[TBS6205] Problems downloading the firmware for the first time. #259

Closed MastaG closed 2 years ago

MastaG commented 2 years ago

Hi there,

I'm running Fedora 34 with the latest drivers. The card works, but it will give the following when TVHheadend starts:

I have to go into TV Adapters tab, deactivate and reactivate iets tuner, one by one, before they can successfully load the firmware and initialize. This is bit nasty because I have to do this after every reboot.

Could this be fixed?

OldAVman commented 2 years ago

Hi, I've recently updated the kernel and this driver in my htpc box. I use this driver as I have a TBS satellite card. I also have a Mygica T230 USB tuner for terrestrial TV. This uses the same Si2158 tuner chip as the OP's card and I'm suddenly seeing a similar problem. Typically, following power up the tuner will always load the firmware and correctly tune to the selected channel. If another channel is then selected it will nearly always fail to load the firmware and the 'firmware download failed -11' message will appear in dmesg. Selecting a channel again will then usually work. This fail, work, fail, work sequence then continues making channel selection very hit and miss. If the power is removed and then reinstated the tuner will always work first time. I'm now on kernel 5.14.14 and hadn't updated for some time but the tuner used to work reliably. I can't see anything in the driver that appears to have changed relevant to this particular chip and the firmware doesn't seem to have changed recently so I'm confused as to what's happened. I haven't made any hardware changes to my system. As the OP's card is PCIE and my tuner is USB the firmware loading code must be different so it seems strange we're both seeing a similar symptom. Anybody else seeing this and have any clues?

Same for me. I also have a few USB dvb sticks using the same tuner chip.

However with the TBS drivers, the card seems have trouble loading it's firmware for the first time. Perhaps a hack can be added to TV-headend to set some random delay between 1 and 4 seconds before initializing each tuner.

Hi, I don't use TVHheadend myself, I use my own tuner software (based on V4L code) and your problem sounds a little different. For me the firmware download always works first time but fails on alternate channel selections. I've always found the firmware download a bit unreliable for the si2157. After looking through the relevant code I seem to have found a solution which works for me at least. I've never really understood why the firmware has to be repeatedly loaded into the chip, I'm assuming it's stored in non volatile memory and once programmed in should remain intact through power cycles etc. Looking in /media_build/linux/drivers/media/tuners/si2157.h I noticed the struct si2157_config has a member 'dont_load_firmware' which is indeed set to true in a couple of the drivers that use this chip. My dvb stick is handled by the dvbsky driver in /media/drivers/media/usb/dvb-usb-v2/ so I inserted a line 'si2157_config.dont_load_firmware = true' in the dvbsky.c file at line 560 where another member of the struct is initialised. After re-compiling this seems to have worked. The driver no longer attempts to reload the firmware each time the tuner is used and the channels all now select reliably every time. This (highly unofficial) solution of course depends on the firmware having been correctly loaded into the stick at some point in its life, but as far as I can see this should only need to be done once. (if this is incorrect someone please enlighten me!) This bodge has worked for me on three sticks for over a week now through multiple plugs/unplugs. If you find the relevant .c file for your tuner you may be able to try something similar.

Silabs tuner/demods have some on-chip MCU ROM with initial firmware, copied to MCU RAM on reset and possible load firmware patch on init.

OldAVman commented 2 years ago

Crazycat, Thanks for the information. The only datasheet I could find for the si2157 was a short form version which contained no useful operational details at all. I guess a proper datasheet is only available to manufacturers.

Crazycat, Thanks again, very useful, will read.
