Re: Convert HDMI out to in and CSI2 in to out

Hello 6by9, You have to make your output look exactly like the AR0323 - not an easy task. I thought I'd found a spec sheet for that sensor when you'd mentioned it before, but OnSemi don't have it listed on their Image Sensor Portal so I suspect a typo on the part number. This imager (AR0323) is a pr...

Re: Convert HDMI out to in and CSI2

What function does the FPGA perform, and can you not reproduce it in software on the Pi instead of the FPGA it is an Camera-based Advanced Driver Assistance Systems we try to test in our Lab. TBH I still haven't understood what HDMI source it is that you're trying to feed into this FPGA instead of ...

Re: Convert HDMI out to in and CSI2 in to out

Thank you 6by9.
it works like wished.
any idea of some good image processing Board?
I would like to continue with the Project I told you about.
I was looking for some Xilinx FPGA with HDMI Rx and CSI2 Tx for it. but there are all so expensif.
Thanks for all.

Re: Convert HDMI out to in and CSI2 in to out

control the B102 with CM3 using yavta but store the 8 mipi lane in an another Board. Is it possible with yavta please? when yes, do I have to change any part of the yavta.c code?

Re: Convert HDMI out to in and CSI2 in to out

As I said earlier, the CSI2 receiver driver doesn't actually care whether it receives data or not. If it does get some data then it will pass it on. If it doesn't then it'll sit there and wait hoping that it does. Just run yavta normally and it'll enable the B102/tc358743 to start streaming data ov...

Re: Convert HDMI out to in and CSI2 in to out

The tc358743 chip on the B102 can ONLY produce RGB888, YUV444, or UYVY. Your FPGA can ONLY consume raw Bayer as 10, 12, or 14 bits/pixel. There is no common format, therefore they can not be directly connected together. I have a DVD player with ONLY composite out. I have a monitor with ONLY HDMI in...

Re: Convert HDMI out to in and CSI2 in to out

The Pi doesn't have a CSI2 transmitter, therefore you can't implement that pipe. Like I wrote in one of my last Post, I don't really want to process the image with the Pi. I would like to save only the date from the B102 somewhere. control the B102 with CM3 using yavta but store the 8 mipi lane in ...

Re: Convert HDMI out to in and CSI2 in to out

I would query whether the FPGA is going to be set up to receive the CSI2 format that the B102 is going to produce - colour format, lane data frequency, number of lanes, termination and HS/LP switching is all configured by the Linux kernel driver for the tc358743 chip. If your FPGA isn't expecting t...

Re: Convert HDMI out to in and CSI2 in to out

Thanks again 6by9 for allways replying so quickly. You could do that, but there's little to gain from having the CM3 at all. The driver and hence I2C commands for the TC358743 chip are all in the Linux kernel driver for the chip. It almost seems more complex having the Pi send the I2C instead of the...

Redirecting output to stdout

hi everyone! I have some questions please. 1- what does " redirecting all Output to stdoutput means? 2- Is it possible to redirect the CSI2 data lane and clk lane to the GPIO Output from the CM3? 3- is it possible to control a camera with a CM3 (i2c from CM3 connect to i2c from the Kamera) but store...

I'm gonna try it now.
is the "h264" from

Code: Select all

"./yavta --capture=1000 -n 3 --encode-to=file.h264 -f UYVY -m -T /dev/video0"
support the RGB3 video format?

Re: HDMI to CSI-2 via TC358743 on kernel 4.1

Hello and big thanks again for your Help, On a CM or CM3, you need to decide which pins you're connecting up, and then choose either the same as the 3B/3B+ if 44&45, or the 0/0W/B+/2B if using 28&29. Yes you could use 0&1, but I haven't added parameters for that. You can also add "4lane=1" if using ...

Re: HDMI to CSI-2 via TC358743 on kernel 4.1

The HDMI timings set the capture resolution and frame rate. "v4l2-ctl --query-dv-timings" will tell you what mode has been detected. "v4l2-ctl --list-dv-timings" lists all the supported modes. "v4l2-ctl --set-dv-bt-timings <parameters>" allows you to set them (by index from list-dv-timings is easie...

And the problem was? Your experiences help others.
I did just enable the i2c and start all from the biginning. so I think the problem was i2c interface that wasn't enable on my module
