4.16-rc5 on Motorola Droid 4

Hi!

I have the phone, I have safestrap installed, kexec seems to work (crashes my system). But I can't get any output from the new kernel.

All the howtos assume serial connection, but I don't yet have that. I'm really bad at soldering. IIRC display should work in the latest kernels, maybe with some patches?

Could someone give me .config and git hash that works for him? Once I get working display I should be able to continue easily. I'd really like to get voice calls working...

I took a brief look through dts, and I did not find anything that could be easily used for debugging. (It seems that capslock LED and keyboard backlight is not yet supported? Also volume down seems to be supported but not volume up, funny).

Best regards,
Pavel

Yeah display related stuff is half merged in Linux next, backlight needs some binding changes from what I remember. I think the minimal set is something like this against v4.16-rc:

backlight: add TI LMU backlight driver drm/omap: add framedone interrupt support drm/omap: add manual update detection helper drm/omap: add support for manually updated displays

Then also audio support is also half merged and need few patches if you check the mailing list archives for cpcap codec related patches.

Maybe get somebody to help you locally with the debug cable soldering? :)

You want to use omapdrm, below is what I'm using with loadable modules with Linux next based on omap2plus_defconfig. It has some extra debug options enabled too that you might want to ignore, I'll try to send the defconfig related patches out too.

Basically you need the CONFIG_MFD_TI_LMU, CONFIG_DRM_OMAP and CONFIG_DRM_OMAP_PANEL_DSI_CM related options.

Oh I thought we had all the LEDs mapped already? Volume down is on the internal keypad, then volume up is on a GPIO controller. I guess to allow chords for the bootloader.

Regards,

Tony

Hi,

I have an updated lm355x backlight driver almost ready, that uses an updated binding scheme and exposes the keyboard backlight using the LED subsystem.

I just noticed, that I missed Rob gave his Acked-by to the binding already. I will prepare a PATCHv6 with the MFD changes this week.

I suppose people from your hackerspace can help you. It's really easy to do. Soldering can be avoided btw. You can just use a pair of scissors to cut a USB -> Micro USB cable and use a knife to remove isolation. Then screw each of the 4 wires into a terminal strip. There are USB-TTL adapters available, that have an attached cable. If you also cut the connector from such a cable and connect it to the other side of the terminal strip you are done. No soldering involved ;)

The keyboard backlight and lcd backlight are controlled by LM3552, that's the driver mentioned above. The other LEDs (status rgb, shift/capslock, and the android button backlight) are working.

Hi!

Hehe. After some more experiments, it looks like hardware hacking can not be avoided :-(.

I should have enough connectors, but I don't know the pinouts. I also seem to have D-SUN USB to TTL from you (thanks again!).

You say TTL, Tony says 3V3... so I guess the port can survive both?

Ok, I guess I really only need to connect GND, and then D- to RXD?

So... where is the D-.. aha, got it. I hope USB has to be robust enough against me making experiments?

I connected it the best way I could, but I do not get data in minicom, and RXD led stays lit. I guess that is not a good thing :-(.

Hi!

Hm. How big no-no is connecting USB-TTL adapter to D+/D- pins? Because that's what I could do "easily" and seems to work ;-).

Well if the VBUS line is not connected the PMIC is muxed to USB carkit mode so the lines go to the UART on the SoC through some level shifter. If it works it should not cause any issues, the symptoms I saw earlier was corrupted UART console and noticed that what worked best for me was 3.3V ftdi based devices out of the collection of random pl2303 and ftdi cables I had around.

I guess somebody could try to measure the uart lines with a scope with nothing connected and sending out data from droid 4. Or look at the carkit spec for the UART voltage levels.

Regards,

Tony

So.. I do have some fun on the UART (^@ inserted).

Voltmeter says Droid4 transmits at 3.3V.

Anyway, it now works for me well enough that I can attempt to debug the .config file :-).

Hi!

If I could get a diff, I'd happily test it :-).

Also, if you know how to get information from light sensor, that would be nice.

Confirmed. They work, and they have reasonable names.

Thanks,
Pavel

Hi,

You need CONFIG_SENSORS_ISL29028. Once the driver is probed:

$ cat /sys/bus/iio/devices/iio\:device1/name
isl29030
$ cat /sys/bus/iio/devices/iio\:device1/in_illuminance_input
19

Thanks, that works.

I was also able to get accelerometers to work, but they are extremely slow to read (6 seconds for all 3 axis). Interesting, but probably not too important for now.

Best regards,
Pavel

Hi,

IIRC this is related to runtime PM. It should not be a problem if you use libiio.
