Afatech 9015 USB DVB-T driver no longer included

[vondrt4]

Hi! When updating from kernel 4.16 to 4.19, my TV stick stopped working. The modules have probably not been built. I had to rollback to the last SD card backup (Thanks for that feature!). Was that a glitch or is it intentional?

[mkreisl]

I can't tell you what happened exactly. That modules was lost with kernel 4.18. No idea why because procedure upgrading to next kernel version is always the same.

Anyway, will enabling this module again for the next next 4.19 kernel release (probably 4.19.70+)

[mkreisl]

@vondrt4 FYI: Kernel 4.19.72+ should have this module included again

[vondrt4]

Sorry, but it's still not there. Looked in 4.19.72+, 4.19.75+, and 4.19.80+.

[mkreisl]

You're confusing me.

Which module are you missing? dvb-usb-af9015.ko should be available in kernel packages now, I have checked this https://cateee.net/lkddb/web-lkddb/DVB_USB_AF9015.html

[vondrt4]

Yes, that should be it. And it is not present in http://apt.xbian.org/pool/stable/rpi-stretch/x/xbian-package-kernel/ or http://apt.xbian.org/pool/stable/rpi-buster/x/xbian-package-kernel/.

[vondrt4]

I have downloaded the kernel sources and your .config and ran "make menuconfig" and it didn't let me select AF9015 until I also selected I2C_MUX, which is listed as dependency. I'll try compiling on the RPi, maybe you'll be faster...

[mkreisl]

Sorry, but I can't follow you.

I've downloaded latest kernel for Pi2 (Debian Stretch, stable repo), and looked into: the module is there!

And you can see, module dvb-usb-af9015.ko is in this package

[vondrt4]

There seems to be a difference between the RPi and RPi2 versions. # CONFIG_I2C_MUX is not set for RPi and CONFIG_I2C_MUX = m for RPi2

Ok, that could be the reason. I assumed that you are using Pi2 or higher

So, have to fix this for Pi1 as well

[mkreisl]

New version 4.19.80 has been built for Pi1 with module for AF9015 included and is available for download in a few minutes

[vondrt4]

Hi! My poor Raspberry just finished compiling, but it already has the module loaded thanks to you.

You're welcome

Yeah, building kernel on a Pi1 is PITA :smile: I tried this 6 years ago once, but stopped it after more than 15hrs.
