370-wl4030 using 99% cpu

hola desde Chile :)

I'm testing an IGEP module (IGEP Kit with Paris board)
I'm using the bundled yocto (1.2) image and trying to launch a simple X application
Now, the board is running really really slow, with 378-twl4030 process eating all the cpu:

308 root -51 0 0 0 0 S 99.0 0.0 8:47.63 irq/378-twl4030

and this message in dmesg every second:

[636.137542] musb-hdrc musb-hdrc.0: configured as A device timeout

I blacklisted the twl4030 module with no luck
kill -9 308 does not work

Any ideas on what could I do?

Thanks

First of all download the attached patch. Then apply the patch an rebuild the kernel
$ patch -p1 < disable-otg_defconfig.patch
$ make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- igep00x0_defconfig
$ make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- zImage modules


Install the new kernel, and boot again.

    Hi slara, Which application are you trying to launch ? If is a custom application can you provide the source code and I'll try to reproduce the issue ? Thanks.

    I'm testing qtwebview from git.isee.biz, but the problem happens with the default sato image too. To run qtwebview I had to install qt4-embedded shared libraries on the device and add a modified ~/.matchbox/session file Thanks.

    In that case I'll recommend that you don't use the sato image. Instead of default image use the qt4e-demo-image as is optimized to run QT.

    See how to create a SD-card with the qt4e-demo-image at :

    The you can install the qtwebview inside

    OK, I made an qt4 demo image but I got the same error without installing qtwebview, just the image

    The system starts but really slow. The touchscreen is unresponsive almost all the time.

    thanks for the help.

    I have nothing connected to Paris USB or USB OTG. Just Paris with IGEP Comm module, power and ethernet.

    Can you try to build a new kernel without USB OTG support and put it into the PARIS ? If you need some help on how to do this I'll be in the IRC, you can contact with me.

    Better,

    The_Linux_kernel

    You should only replace the kernel.

    I'm trying to build the isee kernel following

    http://labs.isee.biz/index.php/The_Linux_kernel

    For the normal configuration, everything looks fine, kernel compiles and boots. Now, if I make any USB OTG related change in .config file (manually or with menuconfig), before or after loading igep00x0_defconfig, the .config file is overwritten on
    make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- zImage modules
    .

    I had tried to modify the arch/arm/configs/igep00x0_defconfig file and remove the .config.old but no luck.

    How should I remove the USB OTG support form the build? Thanks
