gumstix

Hi

I am trying to compile helloworld for an Overo Fire as follows:

/home/rsumman/oe/tmp/cross/armv7a/arm-angstrom-linux-gnueabi/bin/gcc
myHelloworld.c -o myHelloworld

and in doing this the following error is thrown:

gcc: error trying to exec 'cc1': execvp: No such file or directory

I have read elsewhere that there is likely to be something wrong with the
gcc installation if such an error occurs so I deleted /oe/tmp and did a
bitbake omap3-console-image to regenerate the tmp directory, however, this
didn't alleviate the problem. I am doing something stupid?

Any help is appreciated

Cheers

Titusgroan

======================

You can set the ip address as a kernel command line parameter so you don't
need dhcp. 

ip=<client-ip>:<server-ip>:<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>

See the kernel Documentation/filesystems/nfsroot.txt

For example, here are some settings I have in a u-boot environment
192.168.10.2 is the dev box/nfs/tftp
192.168.10.51 is the overo
192.168.10.1 is a router
water is the host name for the overo

// these are for tftp loading the kernel (for other folks who might be
reading this)
ipaddr=192.168.10.51
serverip=192.168.10.2
netmask=255.255.255.0
// i just took a MAC from a booted overo
ethaddr=02:E5:E8:85:90:F5

// these are for nfsroot using a fixed ip address passed to the kernel
nfsroot=192.168.10.2:/exports/water
ip=192.168.10.51:192.168.10.2:192.168.10.1:255.255.255.0:water:eth0:none
nfsargs=setenv bootargs console=ttyS2,115200n8 vram=12M root=/dev/nfs
rootfstype=nfs ip=${ip} nfsroot=${nfsroot} rootwait

// and here is how you would use them in the style of the gumstix u-boot
// to tftp load the kernel
tftp ${loadaddr} uImage

// and/or for the nfsroot
run nfsargs

bootm ${loadaddr}

Hello all,
   I've always been using my Verdex XL6P with consoleLCD-vx expansion
board and now want to start playing with my audistix. I've gotten very
used to having a console output on the consoleLCD-vx going to a serial
port and audiostix don't have a serial connection, it does have a USB
connection, which I don't really want to use for console as I'll need it
for other things.

Is connecting up the console on the audio stix as simple as soldering to
the Serial port BTUART, HWUART or FFUART?

Thanks for any help

I am using a gnome 9r8 version for overo fire and summit machine. I need to
do an autologin in order to have access to remote destop without to writte
login and password.

I modify the gdm/custom.conf file following
http://library.gnome.org/admin/gdm/2.27/gdm.html 


[daemon]
TimedLoginEnable=false
TimedLogin="my login"
TimedLoginDelay=30

Then I copy a gdm file to a gdm-autologin file in pam directory with the
following ( http://library.gnome.org/admin/gdm/stable/security.html.en) 

gdm-autologin auth  required    pam_unix_cred.so.1
       gdm-autologin auth  sufficient  pam_allow.so.1
       gdm-autologin account  sufficient  pam_allow.so.1
       gdm-autologin session  sufficient  pam_allow.so.1
       gdm-autologin password  sufficient  pam_allow.so.1

Then I reboot, the first screen show that is autologging, but after a few
seconds a message appear (login denied).


So, i don't know how to resolve this,,, Coudl you fix it?

Hi all

 

I have reflashed the gumstix board via serial port. I used connex root file system image and kernel. The reflashing process is done successfully. After I type "bootm" it can reboot and start the kernel succesfully.

 

The problem is that once I power off and reboot the board, after gumstix completes scanning the jffs2 file image, it prompts "inode failure" and stops booting.

 

Anyone who has met the same problem before? Suggestions would be highly appreciated. I am really frustrated by this. Thank you very very much for your time and help.

just to document this in case others run in to the same issue:

i wasn't able to figure out how to do this at build time (if someone knows
any help would be most appreciated!) What i did do was copy over
corresponding config files from my "trial" gumstix to the buildroot file
system on my host.

On the gumstix, i ran:
# adduser lowuser # replace "lowuser" with your desired username
# addgroup lowuser

i then copied over the corresponding entires for 'lowuser' from the
following files to corresponding buildroot folder 
cp /etc/passwd /home/gumstix/build_arm_nofpu/root/etc/
cp /etc/shadow /home/gumstix/build_arm_nofpu/root/etc
cp /etc/group /home/gumstix/build_arm_nofpu/root/etc

then when i issue a rebuild and reflash my board, the user settings are
automatically retained. it would still be nice to be able to do this as part
of the build, so that user names could be controlled by a script, but this
works too. i can append the appropriate user lines to the corresponding
files (e.g. cat newusers_passwd >> /etc/passwd; cat newusers_group >>
/etc/group) 

i also had to manually create a home folder for each user, else the log in
process might seem to "hang" as it tries to enter the users home folder. 

mkdir /home/gumstix/build_arm_nofpu/root/home/lowuser

cheers,
hypo

I'm pretty new to Linux. I'm having a problem with the build process.
Any ideas on how to solve this problem would be appreciated?

Thanks.
