I have a imx6sll-evk board and i try to connect the EBOOKDC4 to it. I have install the fsl-image-validation-imx-xwayland-imx6sllevk.sdcard from the L4.9.88_2.0.0_images_MX6SLLEVK linux file.


I can't perform the unit test EPDC unit test:

>"Unable to open /dev/fb2"


During the boot I have noticed that the I2C communication with the PMIC 17135 failed:

>"0-0048 supply SENSOR not found, using dummy regulator"

>"i2c i2c-0: Max17135 PMIC not found!"

>"imx_epdc_v2_fb 20f4000.epdc: Unable to get display PMIC regulator .err = 0xfffffdfb"


I have try to set the following env. variable, but it doesn't change anything.

epdc 'video=mxcepdcfb:ED060XH2C1,bpp=16'


Do you have any idea how to fix it?


Best regards,
