Target reset after linux reboot

Hi everybody!

 

I got a problem. After rebooting linux system on the target,

the target "hangs". How could I get that the target makes a reset

to start u-boot or linux again?

 

Many thanks for help

 

Best regards

Frank

CLI for embedded system

Hi,
   Can anybody give me link/built in package or source code for implmenting CLI for embedded system on linux. We have tried to implement our own CLI on linux(with bash shell as base), but it is massive work since we need to support Tab feature, history feature,help etc..


thanx in advance.

If you're looking for something to emulate Cisco's IOS shell, there's an
open source project called 'clish':  

http://sourceforge.net/projects/clish/

I haven't really used this myself, so can't recommend for or against.

Dear Ben,
Thanx for giving such a wonderful reference. We are going thru document,
hope we can use the same.

hi,
    I have successfully complied and used 'clish' in host system (i686
machine)
But I need to port the same for PPC platform. Can anyone suggest me how to
do the same.

thanx in advace,

Like many other projects, I believe this one uses autoconf (I think
that's the term).  As a starting point, try:

host$ ./configure --host=ppc-linux-gnu --build=i686 CC=
${CROSS_COMPILE}gcc

/* Monitor the output of configure to make sure that everything looks
kosher.  You'll probably want to add a "--prefix=" option that tells it
where to place the end result, and there may be other options you want
too.  Read and understand the Makefile that configure creates.  Then:

host$ make

I reiterate - this is only a starting point.  This may not compile
cleanly and you will need to experiment a bit, I'm sure.  Hopefully it's
not too bad, but these projects can sometimes be a pain to get exactly
as you want.

regards,
Ben

Re: CLI for embedded system

[pjmaiya]

Dear Ben,
     I have tried following option, with host as ppc_8xx, since we are using
mpc860 processor and  also we are using montavista provided compiler
(ppc_8xx).
Our embedded target runs on montavista linux with mpc860 processor and
compiler given by monta vista(hard hat linux).

host$ ./configure --host=ppc_8xx --build=i686 CC=ppc_8xx-gcc

We are getting error ppc_8xx unkown host at some stage. When we further
investigated "clish" code we found that we need to add our new architecture
in aux_scripts/configure.sub file. We have successfully built that part. But
for some libarary we are getting error in /usr/lib/libbstd++, but we need to
change this path..only option left for us to change in "configure" file
which requires autoconf tool..Also we need to change some thing in
"configure.in". We are little bit stuck in this part..Can U help in this
regard.. Writing our make for clish is massive work!!!

thanx for help.

I really doubt you need to mess with any of these files.  Have you tried
the host parameter that I suggested (--host=ppc-linux-gnu)?  I believe
that worked for me, but it's been a while.  

Unfortunately I can't spare any time on this right now.  Have you
checked to see if there's a mailing list for the clish project?  I
imagine building this for a 32-bit PowerPC has been done before many
times over.

Ben

Have you looked at libreadline?  It will do a bunch of that stuff for you.

You'll need to provide some details.  With the information you've
provided, I'd suggest cycling power.
