I have a set top box with an EM8471. Which Windows driver do I need to download to get the right firmware ?
I will test with kernel 2.6.24.2 , the box has a Geode SC1200 CPU.
Christophe
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
You must download driver for REALmagic Xcard from site of Sigma Designs http://www.sigmadesigns.com.
Firmware can be extracted as described in README from:
1. file rm847x.sy_ in the archive XC_2_1K1.zip
or
2. file rm847x.vx_ in the archive XC_2_1W1.zip
I am not sure that your box currently supported by opensigma driver. Could you load sigma-test.ko
module into kernel running on box and post here output of dmesg?

OK.
I compiled (had to replace create/destroy_device_class by create/destroy_device).
The installed modules en firmware and manually modprobed em8471. No messages at all. I did see in /proc/devices
213 sigma, but I did not see new device nodes (that can also be a local udev problem).
Loading the sigma-test module logged:

old driver
--------------
I have no idea -> I recycled old hardware at the company I work, but the hardware design was done by another company. I do know that they used Linux 2.4.20, and I have a binary module for that
I have similar set top box and I am trying to make EM8471 working. I have built kernel modules succesfully but they are not loaded at startup. When I try to load xcard module manually, it is loaded together with some other modules but I do not have any messages from them in dmesg.
Does yor box load any opensigma modules at boot?
Are you getting any messages from them in dmesg?
Some more info on my box is in Open Discussion forum.
Wojciech
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
the reason you did not see messages after loading the modules could be because the xcard module does not recognize the PCI id.
You can make the following change to xcard.c :
645c645
< { VENDORID_SIGMAD, 0x8471, PCI_ANY_ID, SUBID_XCARD, 0, 0, 0 },
---
> { VENDORID_SIGMAD, 0x8471, PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0 },
and try again.

Good Job
Let me tell you some notes:
1. You can start X-server via created /dev/fb0 device, OSD is working via framebuffer
2. Be carefull with microcodes: I expect You have to use microcode for revision C of em8471.
3. Devices can be created manually
mknod /dev/sigma/em8xxx0 c 213 0
mknod /dev/sigma/video0 c 213 1
mknod /dev/sigma/audio0 c 213 2
mknod /dev/sigma/spu0 c 213 3
Good luck
And some question: Are you using the box based on Geode SC1200 CPU or some other hardware?
Sergey
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
- So I have to use an X server based on the framebuffer driver ? Currently I use the 'nsc' driber -> will change it
- I do use the revision C, I don't what 'symbol L21_Buf2 not found ' means ?
- the devices are created automatically, once I patched xcard.c
- Indeed the tests are done on the Geode SC1200 based box.
tests
-------
** video
I tested sending an mpeg2 to /dev/sigma/video0 , but it didn't work, but then again I used the wrong X. Do I need X also for mpeg display ?
In the log I see lots of messages like
sigma_isr
Video threshold interrupt
Time: 315533881.147190
sigma_isr
Video threshold interrupt
Time: 315533881.167516
sigma_isr
Video threshold
** sound
catting an mp3 to /dev/sigma/audio0 gave an error 'no space left on device'
I will retry the tests with a framebuffer based X.
Best regards,
Christophe
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
1. Don't change your currently 'nsc' configuration of X-server. Create the new config file xorg.conf.fb0 in the /etc/X11 directory with next strings in the "Device" section
Driver "fbdev"
Option "fbdev" "/dev/fb0"
After this you can start the second X-server by the command
startx -- :1 -config xorg.conf.fb0
2. > I don't what 'symbol L21_Buf2 not found ' means
There is little problem of microcode for em847x rev. C used in windows driver. It is quite good for usage. The another versions of microcode doesn't have this problem.
3. Geode SC1200 based box
Nice. Have you tested this box with old Sigma Designs's driver?
4. About video
You have to use pure mpeg2 video stream. It can be created by mencoder via splitting usual mpeg2 file into video and audio streams.
To disable debug messages remove '-DSIGMA_DEBUG=1' from Makefile
5. I will fix audio issues
Sergey
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
it does not work yet. Do I need to run both X servers at the same time ? As soon as I start the second one (fbdev based) the screen turns black. Running the second one alone also only shows a black screen.
When I cat a pure video-only ES mv2 file to /dev/sigma/video nothing happens, except for the debug messages listed before.
What else should be in xorg.conf.fb0 ?
About the old Sigma drivers : I did not test them, because I had only a incomplete software load, based on Linux 2.4.xx. I don't even know if X was used.
Regards,
Christophe
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Actually the blank screen can be via video pinout inconsistence between xcard and your top box. Try to use module ventura4k.ko instead. It is intended for other Sigma's PCI board based on em8471 chipset
The sound is broken. I will add support of sound to test your box

old driver
--------------
I have no idea -> I recycled old hardware at the company I work, but the hardware design was done by another company. I do know that they used Linux 2.4.20, and I have a binary module for that
#/sbin/modinfo realmagic84xx.o
filename: realmagic84xx.o
kernel_version: 2.4.20-myrio-I3M
parm_quasar_dev_id:h
But I've never got Linux 2.4 to work properly on the box , and my interest is 2.6 anyway

Well, thx for infos ;-)
I will add support of your board in the nearest future
Sergey
That would be amazing !

Hello Christophe and others!
I have similar set top box and I am trying to make EM8471 working. I have built kernel modules succesfully but they are not loaded at startup. When I try to load xcard module manually, it is loaded together with some other modules but I do not have any messages from them in dmesg.
Does yor box load any opensigma modules at boot?
Are you getting any messages from them in dmesg?
Some more info on my box is in Open Discussion forum.
Wojciech
Hello Wojciech ,
the reason you did not see messages after loading the modules could be because the xcard module does not recognize the PCI id.
You can make the following change to xcard.c :
645c645
< { VENDORID_SIGMAD, 0x8471, PCI_ANY_ID, SUBID_XCARD, 0, 0, 0 },
---
> { VENDORID_SIGMAD, 0x8471, PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0 },
and try again.
Regards,
Christophe
Support of your hardware will be added during next few days. I am working on it now
Sergey
Hello all
I finally have an environment that let's me better test the box. I will follow the commits here and post test results.

Good Job
Let me tell you some notes:
1. You can start X-server via created /dev/fb0 device, OSD is working via framebuffer
2. Be carefull with microcodes: I expect You have to use microcode for revision C of em8471.
3. Devices can be created manually
mknod /dev/sigma/em8xxx0 c 213 0
mknod /dev/sigma/video0 c 213 1
mknod /dev/sigma/audio0 c 213 2
mknod /dev/sigma/spu0 c 213 3
Good luck
And some question: Are you using the box based on Geode SC1200 CPU or some other hardware?
Sergey
Hello,
- So I have to use an X server based on the framebuffer driver ? Currently I use the 'nsc' driber -> will change it
- I do use the revision C, I don't what 'symbol L21_Buf2 not found ' means ?
- the devices are created automatically, once I patched xcard.c
- Indeed the tests are done on the Geode SC1200 based box.
tests
-------
** video
I tested sending an mpeg2 to /dev/sigma/video0 , but it didn't work, but then again I used the wrong X. Do I need X also for mpeg display ?
In the log I see lots of messages like
sigma_isr
Video threshold interrupt
Time: 315533881.147190
sigma_isr
Video threshold interrupt
Time: 315533881.167516
sigma_isr
Video threshold
** sound
catting an mp3 to /dev/sigma/audio0 gave an error 'no space left on device'
I will retry the tests with a framebuffer based X.
Best regards,
Christophe
Hi,
1. Don't change your currently 'nsc' configuration of X-server. Create the new config file xorg.conf.fb0 in the /etc/X11 directory with next strings in the "Device" section
Driver "fbdev"
Option "fbdev" "/dev/fb0"
After this you can start the second X-server by the command
startx -- :1 -config xorg.conf.fb0
2. > I don't what 'symbol L21_Buf2 not found ' means
There is little problem of microcode for em847x rev. C used in windows driver. It is quite good for usage. The another versions of microcode doesn't have this problem.
3. Geode SC1200 based box
Nice. Have you tested this box with old Sigma Designs's driver?
4. About video
You have to use pure mpeg2 video stream. It can be created by mencoder via splitting usual mpeg2 file into video and audio streams.
To disable debug messages remove '-DSIGMA_DEBUG=1' from Makefile
5. I will fix audio issues
Sergey
Hi,
it does not work yet. Do I need to run both X servers at the same time ? As soon as I start the second one (fbdev based) the screen turns black. Running the second one alone also only shows a black screen.
When I cat a pure video-only ES mv2 file to /dev/sigma/video nothing happens, except for the debug messages listed before.
What else should be in xorg.conf.fb0 ?
About the old Sigma drivers : I did not test them, because I had only a incomplete software load, based on Linux 2.4.xx. I don't even know if X was used.
Regards,
Christophe
Have you get any console output on the TV?
Actually the blank screen can be via video pinout inconsistence between xcard and your top box. Try to use module ventura4k.ko instead. It is intended for other Sigma's PCI board based on em8471 chipset
The sound is broken. I will add support of sound to test your box
Sergey
Hello,
> Have you get any console output on the TV?
Without the xcard console I can have video console output if I hack the Linux geode framebuffer driver to enable TV out (but the image is bad).
With the xcard driver loaded I see nothing, when starting X-fb X-nsc disappears and I see a black screen.
What I haven't tried yet (lacking a keyboard) is to switch to virtual console 1 to see if I get a framebuffer console with the xcard module.
I'll let you know and will also try the other module.
Best regards,
Christophe
Hello!
I am trying to compile SVN version 14 but I get the following error:

The same is with SVN 13, SVN 12 was building OK.
Where the missing missing identifier should be declared?
I have kernel 2.6.29 on this machine.
Wojciech
Hi
Remove that string or use revision 12
Sergey
Christophe
The messages like
Video threshold interrupt
Time: 315533881.147190
sigma_isr
mean that decoder is OK and processing of video stream is workable.
