Linux booting halts

Gian — Wed, 05 Jul 2006 15:11:18 GMT

hi to all!
So, i have a 547x/548x lite evaluation board with MCF5484 processor.
i build a linux image with LTIB and succesfully downloaded and executed colilo.
i have also downloaded my linux kernel image called "vmlinux.bin". Following the freescale's linux target image user's guide (specific for MCF54x5 and MCF54x4) after the download, it says to type "config save" and "g 2000" commands...
the commands output is shown below:

Linux booting halts 2 (a bit more)

Gian — Fri, 07 Jul 2006 16:51:51 GMT

Hi to all!
Thanks to Coray for the suggestion and for his linux.bin image:
I tried it and works for itself, but now i have problems with my server PC, not with linux image. Infact as shown in the output below, target linux cannot mount /tftpboot/ltib because the server returned error (-13 it says).
The nfs server was configurated and restarted as sad in the user's guide.
I looked in my /dev directory but i didn't find any nfs device, so i thought that it could be the problem. Isn't it?
If so, how could i solve it?

As you request me by mail i show you also the colilo "?" output
now it works correctly and my beginning problem was a bit stupid: i didn't know that colilo works by default at 19200 baud rate, while my coldfire and minicom was setted for 115200!
So I seen garbage when i tried to run colilo!!!

Another thing: where can i found documentation that explain the rules for set colilo and colilo kernel command line?

Thanks and regards,
Gianluca Salvador

Hello all

Someone looks have send to Gian good answer for this trouble, is it possible to have here this answer? I have exactly the same problem
Linux boot and stop after display:

Coldfire internal SEC driver version 0.11

Please help

Thanks a lot

Olivier

Re: Linux booting halts

Gian — Wed, 12 Jul 2006 13:52:55 GMT

Hi Olivier!

This is a kernel configuration issue. You need to disable:

Device Drivers --->
Misc drivers --->
[*] Security

Device Drivers --->
Memory Technology Drivers --->
[*} MTD support

After that it will work!

Gian

Really thanks, now it work until kernel panic because it can't connect NFS server as you notice!

I'm going to try solve this, perhaps have the solution?!!!

Gian — Thu, 13 Jul 2006 14:06:07 GMT

Unfortunately yesterday i tried to put colilo in boot-flash (and so erasing DBUG) to avoid the kernel image's download and the net-parameters settings every time. The colilo image work from RAM, but NOT from FLASH!!!!!
So now i must restore the DBUG monitor through BDM interface...
At now i didn't resolve the nfs problem yet, so the first do it, could help the other, ok?
Bye,
Gianluca

Re: Linux booting halts

OL — Fri, 14 Jul 2006 03:53:01 GMT

Hello

There is a specific colilo for flash, and it is wrote it is possible to have dbug and colilo on the flash.

For NFS, of course if I find something I put some information here, probably this is a mistake on NFS server config.

Olivier

Hello

Some news, NFS not work but messages change!

Perhap do you not have "portmap" service running?

I have notice a strange problem configuration I have put something like this for IP address that can access to my NFS server: 192.168.1.*
and it looks not work I have replace it by: 192.168.1.0/255.255.255.0
This was need for me for test NFS server from my computer

as root I have done this sort of test:
mount 192.168.1.39:/tftpboot/ltib /mnt/ltib

You should be able to mount it, for me it work

Now I have probably to look in NFS right, I not understand how the coldfire card is identify.

Thanks guys,

This was just the info I needed.
I've started working on coldfire-linux almost 2 months now, and
this trick helped a great deal.

I don't have the final answer to the "kernel panic", but I got it running with a workaround: I exported the original directory in which the root-file system is generated by LTIB (/my-ltib-root-dir/rootfs) directly, in stead of using the link in /tftpboot.

I'm new to linux but for your information, this is how it worked:
I used the /etc/exports - file and added:
/path-to-my-ltib-root-dir/rootfs 192.168.1.202(rw,async,no_root_squash)

in which "192.168.1.202" is the IP-address of my target board

Remarks:
* In the setup for the command-line (colilo>set cl mac0= ... etc etc) refer directly to:
nfsroot=my-host-IP-address:/path-to-my-ltib-root-dir/rootfs

* When I do the start-up sequence I have to switch serial communication to 115200 baud-rate, after the linux kernel has started.

Hi OL!
Some news: now my nfs seems work a little bit...
I have updated my nfs-utils, changed the /tftpboot permissions in 775 and now during the kernel execution, it said

nfs: RPC call returned error 101

and here stops.

So i don't know if there is an nfs problem still, but i didn't understand why it has tried to setup eth0 an other time. Perhaps, the gw is wrong... and maybe this could be the origin of the 101 error problem...
If you have any suggestion...

Hi to all!
I have linux prompt on ColdFire!!!!!!!
I solved the nfs problem and also the last problem. That was a eth0 setup issue: In fact i rebuild the linux kernel image checking the dhcp flag for the ethernet configuration. Now i have -sh-2.05b# and theworld is beautifull :smileywink: almost untill the next problem ;-P
