Hi all,

 

I set up a system with imx6sl-evk + IMXEBOOKDC3 to test our own customerized E-Ink panel.

 

I know that how to replace the original 6.0" E-Ink display with 9.7" display, we need change the linux boot environment which is described in thread: connecting i.MX7D Sabre(MCIMX7SABRE) and E-INK panel(IMXEBOOKDC4)

"setenv mmcargs 'setenv bootargs console=${console},${baudrate} root=${mmcroot} epdc video=mxcepdcfb:E97_V110,bpp=16"

 

This makes sense because the "fb_videomode e97_v110_mode" struct is already defined in the mxc_epdc_fb.c driver.

 

However we now have a completely different customized panel, how to add its support and make the EPDC framebuffer driver unit test works with the new panel?

 

At moment is the new panel's waveform is not available, does this matter? Can I only modify the driver code to make unit test cover the new resolution of our panel?

 

Any detailed instruction would be very appreciated!

 

BR,

Jeff
