Banana Pi M64 (Allwinner A64): Getting the OV5640 camera to work under armbian with kernel 5.8


Recommended Posts

I am trying to get an OV5640 camera module to work on a Banana Pi M64 (Allwinner A64).  I am running Armbian 20.08.13 Focal with Linux 5.8.16-sunxi64. I have loaded the kernel sources, updated the config to include the ov5640 kernel driver module and updated the device tree, sun50i-a64-bananapi-m64.dts file by copying and adjusting the camera overlay code from sun50i-a64-pinetab.dts, but it is not working:

 

gollumm64% v4l2-ctl --list-devices
cedrus (platform:cedrus):
        /dev/video0
        /dev/media0

gollumm64% v4l2-ctl -d 0 --list-formats --list-ctrls

This is the dts code I added to sun50i-a64-bananapi-m64.dts:

 

i2c-csi {
		compatible = "i2c-gpio";
		sda-gpios = <&pio 4 13 GPIO_ACTIVE_HIGH>; /* PE13 */
		scl-gpios = <&pio 4 12 GPIO_ACTIVE_HIGH>; /* PE12 */
		i2c-gpio,delay-us = <5>;
		#address-cells = <1>;
		#size-cells = <0>;

		ov5640: camera@3c {
			compatible = "ovti,ov5640";
			reg = <0x3c>;
			pinctrl-names = "default";
			pinctrl-0 = <&csi_mclk_pin>;
			clocks = <&ccu CLK_CSI_MCLK>;
			clock-names = "xclk";

			AVDD-supply = <&reg_dldo3>;
			DOVDD-supply = <&reg_aldo1>;
			DVDD-supply = <&reg_eldo3>;
			reset-gpios = <&pio 4 16 GPIO_ACTIVE_LOW>; /* PE16 */
			powerdown-gpios = <&pio 4 17 GPIO_ACTIVE_HIGH>; /* PE17 */

			port {
				ov5640_ep: endpoint {
					remote-endpoint = <&csi_ep>;
					bus-width = <8>;
					hsync-active = <1>; /* Active high */
					vsync-active = <0>; /* Active low */
					data-active = <1>;  /* Active high */
					pclk-sample = <1>;  /* Rising */
				};
			};
		};
	};

&csi {
	status = "okay";

	port {
		#address-cells = <1>;
		#size-cells = <0>;

		csi_ep: endpoint {
			remote-endpoint = <&ov5640_ep>;
			bus-width = <8>;
			hsync-active = <1>; /* Active high */
			vsync-active = <0>; /* Active low */
			data-active = <1>;  /* Active high */
			pclk-sample = <1>;  /* Rising */
		};
	};
};

 

What am I missing?

I think the OV5640 was not probed.

I did not see anything wrong with the dts.

Review your kernel config for i2c bit-bang. It must be enabled.

OK, I changed CONFIG_I2C_GPIO from module (m) to built in (y):

 

gollumm64% cat /boot/config-`uname -r` | grep I2C | grep GPIO
CONFIG_I2C_ARB_GPIO_CHALLENGE=m
CONFIG_I2C_MUX_GPIO=m
CONFIG_I2C_CBUS_GPIO=m
CONFIG_I2C_GPIO=y
# CONFIG_I2C_GPIO_FAULT_INJECTOR is not set
# I2C GPIO expanders
# end of I2C GPIO expanders

 

No change.

Changing from 'm' to 'y' would not make a difference, so the problem is somewhere else.

 

You should see this:

 

[    3.999211] i2c-gpio i2c-csi: using lines 141 (SDA) and 140 (SCL)

 

 

Try this change:

 

        sda-gpios = <&pio 4 13 (GPIO_ACTIVE_HIGH|GPIO_OPEN_DRAIN|GPIO_PULL_UP)>; /* CSI0-SDA: PE13 */
        scl-gpios = <&pio 4 12 (GPIO_ACTIVE_HIGH|GPIO_OPEN_DRAIN|GPIO_PULL_UP)>; /* CSI0-SCK: PE12 */

OK, still no luck.  I looked for the I2C files under /sys and it looks like the ov5640 is seen, but I don't know if that actually means anything.

can you print the output of:

This is valid if ov5640 is enabled with 'm'

OK, got the sun6i_csi module built, now the addition /dev files are there, but running cheese raises an error:

I am also including the output from v4l2-ctl and media-ctl and lsmod for completeness.

 

Also: what do I need to do to be able to post more than one post per day on this forum?  Having to wait 24 hours between replies is tiresome.

You need to tell v4l2 some info prior to capture images.

 

Capture Images:

https://github.com/avafinger/fswebcam#mainline-kernel-support

 

I think is possible to grab images with 'Cheese' but you need to instruct Cheese to use the previous Image size set with media-ctl.

 

I don't understand how to format the command line for media-ctl.  There doesn't appear to be a man page for it and the example from the (scant) documentation for fswebcam does not match what I have.

I am not sure if I can give you a direct and correct answer without resorting to reading the code "sun6i_csi".  The format can be inferred from there.

 

A good reading:

https://linuxtv.org/downloads/presentations/summit_jun_2010/20100614-v4l2_summit-media.pdf
https://linuxtv.org/downloads/v4l-dvb-apis-new/userspace-api/v4l/v4l2.html

 

I don't use Zoom or GoToMetting, but basically any of these program to work must use the frame size and image format (yuv) set in media-ctl, if they try to get sensor capabilities and choose any one different from what you have set with media-ctl it won't work.

You need to enable "V4L platform devices" under Device Drivers > Multimedia support > Media drivers, then under "V4L platform devices" you want "Allwinner V3s Camera Sensor Interface driver" enabled as M.

Yes i did it, unfortunatelly stuck editing dts file. could you give me a start point to use customized dts. I found dtb file under "/build/cache/sources/linux-mainline/orange-pi-5.8/arch/arm64/boot/dts/allwinner/ " but how could i customize dts before compile the kernel, i dont understand. I mean, how to attach customized dts. Thanks for your help.

Yes i did it, unfortunatelly stuck editing dts file. could you give me a start point to use customized dts. I found dtb file under "/build/cache/sources/linux-mainline/orange-pi-5.8/arch/arm64/boot/dts/allwinner/ " but how could i customize dts before compile the kernel, i dont understand.  Thanks for your help.

 

I found a .dts file that was similar to my board and copy and pasted the parts relating to the camera to the dts file for mine, and then recompiled the dts to a dtb with "make dtbs" and then installed it using "make dtbs_install".  Do you have the schematic for your board?  That should show you which GPIO pins are used for the camera, so you can make the necessary changes to the device tree code you copied.

OK, make sure that the ov5640 module is also enabled.

Hi, I am working more than 4 days but no luck, could you share your dts and config file. I dont understand whats wrong. i get "ov5640 1-004c: ov5640_init_slave_id: failed with -6"  error

Thank you

A fragment of my DTS is elsewhere in this thread. Note: it is for a Banana Pi M64, which is probably different from your Pine64.  I got my working properly by refering to the schematic diagram I have for the Banana Pi M64.  You need to get the schematic diagram for your Pine64, so you know exactly which GPIO pines are wired to the CSI connector, then you can be sure that the DTS file properly sets up the correct GPIO pins to the correct functions.

Thanks for fast reply,First I changed them according to schematic and i checked, gpios are correct, if there was an issue on my camera or not connectted, could i see device wiith "v4l2-ctl --list-devices" ? Maybe there is a problem on camera hardware. Thank you

This error is: /* No such device or address */

 

You should double-check:

 

1. Is your sensor OV5640?

2. Check the connector, some are reversed 180º which is the case for BPI and Orange Pi. There is a Thread about it, 3 years old a think.

yes sensor is ov5640 and not reversed maybe there was a hardware issue, i dont know, i ordered a new one. Btw  i have a reversed one (BP camera). I double check everything but no luck. May i ask is ov5640 works without any issue with a64 (pine64) or could you advise any camera ? i need 30 fps 640x480 to process with opencv. Thank you

Yes, it works fine, but be careful with mainline kernel AVDD / DOVDD / DVDD supply, i have burned out 6 sensors with the wrong settings.

Search the forum for OV5640, i have advised one with ~130º lens if i remembered correctly. I would buy 2 or 3 from different  sources (or different models) since you are not sure what you will get.

Thank you @@lex i got my new OV5640 camera and working with 5.9.x  Cpu usage around %70 with opencv V4l2 capture fmt:UYVY8_2X8/640x480@30FPS and %60 with JPEG_1X8/640x480@30FPS.

It is higher than i expect. i thought csi camera uses GPU to grab image. Usb ov5640 cpu usage around %25 with similar settings. is it normal? Do you have any idea. Thank you.
