Use GADMEI UTV380 in fedora 10


Recently, I had bought a Gadmei TV box(UTV380) and need to be used in my fedora 10. Is it possible for me to find the linux driver for Gadmei UTV380? and how can I install it in fedora 10?Thanks.

http://linuxtv.org/wiki/index.php/Ga...B_TVBox_UTV380

Overview/Features

It has Television and S-Video inputs via Two separate 3.5mm tail cables
It falls under V4L's "Em28xx devices" category (being based upon an EM2860 usb bridge)
Components Used
Verified using dmesg as well as physical inspection of the PCB.
Empia EM2860 (USB video bridge)
Empia EMP202 (AC'97 audio processor)
NXP/Philips SAA7113 (video decoder)
Xceive XC2028ACQ (Analog chip tuner)
24C04 (EEPROM)
HCF4052 (4-channel Analog multiplexer)
Other Pictures
Current Status
Currently it works after patching the v4l-dvb.
Need to test the sound and Composite inputs.
Update: I tried the sox command to route the /dev/dsp1 to /dev/dsp, but it thrown error saying /dev/dsp1 is already locked and cannot open. I think it is due to the pulse audio already locked it. But still I can't get any sound may be some gpio registers deed to be set or the device definition needs some change. Any inputs are welcome. I am testing this on ubuntu Lucid 10.04 64-bit.
Will release the patch soon.
I need help on releasing this as a Patch upstream.
Anybody interested can contact me jeevas.v AT gmail.com
To make it work
I have done these changes to make it work.
1. extract the Xcieve firmware for xc2028 and copy to /lib/firmware as mentioned in the em28xx page.
2. extract the latest v4l-dvb source as mentioned in the em28xx page.
3. go to v4l-dvb/linux/media/video/em28xx folder.
4. edit em28xx.h file and add the device:
.
.
#define EM2870_BOARD_REDDO_DVB_C_USB_BOX 73
#define EM2800_BOARD_VC211A 74
#define EM2882_BOARD_DIKOM_DK300 75
#define EM2860_BOARD_GADMEI_UTV380 76
.
.
5 edit em28xx-cards.c and add the card in card definitions
.
.
.
[EM2860_BOARD_GADMEI_UTV380] = {
.name = "Gadmei UTV380",
.tuner_type = TUNER_XC2028,
.tuner_gpio = default_tuner_gpio,
.has_dvb = 0,
.decoder = EM28XX_SAA711X,
.input = { {
.type = EM28XX_VMUX_TELEVISION,
.vmux = SAA7115_COMPOSITE2,
.amux = EM28XX_AMUX_VIDEO,
}, {
.type = EM28XX_VMUX_COMPOSITE1,
.vmux = SAA7115_COMPOSITE0,
.amux = EM28XX_AMUX_LINE_IN,
} }
},
.
.
.

And also add the card's usb id in the list if it is not already there.
.
.
{ USB_DEVICE(0xeb1a, 0x50a3),
.driver_info = EM2860_BOARD_GADMEI_UTV380 },
.
.

6. Edit em28xx-core.c and make sure that the AC97 audio processor is properly detected. In this case I have to add one more vendor based on the dmesg output.
.
.
/* Try to identify what audio processor we have */
if (((vid == 0xffffffff)||(vid == 0x83847650)) && (feat == 0x6a90))
dev->audio_mode.ac97 = EM28XX_AC97_EM202;
else if ((vid >> 8) == 0x838476)
dev->audio_mode.ac97 = EM28XX_AC97_SIGMATEL;
.
.
7. Then execute the following commands to build and install the kernel modules.
sudo make distclean
sudo make menuconfig (Due to some error I have to disable one of the modules in the list to get past the compilation).
sudo make
sudo make install
8. After this restart your machine, plugin your device and start your favourite tv app and enjoy.
