Hi,

Define the OV5640 camera in M4 Core.

1. Configure the camera

• source/vendor/nxp/mcu-sdk-auto/SDK_MEK-MIMX8QM/boards/mekmimx8qm/demo_apps/rear_view_camera/ cm4_core1/isi_config.h

- #define CAMERA_DEVICE CAMERA_DEVICE_MAX9286

+ #define CAMERA_DEVICE CAMERA_DEVICE_OV5640

2. Resolve build error

• After I changed I got the build error,

/home/sek/gcc-arm-none-eabi-7-2018-q2-update/bin/../lib/gcc/arm-none-eabi/7.3.1/../../../../arm-none-eabi/bin/ld: ddr_release/rear_view_camera.elf section `.ncache' will not fit in region `m_data2'

/home/sek/gcc-arm-none-eabi-7-2018-q2-update/bin/../lib/gcc/arm-none-eabi/7.3.1/../../../../arm-none-eabi/bin/ld: region `m_data2' overflowed by 3874816 bytes

fixed by,

- m_data2 (RW) : ORIGIN = 0x89000000, LENGTH = 0x01800000
+ m_data2 (RW) : ORIGIN = 0x89000000, LENGTH = 0x01BB2000

But, I got kernel crash,

[   39.354186] kernel BUG at /home/emb-vinosek/Documents/VINOTH/IndiEV-IMX8-A9/source/vendor/nxp-opensource/kernel_imx/include/linux/dma-mapping.h:408!

I have the following questions regarding my implementation,

1. Is it everything OK ?

2. Do I needs to do some more configuration ?

Thanks & Regards,

If you increase m_data2, I think you should check the reserved-memory in Android device tree if there is any duplicate region.

Hi Chen King,

Thank you for  your reply and I fixed this issue and this is my patch,

-  m_data2 (RW) : ORIGIN = 0x89002800, LENGTH = 0x017FD800

+ m_data2 (RW) : ORIGIN = 0x89000000, LENGTH = 0x07000000

Thank You,

Vinoth S,

Hi VinothS

for iar "ncache" examples one can look at SDK_EVK-MIMX8M Mini, in

board.c, function BOARD_InitMemory()

Hi,

As per nxp release node (android_p9.0.0_2.1.1-auto-ga_doc/Android_Release_Notes),

camera MAX9826 is tested with imx8qm-mek. But, provided camera is ov5640 (i.MX 8 Series Accessory Boards | NXP )

So, I configured for ov5640.

source/vendor/nxp/mcu-sdk-auto/SDK_MEK-MIMX8QM/boards/mekmimx8qm/demo_apps/rear_view_camera/ cm4_core1/isi_config.h

- #define CAMERA_DEVICE CAMERA_DEVICE_MAX9286

+ #define CAMERA_DEVICE CAMERA_DEVICE_OV5640

After I changed the camera device only I got the build error. eventhough I fix this error by increasing m_data2 length, got kernel crash when using M4 console to start RVC.

Thanks & Regards,

VinothS,

Thank you Igorpadykov for your reply.

I fixed this build error by increasing the m_data2 lenght in the file MIMX8QM6xxxFF_cm4_core1_ddr_ram.ld

- m_data2 (RW) : ORIGIN = 0x89000000, LENGTH = 0x01800000
+ m_data2 (RW) : ORIGIN = 0x89000000, LENGTH = 0x01BB2000

I followed this thread https://community.nxp.com/message/1051954?commentID=1051954#comment-1051954 

Is it right way, What I am doing ?

Regards,

VinothS,
