Is it possible to use the MCIMX23LCD LCD display from the i.MX23-EVK into the i.MX28-EVK board?

Hi,

I want to use the MCIMX23LCD LCD display from the i.MX23-EVK board into the i.MX28-EVK board.

I noticed that the display driver for this LCD is present into the BSP of the i.MX28-EVK (BSP_10_08_02), located at
PLATFORM\iMX28-EVK-PDK1_9\SRC\DRIVERS\DISPLAY\lms430.cpp.

What is the procedure to build an NK.bin that makes use of this driver instead of the PLATFORM\iMX28-EVK-PDK1_9\SRC\DRIVERS\DISPLAY\43wvf1g.cpp driver?

Is it necessary to do some changes into the EBOOT also in order to support this LCD display?

Thanks in advance,

Ismael Infante

Hi Ismael,

Both LCD connectors have almost the same pin-out, unfortunately, there are a few differences that will make the systems not fully compatible, plus, the MX23 LCD is a WQVGA, and the MX28 LCD is a WVGA, so this may result in the need for SW changes too. So the answer is: You can't just connect the MX23 LCD into the MX28 without a few changes in HW and SW. You can check the differences between the connectors in the schematics found in the web page. I'm not a SW guy but I guess looking at the driver in the BSP can tell you what you need in that area too.

Best regards.

Jorge.
