Si2168 B40 frimware.

Si2168 B40 frimware.

[Unembossed Name]

Hi,

Yesterday I extracted a new firmware for Si2168 B40 rev. from Windows 
driver.
It's designed for ROM version 4.0.2 and has a version build 4.0.19
Here is a name of 
file:dvb-demod-si2168-b40-rom4_0_2-patch-build4_0_19.fw.tar.gz
And a link for download: http://beholder.ru/bb/download/file.php?id=854
Anybody want to test it? Unfortunately, I can not do it myself, because I do 
not own hardware with B40 revision.

Best regards.

That does not even download. It looks like 17 byte chunk format, but it 
does not divide by 17. Probably there is some bytes missing or too many 
at the end of file.

That is how first 16 bytes of those firmwares looks:
4.0.4:  05 00 aa 4d 56 40 00 00  0c 6a 7e aa ef 51 da 89
4.0.11: 08 05 00 8d fc 56 40 00  00 00 00 00 00 00 00 00
4.0.19: 08 05 00 f0 9a 56 40 00  00 00 00 00 00 00 00 00

4.0.4 is 8 byte chunks, 4.0.11 is 17 byte.

Hi Antti,

You're right. I've made a mistake with determining of the end of a patch. It seems I  blindly used an obsolete information about 
size it should be. And because of that, these version of a patch can be even more recent. Like 4.0.20.

Could you please check it again? And in case of success see which version it is?

That one works, DVB-T/T2 scan tested.

Hi Antti,

Great! Thank you.
Instructions, on how to extract 4.0.19 for Si2168 B40 demod:
First, you have to download zipped file from http://beholder.ru/files/drv_v5510.zip
Unpack beholder.bin from it, and then use that command to extract firmware patch:
dd if=beholder.bin  bs=1 skip=69520 count=13651 of=dvb-demod-si2168-b40-rom4_0_2-patch-build4_0_19.fw

Best regards.

What's new with that firmware?
It's twice as big as 4.0.11, so there got to be a lot of changes and fixes.

I assume the info originates from 
http://beholder.ru/bb/viewtopic.php?f=11&t=14101 , but I don't understand 
Russian at all.

Hi Hurda,

I can't tell exactly what 4.0.19 does. May be I'm wrong, but I suppose, patch 4.0.19
for B40 has so big size, because most likely it resolves the same issues as patch 3.0.20 for A30:
Here, in Russia, TV broadcasters actively using Multi PLP in DVB-T2 transmissions.
In some cities, were problems with switching to PLP#1 or PLP#2 without A30 3.0.20 patch.
(Different cities in different time zones lead to a separate mux transport streams for them.)

What I can tell exactly, is that A30 3.0.20 contains an update for Si2168, which allows
demodulator to lock PLP#2 with an "old" type OFDM frame encoding. Also it speed up locking
for low bitrates PLP.
In short: it fixes a serious issue with Multi PLP locking.

Yes, you are right.
