Hi,
I am using i.MX7D Sabre(MCIMX7SABRE) with E-INK panel(X-IMXEBOOKDC4) to check the display, I have downloaded pre-build image: L4.1.15_2.0.0-ga_images_MX7DSABRESD.tar.gz with md5sum: 167fceda879c814280924b05c4e48317 located at download
used contents: fsl-image-validation-imx-x11-imx7d.sdcard; zImage; u-boot-imx7dsabresd_epdc.imx; zImage-imx7d-sdb-epdc.dtb
Using above setup I am able to get the EPDC display initialized well.
Even the validation with imx-lib as guided @ https://community.nxp.com/docs/DOC-328663 worked out of box.
Using mxc_epdc_v2_fb_test.out able to get the various unit tests executed well on display.
Moving further I would like to check E-INK panel(X-IMXEBOOKDC4) supported with Xserver and Touchscreen support?
1. Observed fsl-image-validation-imx-x11-imx7d.sdcard booting with OE banner then Xserver won't acquire the E-INK display. Also observed X11 imx-test for epdc was explicitly removed /unit_tests/mxc_epdc_x11_fb_test.out @ ref https://bugzilla.yoctoproject.org/show_bug.cgi?id=3615
apart from it I didn't found out particular X11 validation for epdc display,
is Xserver support available for E-INK panel(X-IMXEBOOKDC4) ?
2. Is E-INK panel(X-IMXEBOOKDC4) have touchscreen support?
3. any pointers on getting schematic/documents for E-INK panel(X-IMXEBOOKDC4)?
Please advise, sharing pointers or references if any will be a great help.
Thanks

Hi Shrikant,
For Touch issues please check:
https://community.nxp.com/message/919809
There are no special x11 unit tests, in unit_test one can find test sources which can be used for custom testing or developing new drivers. xserver for MX7 run on xf86-config, please check your BSP recipes-graphics/xorg-xserver/.
Also check how to verify the EPDC functionality:
How to verify EPD panel functionality
To get the X-IMXEBOOKDC4 schematic, under NDA you migth have to apply to your local FAE.
Hope it helps
Thanks! @Bio_TICFSL for providing the details, I am going through it & I will get back with further difficulties/queries if any.
Thanks

Hi Bio_TICFSL
Please have a look, I have tried with my BSP specific xf86-config
But didn't got xserver running.
For elan-touch: I am also facing similar error @ elan touch driver error
Please advise!
Thanks

Hi ShrikantBobade,
Did you test the Xserver in EPDC ?
If Yes, can you post how you solved the issues ?
Thanks
