Thank You, guess i´ll give it a try, just want to avoid buying a screen and after that it dont work
If possible, kindly show your effort to us
so far no effort
I have tried VIM (latest Android Rom) together with IIYAMA ProLite T2435MSC-B2
touch didnt respons out of the box - as awaited
seems a bit difficult, at least for me. I found this page http://lii-enac.fr/en/architecture/linux-input/multitouch-devices.html
I have another (very old) touchscreen from 3M - I will try as soon as I have time to play
The latest Android Rom don’t support the hid touchscreen.
Are you a developer? If yes, you can follow below steps to build your rom supporting the hid touchscreen.
###Steps
- Config the kernel again
$ cd <your-path-to-project>
$ make -C common O=../out/target/product/kvim/obj/KERNEL_OBJ menuconfig ARCH=arm64 CROSS_COMPILE=$PREFIX_CROSS_COMPIL
-->Device Drivers
-->HID support
-->Special HID drivers
-->HID Multitouch panels
- Build your boot.img
$ source device/khadas/kvim/mkern.sh
-
Reflash the new boot.img
You can look here
If the hid touchscreen still not work, please provide the kernel log for me.
Thanks Terry, no, I am not a developer - just like to play, unfortunately dont have so much time for this and also too less knowledge about Linux & Android, but anyway, i will give it a try (Even a blind chicken finds a kernel of corn now and then)
Hello,
I have made the boot.img but on VIM2 I can’t load with tftp :
kvim2:/ # tftp 1080000 boot.img
BusyBox v1.26.2 bionic (2017-08-08 11:34 +0800) multi-call binary.
Usage: tftp [OPTIONS] HOST [PORT]
Transfer a file from/to tftp server
-l FILE Local FILE
-r FILE Remote FILE
-g Get file
-p Put file
kvim2:/ # bootm
tmp-mksh: bootm: not found
127|kvim2:/ # id
uid=0(root) gid=0(root) groups=0(root) context=u:r:init:s0
You need to enter uboot command mode to execute that command
- Connect uart port of VIM2 with PC via USB-TTL
- Focus on the serial terminal
- Long press the Enter button of your PC and don’t release
- Short Press the reset button of VIM2
Great !! Thank you
But with HID touch panels activated, the touchscreen doesn’t work.
Did you load boot image with TFTP and boot it with bootm command? It is not active after rebooting your device.
Can you provide the printing log for me ?
Hello,
Yes, from fresh install (Nougat). After I have installed the boot.img from TFTP and apply with bootm.
My SD card is dead … can I apply update.img with TFTP ?
I will test a new install and provide to you the logs.
I have a Vim2, is it the same command that Vim to build update.img and boot.img ?
It doesn’t support for loading update image with TFTP because the uart speed is too low and the update image is too larger.
You can flash update image with this.
It is the same command to load boot image and don’t support for loading update image.
Thanks.
Hello,
What I did it :
- Install update.img from VIM2_Nougat_V170831.
- Build Android from source (followed this http://docs.khadas.com/develop/BuildAndroid/)
- Config the kernel with HID Multitouch panels
- followed this http://docs.khadas.com/develop/LoadImagesWithUBootViaTFTP/#bootimg
My logs available here : https://pastebin.com/jqknLGWt
All android are used with a touch screen, why not activate it by default ?
Regards,
I can’t get the information of HID Multitouch panels. I only saw the USB Video (cx231xx) information.
Did you make sure the HID Multitouch panels config was enabled ?
What’s the mode of your HID Multitouch panels?
Yes, you are right. We will add support for it by default in next release ROM
Thanks.
Great news
I have checked if the module hid_multitouch was present in /sys/module/ and no … so I think I wrong thing
I’m trying again
Regards,
Hello @Terry,
I have not been able to advance…
Do you have an approximate date for the next version with the touchscreen management ?
Regards,
We will release new ROM for VIM2 at the end of this month. It will support for HID Multitouch panels.
Thanks
Very good news.
Thank you very much for your response
Hello,
It’s OK with UBoot VIM2_Uboot_Nougat_171023 and Android firmware VIM2_Nougat_vTV_V171024.
Thank you
Hi,
Could you suggest touch screen compatible with Vim?
n0n3Mpty, which one do you use?
