i.mx8mp 5M Capture

kiyoung — Tue, 17 Oct 2023 04:26:46 GMT

5M(2616*1940) camera does not work well.
The ISP disables it and I want raw capture.
There is a size limit in ISI, so it operates normally up to 2048 width, but beyond that, incorrect video is captured.
As follow the code in imx8-isi-hw.c, bypass mode is used, and chain buffer is used when the width is greater than 2048.
The final goal is to operate 5M and 13M Cameras simultaneously on i.mx8mp, but I want to check 5M single first.
5M Camera is connected to CSI1, and CSI0 is not in use yet (disabled).
Where should I review?

OK8MP-C.dts
&mipi_csi_0 {
status = "disable";
};

&mipi_csi_1 {
status = "okay";

port@1 {
reg = <1>;
mipi_csi1_ep: endpoint {
remote-endpoint = <&imx335_mipi_1_ep>;
data-lanes = <4>;
csis-hs-settle = <26>;
csis-clk-settle = <4>;
csis-wclk;
};
};
};

&isi_0 {
status = "disabled";
};

&isi_1 {
status = "okay";
cap_device {
status = "okay";
};
m2m_device {
status = "disabled";
};
};

5M Camera is connected to CSI1, and CSI0 is not in use yet (disabled).
It is currently configured as single, and the 2048 width is normal, but the 2616 width is not normal.
It cannot be any size smaller than the single 4K you mentioned in the link.

try the CSI0, the CSI1 should be set 266M as default
