Geoff
Now that's what works:
Works line-out - it comes with sound.
An internet radio, FM radio works.

What does not work:
No sound from speakers
"Select" and "Mode" button not working on reciver

I changed the configuration file. Made everything you wrote. Check the wires, traces of soldering. All the contacts. Everything is fine.  I did not touch anything anymore. Very carefully handled. I wiped the board with alcohol to remove traces of rosin

I am assuming that the 8711's headphone outputs on pins  9 and 10 are the signals which go to the power amps to drive the speakers.  And the outputs on pins 12 and 13 go to the Lenco's Line-Outs.  As you can see on the datasheet there is a volume control on 9/10 but not 12/13.  The volume would be set by control signals from the Barracuda module in response to the Vol+/Vol- buttons.

Edit:  Try the volume and mute buttons on the webserver remote control.  And does the OK button on that work?

If still no speaker sound I would suggest trying a factory reset.  This might disable all the Sharpfin stuff which would mean no telnet and no webserver.  Are you confident you can run the patchserver and re-install as described on the Sharpfin wiki?  (If your Select button is not working you need to use the menus to do the factory reset.)  The factory reset should not undo the line you added to /linuxrc.  After the reset you will need to re-enter all the network parameters.  The radio should work without the Sharpfin stuff.

Before trying the reset I suggest you use Sharpfin webserver's backup option to save a new set of firmware files in case you need to use JTAG again.  That set will contain the modified linuxrc and whatever network settings you are using now.

I changed the line-output and output to the amplifier. Appeared sound on line-out. Adjustable volume control. This suggests that because of something (most likely due to improper configuration or something I touched) has failed amplifier. But to repair it probably is easier than to load a new configuration. ))

And still does not work button mode. It is replaced with a button Select

Likely broke bipolar transistors in the amplifier. They are cheap. I will try to replace them.
The overall quality of installation fees are very low. As there is something not yet closed the factory, I do not understand. :)

The board itself is made King Champion. Amplifier board and the motherboard is MX-01i-L.

I don't understand what you mean about "adjustable volume control".

Also, I'd be surprised if you managed to break both left and right channels of the audio power amp if they are built from discrete transistors.

And I don't understand "As there is something not yet closed the factory, I do not understand. "

Did you mean that you changed wiring so that the pins 9 and 10 of the 8711 went to the Line-Out socket and you got audio with adjustable volume from there?  If yes, that does suggest the problem is the audio power output stages.  Check the power supply to them.  It is likely a different, higher voltage than the 5v and 3.3 volts to the digital circuits.

Yes, Geoff. I reversed the line-out jack and the input of the bass amplifier. Then just a needle touched the left and right channel wires, usually had to come buzzing. There is no. In the headphones Connect to line-out was sound, adjustable volume control. I checked the wiring tester. I measured the power to the integrated amplifier. The voltage on a 8.9. It is normal for him (which is allowed up to 15 volt). I checked the voltage of the stabilizers. There's two of the stabilizer to 3.3V, 3.3V voltage on them. Everything is normal. I want to replace the integrated amplifier BA5417 and 5 bipolar transistors. Because capacitors are intact, the resistors too.
Datasheet
http://www.ddrservice.info/files/Integrated-circuits/B/ba/5/ba5417.pdf

I think this is due to the fact that several times I made ​​a reset, shut off the power supply. External power supply, the voltage on it 9. When I connect it to AC 230V, slipped spark.

Geoff, the OP has asked me to send him a dump of the firmware on my Lenco. I have tried to make a dump using the Sharpfin 'backup' function, but when I click on 'here' to download the dunp file, I get "404 Not Found The requested URL was not found". Right-clicking and saving-as is no better; I just get 124-byte long files containing "<HTML><HEAD><TITLE>404 Not Found</TITLE></HEAD>
<BODY><H1>404 Not Found</H1>
The requested URL was not found
</BODY></HTML>". This is with Firefox: it is no better with IE. I also get the same result on other radios, no matter whether with Sharpfin 0.6 or Enhancement Pack 2.0.

Any ideas how to get this to work?
Radios in use: Roberts Stream 93i, Sangean WFR-29C, Technisat 450 & 520, Revo Pixis RX, Hama DIT2010 & DIR3100.

See further back in this topic.  http://recivarefuge.net/forum/index.php?topic=712.msg8329#msg8329 and some following posts.

The missing nanddump routine has been compiled as an addon but it did not work for me until I upgraded the webserver from 0.7.  That clobbered Enhance Pack 2.  I reinstalled EP2 which reverted the webserver to0.7 but the firmware backup still worked.

If you just make a backup from your Lenco as is, then when black007 JTAGs that, the radio will regain a non-functional display and non-functioning buttons and remote.  It will be configured for whatever network access yours is.  For him to gain telnet access you will need to tell him those details so that he can set up his network to match.  Alternatively if you (perhaps temporarily) add the bodge to /linuxrc (that hardcodes the Hardware ID) to your radio before you make the backup, then he will be able to use the radio's menu system to set his network configuration.  If you don't want to do that it might ease things a bit for him if you put your Lenco into ethernet and DHCP mode rather than Wi-Fi.

My understanding is that the firmware currently on your Lenco is only very slightly later than the -476 beta which black007 has running now.  Or is he asking for the latest official Lenco version and are you prepared to re-install that and re-install Sharpfin (and re-install the later firmware and Sharpfin and EP2 after making the backup)?

So that it is documented somewhere in case anyone should need to know in future.

There are two (at least) versions of the Lenco 2100 and they have different config files.

Dogmatix said that his 2100 has a Hardware ID of 854:

# MODULE:      config854.txt
#
# VERSION:     $Revision: 1.3.2.4 $
#
# DATED:       $Date: 2008-08-18 10:37:38 $
#
# AUTHOR:      John Stirling
#
# DESCRIPTION: Config file for config854 - kChampion MX-01i

When the Lenco 2100 of black007 was forcibly given the Hardware ID of 854 he found the Select and Mode buttons on the radio were swapped.  He eventually discovered that 628 was a better match.
# MODULE:      config628.txt
#
# VERSION:     $Revision: 1.1.4.2 $
#
# DATED:       $Date: 2009-07-28 16:53:52 $
#
# AUTHOR:      James Hagues
#
# DESCRIPTION: Config file for config628 - kChampion MX-01i-L

The config files are different eg in the keymap section:
854 has:
Keymap: r2c0 REPLY
Keymap: r2c1 BACK
Keymap: r2c2 SELECT
Keymap: r2c3 AUDIO_SOURCE

628 has:
Keymap: r2c0 AUDIO_SOURCE
Keymap: r2c1 BACK
Keymap: r2c2 REPLY
Keymap: r2c3 SELECT

there are some other differences in the "5dB boost" and "6db reduction" sections.

black007 reports that his radio's mainboard has the text "MX-01i-L/H<v2.0> "

I am sorry about mistake in my previous post. The correct file I need is config628.txt. Thank you for your help in advance.
