Support connect LCD dispaly to iMX 6

[shai_b]

Hello team,

My customer needs your support starting communication between iMX 6 MPU and LCD display 4DLCD-28320240-[RTP] that uses ili9341v driver.

Today they are working iMX SoM VisionCB-6ULL-STD EVB. 

It seems that they need to add ili9341v driver in the Linux kernel (Debian 10 OS) and to change the device tree - and but they not sure how to do this?

Also, they need to adapt wires of mentioned above LCD to TFT LCD connector in EVB - How to connect correctly?

in the below links you can find the datasheet of LCD & EVB

EVB - https://somlabs.com/wp-content/uploads/VisionCB-STD-Datasheet-and-Pinout-v1-0.pdf

LCD - http://4dlcd.com/specs/4DLCD-28320240-Spec-V1.0-update%202018-07-10.pdf

Could you please advise/guide us on how to perform this action?

Your supports are highly appreciated.

Thanks in advance

Kind regards,

Shai

Hi Shai

for lcd connections one can look at Table 32-3. Pin use in MPU Mode

i.MX 6UltraLite Applications Processor Reference Manual

as for software one can look at below patch (no need for ili9341v driver as it

already provides mpu interface for that lcd):

Patch to support MPU 8080 LCD on iMX6UL and iMX7D 

Best regards
