Integrate ADV7280-M with IMX8X

eduardo3 — Thu, 13 Apr 2023 14:53:20 GMT

I am trying to integrate a ADV7280-M with our IMX8X board, but so far we have not been successful.

I am pasting here the device tree definitions and what we are getting on Linux.

Basically, there are 2 issues:

mxc-mipi-csi2.0: is_entity_link_setup, No remote pad found!

and

mxc-mipi-csi2.0: mipi_csi2_enum_framesizes, No remote pad found!

Not sure if the second one is a side effect of the first one.

We have a CVBS camera connected to the AIN1 of the ADV7280-M.

I've seen other posts about is_entity_link_setup but none helped me. Could anyone please review my configuration and advise how I should proceed here?

Attached part of the schematic as well.

Which bsp are you using?

Re: Integrate ADV7280-M with IMX8X

eduardo3 — Mon, 17 Apr 2023 08:12:51 GMT

NXP Yocto (Kirkstone), kernel 5.15.71. (5.15.71-2.2.0)

Any suggestions? Thanks.

Re: Integrate ADV7280-M with IMX8X

joanxie — Mon, 24 Apr 2023 09:23:44 GMT

did you use interlaced format? PAL or NTSC?

Re: Integrate ADV7280-M with IMX8X

eduardo3 — Mon, 24 Apr 2023 10:13:15 GMT

I am seeing that with PAL and NTSC cameras.

Re: Integrate ADV7280-M with IMX8X

joanxie — Fri, 28 Apr 2023 00:56:35 GMT

I assume that you set ADV7280 as BT656 mode, right? if yes, you need set ISI to deinterlace mode, if you use this, pls tell me, let me send the demo for android for your reference

Re: Integrate ADV7280-M with IMX8X

eduardo3 — Fri, 28 Apr 2023 13:22:35 GMT

Yes, I tried with and without "adv,force-bt656-4" to ADV7280-M device tree node (I am assuming this is the one as it is not mentioned in your reply). I don't see a deinterlace option in imx8-isi-cap.c or imx8-isi-core.c. Is this the thing you are talking about android example?

What I was hoping from NXP support is to get a device tree example how that should be configured (adv7280-m node, isi node, etc).

with adv,force-bt656-4, I still get:

you can refer to the link as below

Re: Integrate ADV7280-M with IMX8X

This is for reference for anyone having the same issue.

After adding debug info to ISI and MIPI-CSI2 drivers, adjusted the device tree to the following:

&i2c1 { adv7280m: adv7280m@21 { compatible = "adi,adv7280-m"; reg = <0x21>; status = "okay"; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_cvbs_int>; reset-gpios = <&gpioexp0 5 GPIO_ACTIVE_LOW>; powerdown-gpios = <&gpioexp0 6 GPIO_ACTIVE_LOW>; interrupts = <4 IRQ_TYPE_LEVEL_LOW>; interrupt-parent = <&lsio_gpio3>; interrupt-names = "adv7280m_intrq"; port { adv7280_ep: endpoint { remote-endpoint = <&mipi_csi0_ep>; data-lanes = <1>; clock-lanes = <0>; }; }; }; }; &mipi_csi_0 { status = "okay"; #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; mipi_csi0_ep: endpoint { remote-endpoint = <&adv7280_ep>; data-lanes = <1>; }; }; };

Adding virtual channels would cause failures. Also, the media/subdev functionality expects a link_setup function.

Added the following to adv7180.c:

static int adv7180_link_setup(struct media_entity *entity, const struct media_pad *local, const struct media_pad *remote, u32 flags) { return 0; } static const struct media_entity_operations adv7180_sd_entity_ops = { .link_setup = adv7180_link_setup, }; static int adv7180_probe(struct i2c_client *client, const struct i2c_device_id *id) { /* ... */ sd->entity.ops = &adv7180_sd_entity_ops; ret = media_entity_pads_init(&sd->entity, 1, &state->pad); /* ... */ }

With the changes above, I no longer get the "no remote pad found" error, I was able to use an analogue camera with our board.

We had to add further changes to adv7180 to be able to select its input (default is 0), we have 4 cameras connected to the board.

Also, ADV7280A-M has an I2P (interlace to progressive block), so the kernel was not patched for de-interlacing as suggested by support. I don't know if that is the right approach but I had to force the field format to be 'none' instead of 'alternate' so the height of the image is not halved. ISI won't upscale the image and that is the reason I've done that. If anyone has a suggestion, I would like to know it.
