[youling257]

my tablet onda v891w，8.9 inch，copy this /lib/modules/gslx68x_ts.ko ，isn't system/vendor/modules/，tools/fw_extractor gslx68x_ts.ko firmware.fw，not success，https://drive.google.com/open?id=0B1HDhURlGNctM3hxSF8xTE55aDA ，modules，can you help me extract firmware.fw ?

[onitake]

Umm... No success?

I get this:

All the GSLX680_FW* files look like proper firmware files. To find out which one to use, check which chip you have (you may have to open the device), then test the matching ones. The I89 may hint to the panel size, so try those first, perhaps.

[onitake]

Aaah, now I see your problem. The documentation is wrong. Sorry. Will fix that in a moment.

[onitake]

Documentation fix applied in 537bf55639942f94d066078c3db15fec146955c1.

./fwtool -c FW_I89_GSL3676B19201200.fw -w 1920 -h 1200 -t 10 silead_ts.fw，it is correct ？ developer options，show touches，show visual feedback for touches，enable，the finger click position, touchscreen White dot ，Offset to the right，to the right side，why?

but i use chuwi hi8 's firmware.fw，convert silead_ts.fw，the finger click position, touchscreen White dot ，Offset to the left，why? it's not calibration problem，can't calibration touchscreen

please see here， https://sourceforge.net/p/android-x86/kernel/ci/3f1bd4aea203b8a1f279da53c9c24bb00df5badc/

[onitake]

I can't tell you if it's correct. I don't know the exact specs of your device. You need to test and find them out yourself.

Offsets or inaccessible areas are probably caused by incorrect touchscreen dimensions. These can be different from the display resolution. There is currently no reliable way to determine them, you need to do some experimentation.

If calibration using xinput_calibrator is not an option, then you need to set the correct parameters in the firmware. Use xinput test <device number> (find the number with xinput list) to see the all touch events, then move your finger around the corners a bit. This should give you an idea what the dimensions of the touchscreen are. Set those using fwtool -w <width> -h <height>.

If you don't get multitouch events, or if the axes seem to be swapped or mirrored, set the corresponding parameters using fwtool -f.

[youling257]

oh，no，i don't know how to do，-m -w -h ，correct parameters，oh ，no，i don't know

[onitake]

As I said, some experimentation is necessary.

Convert the firmware using default parameters, then test using xinput test. Once you've found out the approximate width and height of the the touch panel, set those parameters using fwtool -w <width> -h <height>. If you encounter any problems like a mirrored axis or broken multitouch, set the appropriate flag using fwtool -f <flag>.

I'm sorry if I can't help you any further.

[youling257]

how to use fwtool -f ? please example

[onitake]

Let's say your touchscreen is mirrored on the horizontal axis, i.e. when you touch on the left, it registers on the right and vice-versa. In this case, you would use: fwtool -f xflip

Or, you notice that multitouch does not work. In this case, you can try enabling finger tracking: fwtool -f track

If you want to combine the options, separate them by a comma: fwtool -f xflip,track

[onitake]

The other options are:

-f    Sets flags, separated by commas (optional, supported flags: xflip, yflip, swap, track)
      xflip enables horizontal flipping
      yflip enables vertical flipping
      swap enables axis swapping
      track enables in-driver finger tracking (use for controllers that don't support it)
      Each flag may be prefixed with 'no' to disable it.

[youling257]

Up and down，Upside down ; left right，not Upside down. how to fix ? I can't speak english，I do not proficient linux，you say fwtool -f and more，Please tell me for each terminal command，i only can install Ubuntu and Androidx86 on my tablet

[onitake]

Ok, I think I'm beginning to understand what your problem is. You seem to be experiencing a mirrored y axis.

Try this:

./fwtool -c FW_I89_GSL3676B_19201200_.fw -w 1920 -h 1200 -t 10 -f yflip silead_ts.fw
sudo cp silead_ts.fw /lib/firmware

Do you also need help with the driver installation?

[youling257]

I know modprobe -r gslx680_ts_acpi，modprobe gslx680_ts_acpi

[onitake]

Ah, very good.

So, just create silead_ts.fw, copy to /lib/firmware, and you should be good to go. If it doesn't work, try the same procedure with the other firmwares.

[youling257]

ok，already vertical flipping，but -w -h parameter still incorrect，i can't understand xinput test result.

oh，yes，-w 1920 -h 1200 -f yflip ，correct parameter，when vertical flipping later，then use calibrate touchscreen calibration，click Precision，nice

[youling257]

not perfect，click not Precision . I do these，in order to on Android x86 6.0.1，use touchscreen，still has problem，already use calibration app ，Quick Settings drop-down and Side slide，can't do this in order to use touchscreen do these，http://i.imgur.com/fcUALEc.png http://i.imgur.com/oKPQBWr.png

on Android x86 6.0.1，only 1 point，not 10 point，already fwtool -t 10，why ? on Ubuntu ，i don't know how many point on Android x86 6.0.1，has Small offset

[youling257]

This is Android x86 6.0.1，http://i.imgur.com/ZDq4PKB.png http://i.imgur.com/fcUALEc.png This is dual os 4.4.4，http://i.imgur.com/hBrmVNi.png http://i.imgur.com/KMdpGyL.png

[onitake]

Nice, at least there's some progress.

xinput test will print the coordinates of all input events. If you move your finger across the screen, especially around the edges, you will see the maxima for the pixel coordinates. That way, you should be able to determine the accurate values for -w and -h.

I don't have a working test device right now, so I can't provide you with example output. But I'll post here when I have some.

[youling257]

can't find correct parameters，it must be -w 1920 -h 1200，because “This is Android x86 6.0.1，http://i.imgur.com/ZDq4PKB.png http://i.imgur.com/fcUALEc.png This is dual os 4.4.4，http://i.imgur.com/hBrmVNi.png http://i.imgur.com/KMdpGyL.png ” whatever i do ，every time boot Ubuntu，must calibration touchscreen every time boot Androidx86 6.0.1，also need calibration touchscreen，but it can't，can't calibration

[youling257]

oh，no，The left side，not offset，the finger from left side to right side，offset bigger and bigger

[onitake]

If you have an offset or scaling Problem, then the -w 1920 -h 1200 is most likely NOT correct.

Try smaller values, like -w 1024 -h 600 for example. Or test using xinput test as I described above to determine the correct values.

[youling257]

i find my tablet SileadTouch.fw，I890_3676B_19201200_PG_WJ_WJ888_Drivers-20150604.zip，then ./fwtool -c SileadTouch.fw -3 -w 1920 -h 1200 -t 10 silead_ts.fw， Up and down，Upside down ; left right，also Upside down；how to do ? -w 1920 -h 1200 -f yflip xclip ?what terminal command ?

[onitake]

To enable both horizontal and vertical mirroring, use this: ./fwtool -c SileadTouch.fw -3 -w 1920 -h 1200 -t 10 -f xflip,yflip silead_ts.fw

[youling257]

This SileadTouch.fw has more problem，Not as good as FW_I89_GSL3676B19201200.fw when xflip yflip later，I can only describe，Sliding screen on the left ， display on the right ，Sliding screen on the right , display on the left . ok，Still study FW_I89_GSL3676B19201200.fw

[youling257]

FW_I89_GSL3676B19201200.fw，no matter what parameters，Before calibration， xinput test ， top left corner ，a[0]=20，bottom left corner ，a[0]=40 use xinput，only can get probably parameters，Inaccurate, imprecise，This is not enough；you know，The touch screen on Androidx86 is must be more accurate than the mouse，must Precise and accurate parameters，can't get. I say，can't do this ，http://i.imgur.com/oKPQBWr.png ，because parameters is Inaccurate ，imprecise

[onitake]

Hmm I see... But that could just mean that the firmware does not work with your chip.

Can you open your device and check if you really have a GSL3676B?

[youling257]

what mean ? extract gslx68x_ts.ko，get GSL3676B firmware，gslx68x_ts.ko from onda v891w dual-os Android 4.4.4，what mean “open your device” ?

[onitake]

I mean, you should disassemble your tablet physically and look inside what chips you have on the circuit board. Check which Silead chip you have exactly (GSL3676B, GSL2681, GSL1680, ....) to make sure you use the correct firmware.

[youling257]

yes，onda v891w，gsl 3676，Disassemble is my hobby，Just bought，first to do disassemble like this， http://i3.bbs.fd.zol-img.com.cn/t_s800x5000/g2/M00/0E/04/Cg-4WVWuCTqISLsCAAIWZNEp7FUAAHclAOOEHwAAhZ8023.jpg http://bbs.zol.com.cn/quanzi/d26_795_uid_a757338903.html

also like this，http://bbs.mydigit.cn/read.php?tid=1107465

[onitake]

Ok, ok. Very good! :)

If you use the wrong firmware for the chip, you will get very strange results. Inaccuracy is normal, however. The chip sends out touch events without much interpolation, and gslx680-acpi doesn't interpolate either. I know that this leads to all kinds of problems, but I assumed that user space would handle this better. Unfortunately, that's not the case.

My test environment is Ubuntu 15.10, where basic stuff like touching buttons and typing work more or less, but dragging is a big problem, and I had lots of reliability problems close to the edges.

Unfortunately, I don't know a good way to solve these.

If you need a quicker solution, better try this driver here: https://github.com/rastersoft/gsl1680 It uses the FW_I89_GSL3676B19201200.fw firmware directly (no need to convert with fwtool), but runs in user space and requires some manual setup for the GPIO pins.

[onitake]

Found <n> offset <x> count <y>

That means it found a firmware image at file offset <x>, of length <y> bytes. The firmware will then be written out to <n>.fw.

[youling257]

Found FW_I89_GSL3676B19201200 offset 455296 count 40392， ./fwtool -c FW_I89_GSL3676B19201200.fw -w ？ -h ？，Is there any relationship between the two?

[onitake]

I don't know, really.

The only known fact is that the limit for -w and -h is 4095, because they're 12 bit values. Other than that - unknown...

[youling257]

https://github.com/sigboe/gslX68X ， “You will need to place a firmware file at /lib/firmware/[hid].fw where you replace [hid] with the HID ID of your device.” ，I can't understand

[onitake]

Yes, that part is a bit unfortunate. [HID] is the ACPI or DT ID of the device. In most cases, this is mssl1680, but you'll have to check.

See my comment on https://github.com/sigboe/gslX68X/issues/3 for more info.

[youling257]

gslx680_ts_acpi.ko，need silead_ts.fw ; silead.ko need what fw ?

[onitake]

Please don't mix up the drivers.

gslx680_ts_acpi.ko (from gslx680-acpi) needs silead_ts.fw created with fwtool.

silead.ko (from gslX68X) needs the firmware directly as it comes out of fw_extractor, and you need to rename it to [hid].fw, where [hid] is usually mssl1680. If mssl1680.fw does not work, look at the dmesg output. It will tell you which file it's expecting.

[youling257]

https://github.com/rastersoft/gsl1680 ，how to launch the driver ?

gslx680_ts_acpi.ko and silead_ts.fw，only one point，can't Multi-touch；OK，I don't ask for more，Then basic Double finger zoom，I want this.

[barni2000]

If only touch it at one point, then need track flag when you are generating firmware for gslx680_ts_acpi.ko.

[holzingerm]

as superuser (linux normally sudo or su)

modprobe gslx680_ts_acpi

if the module is installed correctly than it would load during our discussion on android-x86 i would say you shall open the terminal app type in su to get super user permissions and type in the command (modprobe....)

tanks for the tip with flag to get multitouch working will try it also on my side

regards Mario

[youling257]

barni2000 ，please tell me Terminal Command

[barni2000]

fwtool

[youling257]

I can't speak english，I do not proficient linux，you say fwtool more，Please tell me for each terminal command，i only can install Ubuntu and Androidx86 on my tablet，，barni2000

[holzingerm]

Linux: sudo modprobe gslx680_ts_acpi

Android: terminal app su modprobe gslx680_ts_acpi

[youling257]

holzingerm ， I know who are you，The basic load drive command, I knew ；now the problem，Double finger zoom，xposed GravityBox [MM] pie control……

[barni2000]

Something like this: ./fwtool -c SileadTouch.fw -3 -w 1920 -h 1200 -t 10 -f xflip,yflip,track silead_ts.fw

[holzingerm]

is the -3 really correct?? i try to help youling257 but with android drivers I need to convert the android drivers like

./fwtool -c GSLX680_FW_I81_GSL3676B_8.fw -1 -m 3676 -h 1920 -w 1200 -t 10 -f xflip,yflip,track silead_ts.fw

to get a valid output

[barni2000]

i just copy paste an comment from above and write to flags the track

[youling257]

use xinput，only can get probably parameters，Inaccurate, imprecise，This is not enough；you know，The touch screen on Androidx86 is must be more accurate than the mouse，must Precise and accurate parameters，can't get. I say，can't do this ，http://i.imgur.com/oKPQBWr.png ，because parameters is Inaccurate ，imprecise

i can tell your these，repeat
