Add your new program to the compiled uClinux system

Add your new program-general Linux technology-Linux programming and kernel information to the compiled uClinux system. The following is a detailed description. After compiling uClinux some time ago, I never took the time to test it. Today I took skyeye out and tried it. It was normal before! The following describes the related steps in detail:
I. First install skyeye
[Root @ localhost root] # wget 192.168.5.89/skyeye.tar.tar
[Root @ localhost root] # tar jxvf skyeye.tar.tar
[Root @ localhost root] # skyeye-v1 cd
[Root @ localhost skyeye-v1] # make
In this way, skyeye is installed, which is very simple. If you have any questions, you can view README
[Root @ localhost skyeye-v1] # cat READ | less
II. Test whether uClinux can run in skyeye.
[Root @ localhost skyeye-v1] # cp./binary/skyeye/root/uClinux-dist/
[Root @ localhost skyeye-v1] # cd/root/uClinux-dist
[Root @ localhost uClinux-dist] # vi skyeye. conf
# Skyeye config file sample
Cpu: arm7tdmi
Mach: initi4510b
Mem_bank: map = M, type = RW, addr = 0x00000000, size = 0x00800000
Mem_bank: map = M, type = R, addr = 0x01000000, size = 0x00200000, file = images/romfs. img
# Mem_bank: map = M, type = R, addr = 0x01000000, size = 0x00200000
Mem_bank: map = I, type = RW, addr = 0x03ff0000, size = 0x00100000 # uart: type = jx4510b, name = uart0
# Uart: type = maid, name = uart1
# Timer: type = jx4510b, name = timer0
# Timer: type = jx4510b, name = timer1
# Net: state = off, hostip = 10.0.0.2, ethmod = tuntap, mac = b0: c4: 20: 00: 00: 00

Okay, you can run it!
3. Add your own program to the system:
[Root @ localhost uClinux-dist] # vi test. c
# Include
Int main ()
{
Printf ("this is an test program \ n ");
Printf ("written by 1jjk \ n ");
Printf ("Email: lingjiujianke@gmail.com ")
Printf ("blog: http://1jjk.cublog.cn ");
Return 0;
}
: Wq
[Root @ localhost uClinux-dist] # arm-elf-gcc-Wall-elf2flt-o test. c
[Root @ localhost uClinux-dist] # cp./test./romfs/bin/
Run the following command to generate the file system image romfs. img:
[Root @ localhost uClinux-dist] # genromfs-v-V "ROMdisk"-f./images/romfs. img-d./romfs
[Root @ localhost uClinux-dist] # make image
[Root @ localhost uClinux-dist] # make
Then try again
[Root @ localhost uClinux-dist] #./skyeye-e./linux-2.4.x/linux-c skyeye. conf
We can see the entered information:
