[joanxie]

did you use external ISP? if yes, how did you add this ISP in the dts file? pls share the detailed information about this

[udhayamoorthi]

I didn’t use ISP. how can I add ISP in imx8m mini?

[joanxie]

you need add external ISP chip (HW) if you need to use it, imx8mm doesn't have ISP module like imx8mp

we have tested AP1302 on imx8mm successfully, maybe you can evaluate this

[udhayamoorthi]

when I am running gstreamer command I’m getting this do have any idea about this?

[joanxie]

current bsp doesn't support raw12 as default, did you change the source code for raw 12 format support? you can find this from logfile:

"mipi_csi: format not match"

[udhayamoorthi]

@joanxie yes it was showing format not match..i am working on custom camera so does not support isp and if i use SOFTisp (software isp),i cannot able to use softisp on linux or my board(imx8mm).. what should i do? how can i able to stream on custom camera on imx8mm ?

[joanxie]

what softISP do you use? currently nxp softISP based on openCL on imx8mq and openVX on imx8, what do you use for your softISP?

[udhayamoorthi]

i didn't use any isp. how can i stream without isp on imx8mm? whenever i use gstreamer it is showing "internel data stream error".

[joanxie]

as I mentioned before, imx8mm can capture but couldn't handle raw data, we have solution with external ISP, if you don't use this, maybe you can use your own SW to handle this, but we don't have such demo for this

[udhayamoorthi]

do you have the driver code for raw 10 bit on imx8mm?

[joanxie]

you can add this in the mx6s_capture.c

case V4L2_PIX_FMT_SBGGR10:

cr1 &= ~BIT_PIXEL_BIT;
cr18 |= BIT_MIPI_DATA_FORMAT_RAW10;

break;

[udhayamoorthi]

if i can able to capture raw10 then i don't need isp because i already capture with raw8 without using isp

[joanxie]

as I mentioned before, imx8mm can capture raw data, but couldn't convert raw data to any rgb or yuv data without ISP, if you need more detailed information about how to capture raw data, pls create a new case for this topic

[udhayamoorthi]

refer this thread

https://community.nxp.com/t5/i-MX-Processors/Unable-to-get-RAW10-format-for-ov5630-sensor-with-imx8m...

[udhayamoorthi]

i have added these and still didn't get raw10.can you share me any capture code using raw10?
