesnt know how to
configure and execute the file.

after installing the folloeing commands are disaplayed...

ranjith@ranjith-desktop:~$ skyeye

**************************** 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.

Your elf file is little endian.

Hi kavi,

     It is pretty easy to use skyeye. All you need is skyeye configuration file for your board. This configuration file contains information you need to pass to skyeye, that tells about the target you are working on. Like the cpu, memory mapping, device configurations, etc your board has. An example of it is like this,

#skyeye config file sample
cpu: arm7tdmi

mach: at91

mem_bank: map=M, type=RW, addr=0x00000000, size=0x00004000
mem_bank: map=M, type=RW, addr=0x01000000, size=0x00400000
mem_bank: map=M, type=R, addr=0x01400000, size=0x00400000, file=./romfs.img
mem_bank: map=M, type=RW, addr=0x02000000, size=0x00400000
mem_bank: map=M, type=RW, addr=0x02400000, size=0x00008000
mem_bank: map=M, type=RW, addr=0x04000000, size=0x00400000
mem_bank: map=I, type=RW, addr=0xf0000000, size=0x10000000
net: type=rtl8019, mac=0:4:3:2:1:f, ethmod=tuntap, hostip=10.0.0.1
#net: type=rtl8019_16, ethmod=tuntap, hostip=10.0.0.1
#dbct: state=on

This config file is for At91. by the way which cpu you want to simulate. depending on that you can modify this file. Then execute this command,

skyeye -e some_elf_file -c your_config_file

some_elf_file - points to the elf binary file you want to simulate

your_config_file - points to the configuration file you have edited to fit your needs

I am planning to make a small tutorial for this on my blog. When i am finished, i will inform you.
