Porting driver

[phamhuynh]

good day for everybody, i'm porting driver for display of Mirasol, i use iMX6SL EVK, and display:

- Module display Mirasol Chocolate RGB 1.5" 288x192

- Driver IC Display: PA6561A2

- Interface: MIPI DBI 8 bit parrallel, 3/4-wire SPI.

Who have driver for this display, or have ported driver for this display?? can help me for driver, i need driver for this module display

thank for view!

Please use the recent (Yocto) Linux BSP for the i.MX6 EVK.

Summary Page :

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=IMX6_SW

The most simple way to start - to use demo image :

$ sudo dd if= fsl-image-x11-imx6slevk.sdcard of=/dev/sdb bs=1M

Please look at the following for some details.

"Task #4 - Deploy and test"

https://community.freescale.com/docs/DOC-94989

Next, You may refer to Chapter 7 (MIPI DSI Driver) of “i.MX_6_Linux_Reference_Manual.pdf”
from the package documentation and use this driver as base for own design.

Have a great day,
Yuri

hi Yuri, i saw your direction and do following, but i find not thing about driver for ic display :smileysad:

[Yuri]

I meant using Freescale (MIPI DSI) driver only as base for further

development , assuming changing and debugging driver codes.

hi, have you porting guide driver for display??

[Yuri]

I am afraid we do not have detailed guide for display driver porting, sorry.
The Yocto "i.MX_6_BSP_Porting_Guide.pdf" contains only Chapter 6

(Connecting an LVDS Panel to an i.MX 6Dual/6Quad/6Solo/6DualLite
Reference Board).
