Hello,
I'm trying to use Portsdown4 with a picam V1 (OV5647) but I've never managed to TX using it after following the installation recommanded.
I put "dtoverly=ov5647" and "start_x=1" in the config.txt.
"vcgencmd get_camera" returns me "vcgencmd get_camera supported=1 detected=0 libcamera interfaces=1"
"raspistill" command returns me an error telling me to use legacy stack.
I tried to install libcamera-apps which permits me to see images using "libcamera-hello" but portsdown4 never transmit when I select "Picam" as source.
Any ideas ?
Thnaks a lot for your help,

I see that the OV5467 is not the official Raspberry Pi camera, although it claims to be compatible.
The Portsdown 4 has only been tested with the offcial Raspberry Pi Camera V1, V2 and HQ. It does not work with the V3. No other CSI-connected cameras are supported.
If the OV5467 is truly compatible, you should not need to make any modifciations to the config.txt file. So try without the 2 extra lines that you have added (you'll need to reboot).
If that does not work, try with just "dtoverlay=ov5647". Note the correct spelling of dtoverlay - you had it wrong above.
If that does not work, please buy a genuine Raspberry Pi Camera V1 or V2.

Re: Portsdown 4 picam OV5647
I have used a cheap copy RPI (marked as a V1.3) and it was fine other than its back-light handling. Now used as a source for the BATC Video Source project and I have fitted 'real' cameras in my PD4's.
The cheap units have 3 SMD transistors on the back like this one eBay item 395358264149 but for not much more a genuine camera can be had such as this eBay item 266886148551.
Very useful for portable work in case your usual camera is left at home or fails....

Hi Dave,
On the following page, you can find a chart that tell us that the OV5647 corresponds to the official camera V1 from Raspberry :
https://www.raspberrypi.com/documentati ... amera.html
I bought this two cameras :
https://www.amazon.fr/dp/B07GNHXGD9
https://www.amazon.fr/AZDelivery-Cam%C3 ... 01M6UCEM5/ (the same as Gareth told)
My mistake was to try to make the RPI driver work by modifying the /boot/config.txt file. But you made a super job that permits Portsdown to work without that. The only problem I still get is that the PiCam Monitor do not work : I think it is for that I came into the modificition of the config.txt. Indeed, before try to transmit, I would like to see the image using Picam monitor but this function never worked here (using webcontrol only) so I never try to transmit...
Now, I removed all lines in config.txt I added (the only one that is mandatory is "dtparam=i2c_arm=on") and when I transmit my lime goes TX and I received images on SDRAngel at the other end with a RTLSDR.
Thanks a lot for your work !
One more question : Is there a way to reduce the very large latency I get on the received images ? I'm using SR250 and FEC 1/2 but it seems to be the same thing with higher SR or FEC.
