    hi everyone!

     

    I am trying to boot an SH7751R evaluation board using embedded linux. The kernel image that came with HHL preview kit works fine, except that it lacks some configurations i need. Thus i had to compile my own version of the kernel. However, after several kernel size reductions, i am left with a kernel that cannot be loaded at all. I get the error:

    Code:
    Looking for port of RPC 100003/2 on w.x.y.zportmap: Server w.x.y.z is not reponding, timed outRoot-NFS: Unable to get nfsd port number from server, using defaultlooking up port of RPC 100005/1 on w.x.y.zportmap: server w.x.y.z not responding, timed outRoot-NFS: Unable to mountd port number from server, using defaultmount: server w.x.y.z not responding, timed outRoot-NFS: Server returned -5 while mounting /opt/...VFS: Unabvle to moung via NFS, trying floppy...

    i do not get this error in the old kernel. is nfs dependent on any other module/configuration in order to work?

    Hi Guys!

     

    Is it possible for me to measure the performance of several peripherals in a given board? Lets say if i want to measure the speed of my ethernet peripheral, do i have to create kernel modules for this? or should i only get a tool for measuring network performance?

    My goal is to see how the OS drives these peripherals and see if there is any overhead.

    Thanks everyone!

    Hi all!

     

    I have a problem with booting via DHCP. I have a target MS7751RSE01 board and i am trying to boot Embedded linux via dhcp. I finally got everything to be working except the error No HOSTNAME is available.

    I hope you guys have some ideas about this.

     

    Code:
       #dhcpd.conf   allow bootp;   subnet 192.168.213.0 netmask 255.255.255.0 {     default-lease-time xx;     maximum-lease-time xx;     group {        host 192.168.213.216 { #this is the IP of my host. I also tried 127.0.0.0             hardware ethernet 02:00:00:00:00:33;            fixed-address 192.168.213.22;            filename "...";            option root-path "...";     }   }

    Thanks everyone!

    Hi!

    Just a quick question... is it possible to install 2 releases of RH in one PC? and both are using the same boot loader? I tried doing this and it seems to be impossible. Maybe there is a restriction I failed to read or there might be a work around on this one.

     

    Background: I am doing this because I have RH9 originally installed and HardHat dev kit i got is compatible with RH7.2 only. so i have to "downgrade" my OS to 7.2. Since many files are already in RH9, i got another HDD and installed RH7.2 there having GRUB bootloader of Enigma on MBR. I expected it to behave like RH + WinXX where i can choose which OS to boot, but it wasnt.

     

    Thanks everyone!

    Hope this isnt too far-fetched:

     

    Hi everyone!

     

    I am trying tofigure out the main difference between Linux OS and Embedded Linux.

    As far as i have read several articles, i couldnt determine whether or not embedded linux is capable of making an x86 processor work like a complete Linux OS can. Based on the fact that Embedded Linux kernel is just a trimmed Linux OS Kernel, i am thinking that it is possible, but there might be some other issues that i haven't stumbled upon.

     

    Thanks for your time!
