Not able run commands on console
 
Hi All,

I am able to port and run Embedded linux on my ARM,EP9307 board from cirrus logic.But the problem is that,i am getting the # prompt but i am not able to run any commands on to that.I have properly configured and cross compiled busysbox for that board.Please support me in solving this issue.

Thanks and Regards,
Ravi Chobey

By "not run" do you mean...

* You type away and nothing appears?
* You type a command and you get something like "Bad command"? (Umm. Exactly what do you get?)
* You type a command and nothing happens?
* Does a fierce dog prevent you from approaching the keyboard, hence you can't run any commands? :-)

How are you connecting to the device? Serial port? USB? Ethernet?

Busy box has a built in "help" command.

What happens when you type help?

What happens when you type ls?

What happens when you type
echo $PATH

hi cyent,

Thx for ur reply,

* You type away and nothing appears?
yes when tried to type command nothing appears on my serial console. Even command I am typing is not getting echoed on terminal
i.e "system is hanged state"

I am connecting my device through serial port "/dev/ttyAM"


Regards,
Ravi

So all this is taking place on an arm based board?

Exactly what is unable to run arm code? Are you trying to run arm code on a pc? We cannot see what you are doing - you have to tell us.

I have properly configured and cross compiled busysbox for that board.Please support me in solving this issue.[/QUOTE]

If you know busybox is compiled right, has it all it's libs?

ldd /path/to/busybox

cyent 11-29-2009 02:06 PM
Things to double check (triple check)
* Baud rate / stop bits of embedded device and PC.
* Swap out cable with another. Sad to say, in my experience bad connections are often a problem.
* Does anything appear before the # or just the #? (If something meaningful does appear then it probably isn't baud rate. :0)
* Is that the only serial port on the device?
* Give as much info as possible on versions and config settings you have. You are giving us extremely little to go on here. The probability we solve it with this much info is near zero.
* Swap out arm board with another.
* Swap out arm board with another PC / port on the same PC. Verify comms.

Hi Cyent,

Thanks for your reply.
I am able to boot linux on my ARM9 board.I am able to type some commands on that board.But after that the system is going into hang state.When i am rebooting the system again,it is giving me CRC error,base address related errors and Freeing init:128 k related error.
I want to know whether it is a software or Firmware related error.

Regards,
Ravi

cyent 12-03-2009 03:10 PM
Copy and paste the full/exact error messages into your replies.

Does it hang after a specific class of commands (eg. accessing a disk device, or network, or particular drive)?

Don't be shy...

The faster you poke at the thing and the more info you give us the better chance we have of helping you.

How are you accessing it? Via serial port? Ethernet?

Can you ping it even after the hang?

What's the output of "dmesg"?

ravi_chobey 12-03-2009 09:12 PM
Dear cyent,

i am not able to ping after hang condition.

i am able to run one or two commands like "ls" and "cd",after that system is coming under hang condition.Please go through the logs:

Hmm. I don't really know...

Items in that log output I'd worry about are...

RAMDISK: wrong blocksize 8096, reverting to defaults
RAMDISK driver initialized: 2 RAM disks of 32768K size 1024 blocksize

These look as though the partition / flash layout isn't aligning with flash block boundaries. May be a problem.

mtd: partition "FIS directory" doesn't end on an erase block -- force read-only
0x00fff000-0x01000000 : "RedBoot config"
mtd: partition "RedBoot config" doesn't start on an erase block boundary -- force read-only

Seems a bit strange..

In the category of getting desperate and clutching at straws...

If you have another one of these devices lying around... can you install the same set up on it and get it working?

Put a volt meter on your power supply, is it correct?

What patterns do you notice?

Does it take the same time to die each time? Try five times and measure number of seconds to death.
Or same number of commands? Or same number of characters? Or same set of commands?

Dear Cyent,

I am having two boards,but on one board i am getting "system halted" error.The second board on which i am working currently, is not able to work properly,i am not able to enter,when i am executing "ls" command,it is executing,but when i am trying to execute some more work,it is coming under hang condition.I don't know whether the system is hanged or keyboard is hanged.I am forwarding the log:

Notes....

* The logs are the same.(Diff'ed them)

* Since hardware different but same problem, probably not a hardware fault. (Unless using a common power supply perhaps)

* Ram, start and length, as detected by redboot is weird.
RAM: 0x00000000-0x04000000, [0x000433a0-0x03fdd000] available

Where are those numbers coming from? Are they correct?

* This log message worries me...
RAMDISK: wrong blocksize 8096, reverting to defaults
where is that block size coming from? Can you fix it?

Dear Cyent,

Finally i was able to run linux on my board.The changes which i have done was,i have removed drivers of USB,Networking(ethernet port is not there) and watchdog timer.Also i have partition related settings in MTD drivers for -1 to 0.

Thanks for your support Cyent.

Regards,
Ravi Chobey

Progress, but you haven't in any way solved the problem.

Now put things back one by one and find out what broke it.

And then take them all out again and put them back in one by one in a different order to prove whether it was one of those things that broke it, or you ran over some boundary or you had some noxious interaction between those subsystems.
