Camera with specific resolutions couldn't preview on imx8MM

Dear NXP Team,
I enabled a camera(Onsemi AP1302 + AR0144) on imx8MM, but it cannot preview when I want to preview specific resolutions.
The camera supports two resolutions, 1280x720(720p) and 1280x800(sensor full size).
However, I tried to enable the camera but it couldn't be enabled before I modified the mipi-csi clock-frequency & camera MIPI setting.
Finally, I success to enable the camera with 720p, but full size still can't be enabled.
I don't know why full size can't, I really wonder that.
My current setting is camera MIPI speed is 400M, mipi-csi clock-frequency is 400M.
fragment@1 {
target = <&mipi_csi_1>;
__overlay__ {
status = "okay";
#address-cells = <1>;
#size-cells = <0>;
clock-frequency = <400000000>;
port {
mipi1_sensor_ep: endpoint@1 {
remote-endpoint = <&tevi_ap1302_1_ep>;
data-lanes = <4>;
csis-hs-settle = <13>;
csis-clk-settle = <2>;
csis-wclk;
};
};
};
};
I don't know how to understand mipi-csi setting about "csis-hs-settle" & "csi-clk-settle", and I don't understand how to set the mipi-csi clock-frequency is better. I cannot find any document to describe them and I only found it but there is still no detail about these settings.
Explenation for HS-SETTLE parameter in MIPI CSI D-PHY registers
How do I decide these settings to enable the camera?

if you set 1280x800, what do you mean couldn't enable? what error logfile do you get? pls share the logfile for this resolution, and give me more detailed information

Hi @joanxie:
Do you have any updates about this issue?
I tried to read CSI_CR19 (0x32E2_004C) but I didn't find the value was overflow (over 255?).
I tried it like below that:

If I open 1280x720, it never triggers mipi_csis_irq_handler and it always can work.
I don't know why the different resolutions have different situations.
Do you have any ideas?

Updated 2022.03.31:
I found it doesn't trigger mipi_csis_irq_handler but mx6s_csi_irq_handler if I enable 1280x720. But If I enable 1280x800, it firstly triggers mx6s_csi_irq_handler, then it triggers mipi_csis_irq_handler and gets FIFO overflow Error. \
I trace that below:
1. 1280x720 (always work

I don't know why they are different when I enable the different resolutions.
I think maybe the issue is related to FIFO overflow Error.
I tried to find some discussion about that:
https://community.nxp.com/t5/i-MX-Processors/FIFO-Overflow-error-on-low-resolution/m-p/1154998
But there is no solution for imx8MM but imx8MQ because I cannot find a similar register on imx8MM to CSI_PHY_CTL_REG(0x30A7_0104) on imx8MQ.
And CSI_PHY_CTL_REG just can only disable lanes so I'm not sure that the solution is correct.
How could I understand the cause of FIFO overflow error?
Is there a better solution for imx8MM?

how about unit test like：
“/unit_tests/V4L2/mx6s_v4l2_cap_drm.out ”？？

Hi @joanxie ,
I tried to use mx6s_v4l2_cap_drm.out, but got an error.

$ /unit_tests/V4L2/mx6s_v4l2_cap_drm.out -d /dev/video0 -fr 30 -m 4 -ow 1280 -oh 800 -of test.raw
try this command, you can change the parameter as your demands, you can use ./mx6s_cap_drm.out -help to get more detailed information

Hi @joanxie
Yes, I tried again but it still returned the same error whether I tried what parameters I set. like below:
root@edm-g-imx8mm:~# /unit_tests/V4L2/mx6s_v4l2_cap_drm.out -d /dev/video0 -ow 1280 -oh 800 -of test.raw

I use gstreamer to test our camera, below that:
Camera: MIPI speed=400M
CSI: mxc_mipi-csi 32e30000.mipi_csi: lanes: 4, hs_settle: 13, clk_settle: 2, wclk: 1, freq: 400000000

I think it just cannot decode the MIPI data, and the problem is related clock frequency.
However, I don't know how to decide the better clock-frequency and how to decide the better camera's mipi speed.
Despite using the default clock-frequency 333M, it still has the same problem.
By the way, If I firstly enable 1280x800 for the camera, it can work! But it only can work the first time.
If I want to enable 1280x800 again, it cannot work and doesn't preview any image.
Then 1280x720 always can work whenever I enabled the camera.
