Hi,
sorry for hopping onto this thread, but I am experiencing the same problem with a WIMAXIT 7" Touchscreen (1024X600IPS). I suppose it's the same hardware.
Same symptoms, i.e.:
- touch function works out-of-the-box with Raspbian Buster
- Jivelite works ok with an attached USB mouse
- tc_calibrate fails with:

Code:

xres = 1024, yres = 600
Took 1 samples...
Top left : X = 1024 Y = 600
Took 1 samples...
Top right : X = 1024 Y = 600
Took 1 samples...
Bot right : X = 1024 Y = 600
Took 1 samples...
Bot left : X = 1024 Y = 600
Took 1 samples...
Center : X = 1024 Y = 600
ts_calibrate: determinant is too small -- 0.000000
Calibration failed.

As far as I observe, the lower right corner of the screen is responsive to touching. The vendor states that you have to add the following to config.txt (what I did):

Code:

hdmi_force_edid_audio=1
max_usb_current=1
hdmi_force_hotplug=1
config_hdmi_boost=7
hdmi_group=2
hdmi_mode=87
hdmi_drive=2
display_rotate=0
hdmi_cvt 1024 600 60 6 0 0 0

I've tried all the work-arounds I could find on the web - there seem to be more people with this problem, all of them only with piCore/tinycore/PCP.
So I'm very interested in a possible solution, as the screen seems really great.
Best regards
Martin

I don’t see a touch kernel module loaded. Can you boot your system, then plug in the touch cable……then post the tail end of dmesg.

Sorry Paul,
possibly I did before something wrong, did you mean vc_sm_cma 32768?

So it is just USB HID device. Should be cut and dry. Pretty sure that is similar to a 10.1 IPS screen that I have. Not sure I ever ran with jivelite on that screen.....but I'll take a look

Unfortunately, I'm getting ready to head out of town for a few days. But when I get back, I will.

So it is just USB HID device. Should be cut and dry. Pretty sure that is similar to a 10.1 IPS screen that I have. Not sure I ever ran with jivelite on that screen.....but I'll take a look

Unfortunately, I'm getting ready to head out of town for a few days. But when I get back, I will.

No hurry, thanks for caring

Should be cut and dry - glad to hear it! Thanks in advance.

My screen is a 10.1 1280x800 screen, I had no problems using at 1280x800 or 800x480 (Both resolutions have a good skin available). It is using a USB touch interface, but a different brand

Code:

[ 4.293828] usb 1-1.1.3: New USB device found, idVendor=0416, idProduct=c168, bcdDevice= 0.00
[ 4.293889] usb 1-1.1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 4.293933] usb 1-1.1.3: Product: MTouch
[ 4.293965] usb 1-1.1.3: Manufacturer: TSTP

This is on a pi3b+, running pCP 8.2

This is the added stuff to config.txt. Make sure to set both frame buffer size and hdmi size. No problems with ts_calibrate or test. No modifications to tslib.conf

Code:

framebuffer_width=800
framebuffer_height=480
dtoverlay=vc4-kms-v3d,audio
hdmi_cvt=800 480 60 6
hdmi_group=2
hdmi_mode=87
hdmi_drive=2

I'll have to reconfigure with a pi4 to see if there are any differences.

On the pi4, its a bit trickier, in that you have to also tell jivelite to what resolution you want. Set it on the tweaks page. Then edit your config.

But it worked fine at 800x480 and 1280x800

Code:

framebuffer_width=800
framebuffer_height=480
dtoverlay=vc4-kms-v3d-pi4,audio
hdmi_cvt=800 480 60 6
hdmi_group=2
hdmi_mode=87
hdmi_drive=2

Code:

framebuffer_width=1280
framebuffer_height=800
dtoverlay=vc4-kms-v3d-pi4,audio
hdmi_cvt=1280 800 60 5
hdmi_group=2
hdmi_mode=87
hdmi_drive=2

When running ts_calibrate run fbset to verify the correct resolution is shown. When using the 1280x800 resolution it wanted to run in 800x600 mode. As long as your config.txt is set correctly, then use

Code:

sudo fbset -xres xxxx -yres yyyy

to set the resolution before running ts_calibrate

PS, if your are not using HDMI audio, I would probably change to noaudio when loading the vc4 driver. Also, you should check your cvt data against tables on the rpi pages to make sure they are valid. If you don't use a valid setting, the pi4 will ignore your values. https://www.raspberrypi.com/document...#video-options

Many thanks Paul! Now it‘s me who is away from home. I‘ll try your suggestions asap.
Best regards

I've just tried with the display attached to a Pi3 with with the setting you've suggested. Same result as before:

Code:

tc@pCP:~$ sudo TSLIB_FBDEVICE=/dev/fb0 TSLIB_TSDEVICE=/dev/input/event0 /usr/loc
al/bin/ts_calibrate
xres = 800, yres = 480
Took 1 samples...
Top left : X = 1024 Y =  600
Took 1 samples...
Top right : X = 1024 Y =  600
Took 1 samples...
Bot right : X = 1024 Y =  600
Took 1 samples...
Bot left : X = 1024 Y =  600
Took 1 samples...
Center : X = 1024 Y =  600
ts_calibrate: determinant is too small -- 0.000000
Calibration failed.

Here is my config.txt:

Comment out these two lines. The vc4 driver has audio control, but probably not affecting anything.
#dtparam=audio=on
#audio_pwm_mode=2

What is the output of typing "fbset" just before you would run ts_calibrate.

Then when you run ts_calibrate, do the squares show up in the 4 corners of the screen and the direct center for the 5th point.

ok

Code:

tc@pCP:~$ fbset

mode "800x480-0"
        # D: 0.000 MHz, H: 0.000 kHz, V: 0.000 Hz
        geometry 800 480 800 480 16
        timings 0 0 0 0 0 0 0
        accel true
        rgba 5/11,6/5,5/0,0/0
endmode

Then when you run ts_calibrate, do the squares show up in the 4 corners of the screen and the direct center for the 5th point.

They do.
