Re: Cannot build VPSS driver into kernel

Michael Edwards

For experimental purposes, it's easy enough to drop enough files from the ipc and syslink release tarballs into a directory in your kernel tree and add appropriate Kconfig/Makefile bits.  Here's the Makefile that works for me:

EXTRA_CFLAGS += -Idrivers/video/ti81xx/syslink -DSYSLINK_PLATFORM_TI81XX -DSYSLINK_VARIANT_TI816X -DSYSLINK_BUILDOS_LINUX -DSYSLINK_BUILD_OPTIMIZE -DSYSLINK_LOADER_ELF -DARM_TARGET -DC60_TARGET -DLOADER_DEBUG=1

obj-$(CONFIG_TI81XX_SYSLINK) += syslink.o

    Hi Yihe,

                  I also doubt the same. But in syslink user guide there is no such details about how to install syslink. So I referred  

    http://processors.wiki.ti.com/index.php/Android_am389x_build_procedure    and    directly copied the syslink.ko to rootfs/opt/syslink

    cp $SYSLINK_ROOT/ti/syslink/utils/hlos/knl/Linux/syslink.ko $NFS_ROOT/system/bin/syslink/

    If there are any such methods to install syslink.ko please specify.

    Or if there are any methods which install syslink.ko along with other kernel modules please mention.

    Or the path where I have to copy the syslink.ko

     

    Thanks for your reply Yihe,

    Anand Naik

    Anand,

    I am not sure how android load this. but the fundamental should the same. syslink.ko should be loaded at the first step

    1. insert syslink.ko

    2. /procmgrapp 2 ti816x_hdvpss.xem3(c6a816x_hdvpss.xem3)

    press ctrl+z

    3. insmod vpss.ko debug=1

    Regards,

    yihe

    Hi Anand,

    I believe you have to manually copy across syslink.ko then use "insmod" to load it if you are building the kernel yourself.

    In case you didn't find them, the Syslink documentation is in "ti-ezsdk_c6a816x-evm_5_00_00_56\syslink_02_00_00_56\ti\syslink\docs" and the particular file that might help you is called "SysLink_02.00.00.56_alpha2_InstallGuide.pdf".
