    Trying to get IDE working on Oleg's Firmware

    Hi,

    After managing to install Oleg's latest version on the WL HDD, I tried to get the modules from the ide folder of a Wl HDD stock firmware.
    The insmod give the following output. I don't know where to get the ide_ops symbol which looks like the starting point.


    Code:
    [admin@(none) /tmp]$ insmod ide-mod.o
    Using ide-mod.o
    insmod: unresolved symbol ide_ops
    [admin@(none) /tmp]$ insmod ide-disk.o

    Does anybody think it can be solved easily, or we have to wait fully tested firmware? What can I do to help testing this HD issue with Oleg's firmware?

    I've now a customized 1.1.2.7 available with telnetd, nfsv3 daemon, vsftpd and with harddisk drive watchdog disabled. I will inform Antiloop per PM and he will hopefully make it available on this site.

    You can take that as a basis for easily running all kind of apps.

    I would be indeed very interested by this firmware, but I also would like to use most of the standard wl500g fonctionality, including firewall,pppoe and dyndns with the wl hdd.

    I will for sure work from both side: ie using a firmware like yours from the wl hdd one, and trying to get from a wl500g one access to hd

    Do you think it would be possible to just use the ide*.o files or it would need a full redesign?

  4. #4
    I'd propose the other way around. Just "pull" binaries from wl500g and run them in the 1.1.2.7. If that doesn't work (uclib missing) compile them against gclib

    Guys, my idea was to made unified firmware sources for whole wl series. At the moment I've added WL-HDD to the Makefile, all wl-500g stuff is ready.
    At the moment I need someone who will take care of adding required webpages - most are just from wl-500g/gx, but this needs to be tested. ide stuff could be also added, by kernel recompilation, again there should be someone with good linux knowledge, who can made a required patch to wl500g kernel (if needed at all).
    The idea is not just wl-hdd support, but also adding wl-hdd features to upcoming wl500gx (I mean samba/nfs).
    Personally I do not own wl-hdd unit and I've have no plans to use it at all, that's why I'm calling for someone with wl-hdd.

    I'm currently trying to build minimal samba-2.0.9 to mimic wl-hdd functionality. But I need someone to help me with other stuff if there any interest at all...

    Hi Oleg, you can alway call on me to test things

    I'm ready to test as I'm dedicated to this right now. As I said in previous posts, I'm rusty on Linux, but I'm expert in network field and on Windows operating system.

    I'm ready to install a linux version on my PC if cygwin is not enough, and I've got time to dedicate for this at least this week at full time.

    hugo, the problem is that I do not have free time to work with wl-hdd also, I need someone who will start digging with sources.
    If you've experience in development, then probably you can start playing with it. But this is more than testing... If you're ready, then start with Fedora Core 2 installation on your PC.

    I'm actualy download and installing fedora core 2. This will take some time, but i'll report as soon as I'm able to compilate your own firmware from my computer.

    As for the web pages, it seems to me that the wl-hdd already has some equivalent, if you browse the www folder. They are definitly setting nvram value that are similar (if not the same) than the one from wl500g. I think they either stripped down a wl 500g firmware, or they wanted at some stage to add the wl 500 fonctionnality in the wl hdd before backing away from the idea.

    I think the only thing missing is a full menu to access all this pages, but it could be a good idea to create one simpler to be able to use this from a PDA for example.

    I will not be able to help for the ide thing soon, although I think this is really the only feature needed, as we can then easily add samba and ftp support to mimic the wl hd stock firmware.

    Tell me what kind of work you need for the webpages, and I'll take care of that.

    Well, in fact Antiloop also started looking into them, so you will probably need to cooperate with him.

    Ok, I'm ready. I've setup the build environment, made my first test, and I can properly build the wl500g firmware.

    I have the wlhdd source at hand too, so I can start to add the ide support to the kernel.

    Do you have some tracks for me to follow to add ide support? should I compile a new kernel, or try to make specific ide module? Just point me to the right direction and I will go as far as I can using my time and some google ;-)

    Do a 'make menuconfig' in both 500g and wl-hdd linux/linux sourcetree and compare the kernel configs.

    Furthermore in rc.c afaik there is a IDE define and the IDE module stuff is insmodded. You can probably copy paste that in the 500g sourcecode.

    But as I wrote before, it's easier to work in the other direction and "import" Oleg's stuff in the wl-hdd sourcetree. Anyway, whatever way you choose you'll learn a lot for sure

    Yes, just like the JockyW wrote. You need to enable ide support in the kernel and compile as modules.
    You can also compare .config files on the kernel dir - they contains all options enabled/disabled in the kernel. Try to figure out minimalistic options to reduce size of the kernel module (we do not need tape or floppy support, etc) - ASUS guys do not care about this.
    So, modify kernel config by adding new modules, compile firmware and check that they're insmoded ok and hdd could be manually mounted. Once done we can modify remaining parts of the firmware to do automatic insmoding.

    Ok,
    So I found the ide support in the .config from hdd and tryed to paste it in .config from wl500g.

    I also copied the pci and ide driver subfolders from hdd source.
    I tryed a make dep from linux folder, it worked
    I tryed a make from linux folder, it worked also

    but if i try a make from gateway folder, I get this:

    Code:
    make -C ide modules

    I don't know what's missing for getting pci_dev

    A search for it in the hdd source give me pages of result, so I suppose this is a standard library. Do you think it can be a file missing, or a bad compiling procedure?


    EDIT: here is what is for me the ide support in the .config from hdd . I also added scsi entry as they are also different. I used this section in the .config of wl500g

    Wl-hdd kernel is outdated version of one used in the wl500g. Do not mix kernel sources, try compiling wl500g kernel playing with .config only.
