Hi
we have two 3840*2160 camera connect to max96717 ---- max96712 ----orin。
so the data rate is 1.8G。
when i config max96712 data rate below1.5G（such as 1.4G）, i can rev images, but fps do not normal.
when the data rate config to 1.8G clk 900M， i can not rev images。

orin side i have already config serdes_pix_clk_hz = “600000000”;

the trace log below:

hello whn,

please refer to developer guide, you may check SerDes Pixel Clock session for details.
re-cap as below.

Skew calibration is required if sensor or deserializer is using DPHY, and the output data rate is > 1.5Gbps.

hence,
deskew calibration is a must if data-rate > 1.5 Gbps, Else the camera firmware will continue to wait for deskew signal from the sensor side. it’ll enable pixel parser when deskew calibration has completed.

FYI,
we got an issue that V4L v.s. Argus were having different timing for waiting deskew signal, the comparison result shows it’s Argus waits for signal too early. (we’re trying to resolve this internally)
you may test with V4L pipeline to check the stream status. then, it’s able to workaround by configure sensor state as standby (not streaming),

here’s camera firmware with debug flag enabled in order to obtain more details, i.e. Topic 226574.
it’s based-on JetPack-5.0.2/l4t-r35.1, however, it still works on JP-5.1 for debug purpose.

Hi jerry
i update the firmware and catch the trace log.please find the attached file.

max96712 is work DPHY mode, i config max96712 work in 1.5G data rate per lane, and enable deskew .
trace.log (110.9 KB)

5

by the way, i use v4l2-ctrl to capture images.
the trace log , i can not understand please help ~~~

hello whn,

it seems there’s an issue with deskew.

rtcpu_string: tstamp:7172781761 id:0x04010000 str:"Deskew sweep could not find a valid clock eye opening"
rtcpu_string: tstamp:7172782180 id:0x04010000 str:"deskew: data status_bits:0x0

also,
there’re errors trigger by PHY interrupts.
the error code 0x110, it’s bit-4 and bit-8, that means data-lane [A/B] FIFO overflow.
for example,

rtcpu_nvcsi_intr: tstamp:7173249108 class:GLOBAL type:PHY_INTR0 phy:0 cil:0 st:0 vc:0 status:0x00000110
rtcpu_nvcsi_intr: tstamp:7173249108 class:GLOBAL type:PHY_INTR0 phy:0 cil:1 st:0 vc:0 status:0x00000110

could you please try issue a reset signal below s_stream?

Hi Jerry
the deskew issue means the deser do not send corrcet deskew data???

10

this means??? reset csi phy???

11

I meant reset the SerDes chip before s_stream.
