    Hi all,  I am using a adsl box (PSB 7200) with tnetw1350a wifi chip on it. I have tried to run it with OpenWrt, every thing is OK, but the wif and usb could not work.
    I received the following line:

    acx: this driver is still EXPERIMENTAL
    acx: reading README file and/or Craig's HOWTO is recommended, visit http://acx100.sf.net in case of further questions/discussn

    Any one have ideas?

    Hello lvqier,

    Your are probably trying the old acx driver.

    Could you try the acx-mac80211 version of the git mac80211-mem branch (see ) ?

    The OpenWrt trunk also contains an acx-mac80211 package (see ), which uses the code of this branch. In the Makefile you can easily change to a recent commit. Current commit in repo is 47e8758c.

    I'm running this code with OpenWRT trunk on a WAG54G and DG834Gv2, both TNETW1130. It's under development, but 1350 support is at least configured in the vlynq part, so there might be chance it already works.

    For what router model and version is it exactly ?

    git://gitorious.org/~oli1417/acx-mac80211/oli1417-clone.git, branch mac80211-mem
    https://dev.openwrt.org/browser/trunk/package/acx-mac80211

    Cheers, Oliver

    Next week I'll only have limited internet access, so in case there might be some delay in response.

    Thanks, Oliver
    I will try your advise on weekend.

    The router I'm using is ZXV H608B v2 which OEMed by China Telecom.
    It is an ADSL box with hardware below:
    CPU: PSB 7200
    RAM: 32M
    Flash: 16M (14 mtd blocks, some are used to back up the OS)
    Wifi: TNETW1350A
    USB Host: ISP1160/01 (It have 2 USB slots.)
    Switch: ADM9669

    BootLoader is ADAM2 and the OEMed Linux kernel is 2.4.17

    Wow, what a very nice hardware, lots of reasons to try to make it work on OpenWrt. :)

    Note that TNETW1350A is of course slightly newer, thus it might be very advisable to go via the existing new Android-originated driver in the kernel, since it should almost support this chipset as well, and especially since our driver is doomed from a legal point of view.
    I unfortunately failed to realize early enough that the new Android driver has shockingly similar amount of support code - despite supporting a newer chipset generation -, thus I could not advise Oliver in time to go via development of that driver instead of getting burnt in a legal sense by doing lots of very nice work on ours (or, IOW, it would have been much better to spend further development on the legally cleared mainline driver instead of doing lots of work on our driver with legal issues).

    So if you feel experimental enough, try to make the mainline-based driver do something, and TRY TO AVOID directly working with our driver in case your work on the kernel driver is promising.

    Hello,

    Ok, then we should check this possibility of the Android driver in more detail. And in the meanwhile maybe deactivate support for the newer chips (TNETW1350..+, if anyway working), so that only the old one's (TNETW1100,1130) remain, for which also the previous driver was there already.

    And then work also on the clarification of the open legal question, maybe also in the light of the other similar drivers.

    So for TNETW1350, it's better to have a look at the Android driver.

    Oliver

    First, thank you.
    I have tried the acx-mac80211 driver in the openwrt trunk from http://downloads.openwrt.org/snapshots/trunk/ar7/packages/.
    The driver failed to work again. This time I received boot message:

    ...
    Registered led device: status

    ...
    

    After read the acx source code from git://gitorious.org/~oli1417/acx-mac80211/oli1417-clone.git.
    I think "acx: acx: eCPU is already running. reset_dev() FAILED" caused by wrong reg address:

    // IO_ACX_ECPU_CTRL ?
    ecpu_ctrl = read_reg16(adev, IO_ACX_ECPU_CTRL) & 1;
        if (!ecpu_ctrl) {
            msg = "acx: eCPU is already running. ";
            goto end_unlock;
        }
    

    What's more, I write a email to the ti technical support, but they reply me that the tnetw1350a is a very old wifi chip for OEM solutions, and they refuse to answer anything about this chip.

    There is another bad news, that I can't remove the acx_mac80211 module. When executing "rmmod acx_mac80211", I received a segmentation fault:

    Hello lvqier,

    Thanks a lot for trying this out. Unfortunately this basically means, that the TNETW1350 is not supported by this driver. And as suggested above, it would possibly be better to see this with the Android driver. In this driver we'll probably remove the device id, so that the driver also doesn't claim it anymore.

    Anyhow, thanks a lot for having checked this :)!

    Best Regards, Oliver
