i.MX 8M Mini EVK & MIPI-DSI OLED Display

[msingh1920]

Hi Sir,

I have recently purchased the NXP iMX8M Mini EVK and MIPI-DSI OLED display but I am unable to get the panel to display anything.
I even followed the steps given in -

AN12189.pdf (Quick Start Guide for MX8-DSI-OLED1 for i.MX 8M Evaluation Kit ) but stil it's of no use. 

NOTE -
1. I am using NXP iMX8M Mini EVK
2. I am using MIPI-DSI OLED display
3. My iMX8 Mini display is running with Default Android OS shipped with iMX8 Mini  eMMC (Android 9.0)
4. Linux version is  4.14.78 

NOTE - I can see the Android running and its logo when i connect HDMI display to MIPI connector. 

Please help me how can i make display to be working. 

Any help with this would be greatly appreciated. 

Thanks & Regards,

Maneesh Singh

Hi Maneesh,

The mentioned application note is for the i.MX8M, while for your i.MX8M mini should be slightly different.

As basic detail, for using the OLED panel instead of the HDMI output, it is required to select the proper device tree file. Please refer to Table 10 “Kernel and device tree configurations” from “i.MX Linux Release Notes” document (from L4.14.78_1.0.0_LINUX_DOCS package), where it is mentioned that “Image-fsl-imx8mm-evk-rm67191.dtb” file is for using the OLED panel.

Hope this will be useful for you.
Best regards!

Dear Carlos,

I have a question for OLED Display in Linux 4.14.78.
Please let me know how to use the OLED in Linux 4.14.78.
When I used the prebuilt images and I changed the fdt_file as "fdt_file=fsl-imx8mm-evk-rm67191.dtb",
It seems that the U-Boot display is OK but the Kernel display is not OK.

Additionally I confirmed the Image-fsl-imx8mm-evk-rm67191.dtb and fsl-imx8mm-evk-rm67191.dtb are the same image in the built image folder.
- build-wayland_imx8mmevk/tmp/deploy/images/imx8mmevk.
In the folder, I could find the links for Image-fsl-imx8mm-evk-rm67191.dtb / fsl-imx8mm-evk-rm67191.dtb point to the same file.

So I think the DTB file is correct, there is another problem to display OLED in Linux like as "u-boot parameters / video".

Best Regards,
Eric.

Hi Kunal and T.Kashiwagi,

Thanks for your response.

I solved the issue of MIP-DSI_OLED display by referring to Android Quick Start Guide.
I am providing the steps which i did to solve the issue. Hope it will be helpful for others. 

Steps to Flash Prebuild Images using UUU utilities of NXP

1. Download the iMX8M Mini Prebuild Android OS Images from ink - 

https://www.nxp.com/support/developer-resources/evaluation-and-development-boards/i.mx-evaluation-an...

2. Download the UUU utilites from the below Link - 

https://github.com/NXPmicro/mfgtools/releases

3. Make it Executable 

# chmod a+x uuu 

4. For MIPI-DSI-OLED Display do the following
   changes as per “Android Quick Start Guide”  topics “Working with the i.MX 8M Mini EVK Board” 

   1. Refer 3.3.1 Directly invoking UUU with the lst scripts in command line to flash images

   2. Since we are trying to flash image in SDCARD and then boot from SDCARD we will use uuu-android-mx8mm-evk-sd.lst file

   3. open uuu-android-mx8mm-evk-sd.lst file

   4. rename vbmeta-imx8mm.img with vbmeta-imx8mm-mipi-panel.img

   5. rename dtbo-imx8mm.img with dtbo-imx8mm-mipi-panel.img

   6. if we are using HDMi display then no need to rename above files. It is by default 
      configured for HDMI Display.

5. Now connect OTG Port i.e Type C Port 1 with laptop

change the SW1101 as – 1010xxxxxx for serial download mode.

6. Connect SDCARD to iMX8M Mini Board, power on it and run the uuu script on PC with file name as below - 

sudo ./uuu /home/Maneesh/Downloads/android_p9.0.0_1.0.0-ga_image_8mmevk/uuu-android-mx8mm-evk-sd.lst

7. If everything is well we will get below msg - 

Success 1    Failure 0                                                                                                                                                                                                                                                                   3:4   21/21   [Done                        ] FB: done 

8. Once transfer is completed power off the board and to boot from the SDCARD change the sw position 
   as below -  

sw 1101 as 0110110010 and sw 1102 as 0001101000   

9. Connect the OLED with iMX8M Mini and if everything is well then we will be able to see the 
   Android Logo on the screen.

Boot Switch Setting =>

EMMC => sw 1101 as 0110110001 and sw 1102 as 0001010100
SDCARD => sw 1101 as 0110110010 and sw 1102 as 0001101000

Hope this will be helpful for someone. 

Thanks & Regards,

Hi maneeshsingh1920@gmail.com,

You can refer to the "Android Quick Start Guide" for testing the MIPI panel. I have attached the same for your reference, please refer section 3 of this guide.

Kunal

Hi Maneesh

Did you set "fdt_file" in u-boot?(I can't find it in your print env)

I do not know about Android, but the following commands can be used on Linux ( 4.14-sumo).

u-boot=> setenv fdt_file fsl-imx8mm-evk-rm67191.dtb

u-boot=> save

u-boot=> boot

Hi,

Is there anyone from NXP or from this community forum who can help me what steps i am missing
or what is the reason i am not able to see anything on MIP-DSI-OLED display. 

PF the Booting logs of my iMX8 Mini Board. 
I am booting iMX8 from eMMC (Default Android 9.0 Image) ... with HDMi Display and MIPI-DSI-OLED Display. 

NOTE -  I am not able to attach log files here hence pasting it below ---> 

Thanks & Regards,
