Integrate YUV sensor for IPNC App V2.6
I am working with IPNC DM368 App V2.6. I tried to compile the cramfs and kernel follow the YUV sensor driver integration document but I can't not run it.
I always get some problem relate to memory, and module load. My question is: what kinds of UBL and UBOOT should I use for EVM board in this case, please share me them if you already have? and What is Bootarg setting for EVM. I didn't see any document relate to this information, I guess this make my trouble.
Since you are trying to integrate to IPNC 2.6 the uboot and UBL should not cause these issue. Could you share the log of the error so we could analyse it. The bootargs which we follow are given below
setenv bootargs mem=48M console=ttyS0,115200n8 root=/dev/nfs rw noinitrd ip=dhcp eth=<ETH ID>nfsroot=<NFS PATH>,nolock
Firstly, I think I should explain a bit about my working. We have a board that design similar to IPNC camera except YUV input came from Sony modules (720P 422), not Apt Sensor. We were Edited the original source of V2.6 by ignore the I2C configuration, support YUV mode .... similar to YUV sensor integrate document.
I got a bit result after some days working but still have problem in video color. Please check out the attached image for more detail.
It look like the system was missed the Y element of YUV space. By your experiences, please help me to show out where is that issue.
thanks so much.
looks like Y/C components are swapped.
You can verify this by manually changing the ISIF.CCDCFG.YCINSWP or if you are using 8bit mode, ISIF.CCDCFG.Y8POS
I have same problem
I use 8bit YUV mode.
I'm already tested ISIF.CCDCFG.P8POS bit set or clear, but it is same status... like above captured images.
you should set the parameter as below:
miscConfig.ycInSwap = FALSE;
inDataConfig.inDataType = CSL_CCDC_IN_DATA_TYPE_YUV16;
// turn on the REC 656 mode
setup.rec656Config = &rec656Config;
inDataConfig.yPos = CSL_CCDC_Y_POS_ODD;
sdrOutConfig.packMode = CSL_CCDC_SDR_OUT_TYPE_16BITS_PER_PIXEL;
hope they can help.
We have same promblems.It seems Y/C components are sawapped.we are using 16bit YUV mode with IPNC3.2.Can you tell me how to solve it?thanks very much.
the image with the color problems as below:
Have you solved this problem? we have a same problem ,maybe you can help us ,thanks a lot.
I have same issue do your know how to fix it ,thanks!
