Touchpad not working
Hi, I am testing the arch Linux xfce image and my touchpad does not work at all.
Any help would be nice.
Hi.
Not working at all.. may be you have different touchpad h/w.
I have try it and in my case only tapping/clicking doesn't work, but there is a simple solution for it.
I have the same issue. I dont even have anything showing up in the device box.
What did say cat /proc/bus/input/devices and xinput list?
In my case there are
cat /proc/bus/input/devices

Actually Atmel maXTouch (atmel_mxt_ts) should be compiled as kernel module and available to modprobe like sudo modprobe atmel_mxt_ts .
https://ww1.microchip.com/downloads/en/Appnotes/AN3084_Using_the_maXTouch_Linux_Driver_00003084A.pdf page 5 but I am not sure about dtsi files, exynos5 dtsi do not contain any Atmel maXTouch lines. And according to page 10 some firmware could be required.
Well heck, this seems a little out of my wheel house on linux knowledge. The old kali linux image I used by the way is kali-linux-2019.3-exynos.img.xz from http://old.kali.org/arm-images/kali-2019.3/ for future people if I cant figure this out.
So that mean modprobe didnt work.
probably i missed exynos5250-spring.dts, looks like it contain some maxtouch line. Probably original Kali scripts adds it to kernel during build system. And ChromeOs uses some maxtouch firmware.
For mount chromeos disk image i was use something like:
sudo mount -o,loop,offset=$((512*319488)),ro ./chromeos_recovery.bin mountfolder
and firmware symlinks lead to opt/google/firmware
Looks like you run void-linux. Solution may be in re-signing kernel with spring dtb file. Copy exynos5250-spring.dtb to /boot/dtb and run modded 10-flashkernel with sudo privileges; agree to re-sign and flash kernel. Be careful where to flash it in case you steel have chromeos. Re-signing kernel will require vboot-utils, uboot-tools, cgpt etc. I did not remember exact packages names and it installation status, so check it before re-signing
Actually dts provided with kernel source and may not work with different ver, but it is not like file itself changes from ver to ver so it may work with that dtb.
maxhouch fw and cfg may be copied to firmware dir in case dmesg gives maxtouch firmware load errors
everything runs fine up to dd: failed to open '/boot/kernel_image' no such file of directory. I went there and confirmed it is indeed not there. I was only trying void because I was going through your prebuilt images seeing if it worked on any of them. I had not actually ever heard of it before. I've only ever messed around with debian and arch distros before.
There are was changes in kernel package. That script taken from new ver, probably some incompatibilities. Ok, i will try to recompile kernel with extra dtb files.
Recompiled kernel void-glibc.zip void-musl.zip deb-arch.zip
deb package works as previous in my devuan system, for void should too. Arch-arm package could be repacked from deb.

spring dtb is included now, i hope that help
Trying the devuan image and after installing vboot-kernel-utils to resign the kernel after running the deb. It seems like even after it seems to have completed fine, it still does not work.
edit: Forgot to include after doing all of this cat /proc/bus/input/devices and xinput list still return nothing.
Does dmesg says somthing about maxtouch fw?
I did inspect old kali disk image that successfully detected your touchpad and find out it use old Chrome Os 3.8 kernel with blobs:
- exynos5250-skate.dtb
- exynos5250-smdk5250.dtb
- exynos5250-snow-rev4.dtb
- exynos5250-snow-rev5.dtb
- exynos5250-spring.dtb and other blobs for other CPUs.
skate and snow-rev4 are not available at newer kernel source.
I added smdk blob and recompiled it but not sure this will solve the problem. deb.zip
I grabbed kernel from that old kali, like:
dd if=kali-linux-2019.3-exynos.img of=kernel_image bs=512 skip=8192 count=32768 and dd kernel_image to kernel partition of devuan; copy /lib/modules/3.18* and firmwares. Then try to boot. It boots but stuck because btrfs unsupported. So i did backup all files from root partition, reformat it to ext2, restore files and mod /etc/fstab to correspond rootfs. It boots succesfully, but slover. I guess same true for archlinuxarm or any other armv7 (glibc) distro.
Old kernel config contain same maxtouch driver but it was specified as a part of kernel and not module.
Not that I could see from dmesg. I'll try your recompile later when I get a chance. This is the most stubborn hardware.

Log has link to wifi firmware only.
So now we know wich blob is used [ 0.000000] OF: fdt: Machine model: Google Snow Rev 5+ I guess touchpad config may be integrated to it.
In my case its [ 0.000000] OF: fdt: Machine model: Google Snow
I did make some changes in blobs source and recompile it again. Now dmesg shows something that was absent before:

wow that did something. It is showing up as the maXTouch Touchscreen. It works but it is acting as if it is a touch screen. So where you touch it the mouse goes there. Was there a flag for touchscreen vs touchpad? I'm amazed its even working. Very close
Edit: Have you seen these? https://github.com/atmel-maxtouch/maXTouch_linux https://www.kernel.org/doc/Documentation/devicetree/bindings/input/atmel%2Cmaxtouch.txt
I dont know if anything is of use here. I'm not super familiar with Kernel stuff.
Kernel driver itself is for touchscreens. Maybe chrome os firmware config reassigns it as a trackpad. Do you copied maxtouch.fw and maxtouch.cfg to /lib/firmware ?
I am not a C developer, i just writed by analogy to chromeos kernel 3.18. Patch:

I was not seen that. Thanks. I did change atmel_mxt_tp to maxtouch and recompile it. To try it you need to overwrite files at /boot/dtbs , re-sign kernel, re-flash kernel and reboot. exynos5250.zip
I started with a fresh image and reflashed and resigned with the new dtb files. I also placed the firmware files in /lib/firmware. However it still acts like the touchscreen and reports in dmesg as atmel_mxt_ts.

Making that driver detect device as a trackpad may require more diging in subject or maybe conculting with developers.
I find some example how to assign touchpad as touchscreen or something like that, guess it could be done in reverse. https://askubuntu.com/questions/822272/monitor-is-detecting-as-touchpad-instead-of-touchscreen https://unix.stackexchange.com/questions/129339/touchscreen-and-mouse-as-separate-inputs
edit: I changed dts in similar way to spring.dts but not sure about pinctrl-names and pinctrl-0 so it was commented. Added gpio-keymap and interrupt type changed to edge_falling. Patch is

I never got notified about the edit and decided to comeback and see if I missed a notification. Your changed dtb files did the trick. Tapping and clicking works. Even 2 finger scrolling. I also shows up as a touchpad in the system. Amazing work, thank you for taking the time to figure out the issue with this very old and outdated Chromebook. Now I just need to look into getting it to run on the internal emmc. Any leads where I could start looking for that. I've seen a couple sketchy guides but don't want to nuke this laptop. I don't know how tied in the CTRL+U boot loader is tied into the partitions of the EMMC.
Edit: ok starting from a fresh image here is what I did to getting it working. First I install vboot-kernel-utils. I then run the file .deb file located in deb_pkg.zip. I tried doing it without this deb file but I suspect it contains the spring.dts file and it is needed. Then I copy over the config and firmware files from the maxtouch.zip to lib/firmware. Then from the latest dtb.zip i copy those to boot/dtbs and then run the reflash in boot/reflash and say yes to both prompts. Then I restart and have a working touchpad.
I am glad it helped.
With my model it is possible to brick it in case of removing chrome os, exiting from dev mode and rebooting in same time. So my suggestion is do not exit from dev mode until you may succesfully boot from emmc. Disconnecting battery or complete discharge leads to exiting from dev mode too.
Guide actually same for emmc as for usb or sd-card (micro-sd-card + sd adapter), diffs only on specified device. Usually /dev/sda is a usb, /dev/mmcblk1 - sd-card and /dev/mmcblk0 - emmc (partitions like /dev/mmcblk0p1 and so on). You may manually repart it like described on archlinuxarm guide. Be aware, on step 7 of that guide should be used apostrophes and not quotes. It has different meaning for shell. At first time i was stuck there. Or you may use edim script to create disk image with same size as emmc, write there rootfs and kernel than dd disk image to emmc. Demonstartion of using edim script on main page of this project. In my case emmc size is 15028M. edim script creates only kernel and rootfs partitions. With manual method you may add swap partition or use another sheme (i suggest to try it on usb or sdcard firstly). Partitioning with anything other than cgpt with hight chance will lead to unbootable system.
To boot from emmc at dev mode you need to press Ctrl+D
As I know there is another method with flashing unverified uboot, in that case it does not matter wich util you use for patitioning disk.. but i never tryed it.
edit: Actually in the last kernel deb i returned to previous scheme without spring.dtb because of trying to integrate atmel trackpad support to snow and snow-rev5 dtbs
Awesome thank you for all the help. I went ahead and compiled everything together and edited the deb and wrapped it up in a little script. Figured I'd drop it here for anyone in the future.
FixTrackpadSamsungXE303C12.zip Just follow the readme and should be pretty dummy proof. Worked for me on a fresh image.
Now I just gotta look into putting it over chromium or somehow making the normal usb port look to the usb3 port to boot from a usb harddrive.
