VPSS firmware with gstreamer 0.4 on DM8148?

Scott Shumate

Other Parts Discussed in Thread: TVP7002

Following the wiki page for the gstreamer DM81xx plugin (http://processors.wiki.ti.com/index.php/DM81xx_Gstreamer_Plugin), I was able to compile and install the new 0.4 version of gstreamer (TAG_GST_DM81XX_00_04_00_00) onto our EVM8148 board. We want to use the newly released v4l2src support to capture video using gstreamer. However, when I load the capture driver (ti81xxfb), I get the following:

root@dm814x-evm:~# modprobe ti81xxvin
tvp7002 3-005d: tvp7002 found @ 0x5d (OMAP I2C adapter)
omap_i2c omap_i2c.3: controller timed out
omap_i2c omap_i2c.3: controller timed out
omap_i2c omap_i2c.3: controller timed out
omap_i2c omap_i2c.3: controller timed out

tvp7002 3-005d: TVP7002 read error -110
tvp7002: probe of 3-005d failed with error -110
ti81xxvin ti81xxvin: Error registering v4l2 subdevice

According to the DM814x Video Driver User Guide (http://processors.wiki.ti.com/index.php/DM814X_AM387X_VPSS_Video_Driver_User_Guide), one must use the PSP version of the VPSS firmware with the ti81xxvin driver due to conflicts on the I2C bus to the TVP7002. However, the PSP VPSS firmware does not work with the EZSDK which gstreamer requires. This puts us in a catch-22 of VPSS firmware versions.

So, which version of VPSS firmware to use for the gstreamer 0.4 v4l2src component with the ti81xxvin driver?

Thanks,

Scott

I'll attempt to answer my own question. Through a few trial and error attempts from putting together information from several posts, I was able to get figure out the answer. First, you must load the dm814x_hdvpss_v4l2.xem3 firmware instead of the dm814x_hdvpss.xem3 firmware. Both are found in /usr/share/ti/ti-media-controller-utils/. Second, you must change the i2c_mode for the vpss kernel module from i2c_mode=1 to i2c_mode=0. Thus, /etc/init.d/load-hd-firmware.sh is changed to:

        <snip>
        firmware_loader $HDVPSS_ID /usr/share/ti/ti-media-controller-utils/dm814x_hdvpss_v4l2.xem3 start
        modprobe vpss sbufaddr=0xBFB00000 mode=hdmi:1080p-60 i2c_mode=0
        <snip>

After that, the ti81xxvin module loads without error.

Hopefully, TI can document this in the relevant wikis.

Hey ,

i still have errors when i tried to load ti81xxvin ..

there's anything else that i should do to make it work ?

my /etc/init.d/load-hd-firmware.sh is :

Hey Scott Shumate ,

Can you please publish /etc/init.d/load-hd-firmware.sh ?

or just attached it ?

thanks ..

############################################

when i2c_mode is 0 i get an i2c error ,

but when i2c_mode is 1 everything suppose to be ok

but still i having the same error with ti81xxvin (i2c_mode=0 same as i2c_mode_1)

any idea ?
