'msh' on 'ltib-cf_nommu-20081215' can not execute 'rcS' ( neither any other script )

Hi,

 

This is a problem on custom board based on LOGICPD 5373EVB, with ltib-cf_nommu-20081215

BSP.

 

The 'msh' shell can not execute the rcS script ( neither any other script ). As soon as the booting proces

arrives to  'inittab' line "::sysinit:/etc/rc.d/rcS" it hangs up maybe up to 30 minutes, and finally prints 

on console:

 

$ ./rcS start
out of string space
$

 

What does mean 'out of string space' ???

 

 But system is not set.

 

I have achieved to initialize the whole system by adding all need setups on inittab as:

 

console::sysinit:/bin/mount -n -t proc proc /proc
console::sysinit:/bin/mount -n -t sysfs sys /sys
console::sysinit:/sbin/ifconfig eth0 102.128........
console::sysinit:/bin/mount -a

 

instead of calling the rcS....

 

But i need to execute scripts on my application!!!

Yes, I found the same problem these days, the kernel hangs about 30 minutes to complain

 

"input line is too long" and

"/proc/sys/vm/min_free_kbytes: cannot create

/proc/sys/vm/vfs_cache_pressure: cannot create"

 

but only when i use dBug(4d.1a.1e), if i use u-boot, the kernel just boot OK!

Hi Elias!

 

I think your information can be very usefull for me!!!

Unfortunatelly is not easy for us to change the bootloader to u-boot, because we use dBUG to setup some other hardware on our board.... but

 

Can you post ( or send me ) your linux start-up messages??, maybe there is some in kernel configuration that is not properly done via dBUG, maybe we are missing something on the kcl???

 

Thank you in advance;

 

Oscar.

Hi Oscar,

 

I found nothing special different between dBug startup message and U-boot's.

I had that problem initially after moving to ltib-cf_nommu-20081215. My project is using the dBug bootloader and MCF5328 custom board based on the MCF5329EVB.  I never did pinpoint the problem, but it went away after disabling several things I didn't need that were defaults in the BSP. I am not using CAN, eDMA, rtc. I changed some of the USB options, some of the USB features I load as modules. I also changed some of the busybox options. If I get time I will try to reproduce this and find what specifically is causing it.

Hi! ( here we are after vacation)

 

Elias, thanks a lot for your reply, i will study carefully!!!

 

obidon, ok it seems there is some 'wrong setting' on ltib-cf_nommu-20081215. In fact we have disabled almost everything on our board but the USB too, but in our case all regarding USB is compiled in the kerenel not as module ( maybe the problem is on USB?? ). Thanks a lot really!!!

Hello again;

 

Really both boot traces are identical. Just one diference that is supposed to be booting 'independent';

uboot uses a compressed image and dBug a binary image.

 

Maybe booting binary image in uboot has the same result?

 

obidon, are you using binary or compressed image on your working board?

 

I'm going to test it on my board.

 

Oscar.

Sorry, I've been away. I am using a bin image and never did use a compressed image. I have 32M Spansion NOR on the board so no need for a compressed image.
