Two cameras (CM3) question

[xasm]

Hi, 6by9!

So, the new thread. )

I'm trying to get 2 video signals using 2 B102 modules. The modules are connected to CAM0 and CAM1. I thought that it's possible to run 2 instances of mplayer and get video from 2 sources at the same time.

So, as I mentioned here: viewtopic.php?f=38&t=120702&start=475, one camera works perfectly. The question is how to start the second camera, because it seems that I have a hardware conflict somewhere.

vcgencmd get_camera reports Supported=2 connected=1

no dev/video1

I connected:

CD1_SDA ==> 28
CD1_SCL ==> 29
CD0_SDA ==> 44
CD0_SCL ==> 45

/boot/config.txt has line

dtoverlay=tc358743,i2c_pins_28_29=1

The question is, how to reconfigure the system and make it work?

[aBUGSworstnightmare]

You're on a Compute module, so question: do you have a dtblob.bin in place (configurimg your camera interface)? Enabling I2C only is not enough...

https://www.raspberrypi.org/documentati ... /README.md

Why didn't you post in Compute Module Section?

[6by9]

Your reference to connecting a second camera worried me that you were attaching a Pi camera module in addition to the tc358743. I'm glad that's not the case.
You do NOT need a dt-blob.bin if you are using the Linux kernel driver to talk to the sensor. However the existing overlays are only set up for using CAM0. As a second issue there is no current configuration that allows dynamic remuxing of i2c0 to different pins which is what you need to talk to 2 B102 boards. However there is nothing fundamentally stopping it if you write some device tree config.

Taking https://github.com/raspberrypi/linux/bl ... verlay.dts as a base, replace references to csi1 to csi0.

The easiest answer for i2c, either replace references to i2c_vc to i2c_arm and use GPIOs 2&3.

Alternatively there is a module i2c_mux_pinctrl that does allow dynamic pinmuxing. I had got most of it working on https://github.com/raspberrypi/linux/pull/2578, but trying to retain backwards compatibility was the issue. Each set of pins shows up as an individual /dev/i2cN device, with GPIOs 0&1 showing up as i2c0 and hopefully whatever is connected to the camera/display ports as i2c4 (tagged in the kernel as i2c_csi_dsi). There is a quirk that the base i2c controller still exists but not attached to any pins (it'll retain the last pin muxing). In the PR it shifts that away to i2c10 to be ignored.

You don't need to worry about backwards compatibility so can hack the DT around as much as you like. Configure it to have at least two sets of pins, name them as you see fit, and configure one tc358743 attached to each of the busses.

6by9, thank you for the reply.

I made the custom dts file (replaced i2c_vc with i2c_arm, csi1 with csi0, and i2c0 with i2c1. Additionally, I changed brcm,pins = <28 29>brcm,pins = <2 3> and connected CD0_SDA,CD0_SCL to pins 2,3). Full new dts file below:

I compiled the dts:

dtc -I dts -O dtb -o dt-blob-2cam.dtb dt-blob-2cam.dts
sudo cp dt-blob-2cam.dtb /boot/dt-blob.bin

Then, I added a line to /boot/config.txt

dtparam=i2c_arm=on
dtoverlay=tc358743,i2c_pins_28_29=1,i2c_pins_2_3=1

Video from the first B102 comes fine. But still no dev/video1

I'm sure that I did something wrong, could you please take a look? Thank you!

[6by9]

You need two overlays (*) - one to connect to csi1 and i2c_vc, and one to connect to csi0 and i2c_arm (or a mux).
The two overlays need to have different names to distinguish between them.

Overall you need to provide the config for all the devices - at the moment you've used my overlay for one B102, and your modified one for the other B102. Now load both together and you should get two /dev/video* devices.

(*) or one combined overlay. Up to you.

[xasm]

Hmm, different names - do you mean dt-blob.bin and for example dt-blob-2.bin?

I'll try. Actually, I expected that new overlay for i2c_arm kills settings for i2c_vc, but the first B102 still working good. So I suspect, that the overlay doesn't work as expected.

[6by9]

IGNORE dt-blob.bin / dt-blob.dts.. They are not relevant when driving everything from the Linux kernel.

Copy your modified tc358743-overlay.dts file to tc358743-csi0-overlays.dts.
Compile it, and copy the resulting tc358743-csi0.dtbo to /boot/overlays
Add "dtoverlay=tc358743-csi0" to /boot/config.txt

I'll try. Actually, I expected that new overlay for i2c_arm kills settings for i2c_vc, but the first B102 still working good. So I suspect, that the overlay doesn't work as expected.

Add "dtdebug=1" to /boot/config.txt and reboot. Run "sudo vcdbg log msg" and it will dump out the firmware log from where it was parsing the dtoverlays etc. I get lines like

That all looks good.
You can confirm by looking in /proc/device-tree which gives a directory style tree for the DT description.
Have a check under /proc/device-tree/soc/[email protected]/ for i2c_arm (should have a [email protected]/ directory), and /proc/device-tree/soc/[email protected]/ for Unicam0. Check the status nodes (use cat). Some of the entries are binary, so use xxd or similar to view them.
Check what's logged in dmesg whilst loading the modules. From what you've posted I'm expecting the B102 connected to CAM0 to be working with this.

[xasm]

Hmmm, this is a problem I guess:

[email protected] has no tc358743 directories, but I found the dir in [email protected] and in [email protected]

I see both /proc/device-tree/soc/[email protected]/ and /proc/device-tree/soc/[email protected]/ directories.

I guess, I missed changing something in the tc358743-overlay.dts.

Also, should I add i2c_pins_2_3=1 to config.txt? (actually, I tried, the result is the same - no /dev/video1)

Hmmm, this is a problem I guess:

[email protected] has no tc358743 directories, but I found the dir in [email protected] and in [email protected]

Typo on my part. There are 3 I2C controllers:
- [email protected] is i2c0
- [email protected] is i2c1
- [email protected] is i2c2, used by the HDMI (do not touch it!)
Check the "status" fields of each driver (although I'd be surprised if they weren't enabled).
Use "i2cdetect -y 0" and "i2cdetect -y 1" to confirm that your devices are responding on the appropriate busses. If the tc358743 kernel driver is loaded then it will have claimed the address and it will show as UU. "sudo rmmod bcm2835-unicam" "sudo rmmod tc358743" should release them and confirm if the devices respond.
Check the kernel log using dmesg for error messages.

I see both /proc/device-tree/soc/[email protected]/ and /proc/device-tree/soc/[email protected]/ directories.

OK, good.

I guess, I missed changing something in the tc358743-overlay.dts.

Also, should I add i2c_pins_2_3=1 to config.txt? (actually, I tried, the result is the same - no /dev/video1)

If you've defined the pin configuration to match where you've wired the devices to, then for your overlay you don't need to worry.
We add them to the generic overlays as people choose to wire things up differently.

I do have a B102 and B101 that I can try hooking up to see what I get. There should be no interdependencies between two instances of the same driver, but I've not tried it with these particular ones.

Nope, that will remap i2c0 to those pins whilst we want to remux i2c1.

depending on where you've connected it to.
DT should be throwing out the configuration for already claimed pins.

Hmm, I wired CD0_SDA==>2, CD0_CLS==>3 and I thought that i2c_pins_2_3-1 is the option. Should I configure the pins somewhere else?

Load that (I'm using GPIOs 44&45 with i2c1) and I get the B101 connected to CAM0 working.

Add in the overlay for the tc358743 on CAM1 and I see log lines saying they've all loaded, but it never completes the initialisation.

I think there may be something squiffy in the core code. V4L2 provides this thing called asynchronous subdevice registration. The CSI2 driver starts up and says it needs to wait for the TC358743 driver that it's been configured with, and the TC358743 driver says it needs to wait for the CSI driver. When both bits are loaded then it makes a callback to each of them and off we go.
That's working fine with one instance of each. When we have two identical instances it isn't triggering the callbacks for the second set.

I've just tried the tc358743-csi0 overlay with the adv7282m overlay (analogue video to CSI2), both load and I get /dev/video0 and /dev/video1.

It's going to require a modest amount of poking about in the kernel to work out what is going on. I will say that I'm on the 4.19 kernel that is being prepared for general use, but I'm seeing issues too. You can update too by using "sudo BRANCH=next rpi-update", but there's probably little point.

I hope it helps in investigation. Please, provide me a patch or a temporary solution as soon as you got it. And feel free to ask about some tests if needed.

Thank you again!

Hi, 6by9!

I just made another one test and got a quite strange result.

I changed dtoverlay lines - now the first one is dtoverlay=tc358743-csi0 and the second is dtoverlay=tc358743,i2c_pins_28_29=1

I expected that CAM0 will work and CAM1 will not. But in reality, I still see dev/video0 only and video still comes from CAM1.

Probably the issue is not in the kernel, but in dts file?

I don't believe so. Life is a touch complicated in that an overlay is just that - updating/overlaying an existing DT. The order of i2c0/i2c1 and csi0/csi1 will be the same whichever way around the overlays are specified, therefore the order that the kernel parses them in will be the same.
If there were something fundamentally wrong in the DT then just loading tc358743-csi0 wouldn't work.

You'll always get nodes numbered as /dev/video0 and incrementing. The function called is video_register_device, which takes a parameter of the preferred node number, or -1 for "use the next one". Some drivers do offer the option to specify their preferred node number, but relying on the ordering is not recommended. If I have a usb webcam plugged in at the same time as using tc358743 then the tc358743 is /dev/video2. If I'd requested video0 then I wouldn't get it as it was in use, and it would still be video2.

Minor error earlier - I'd switched Pis and was actually still on 4.14.79. Now I've rebuilt I'm on 4.19.2, but still the same issue.

[6by9]

Found. It was the dt overlay file. Both instances were calling their clock "bridge-clk", and even though one was under i2c_arm and one under i2c_vc they got confused/merged. The second tc358743 was therefore failing waiting for the clock to probe. When only one overlay was loaded there was no collision on the clock names, therefore it loaded OK.

is now working for me.
Wow, that took a while to dig through!

[6by9]

Tested further and can confirm that I can run yavta on both instances simultaneously (having found out that my DVD player doesn't seem to give an HDMI feed that the TC358743 can reliably lock on to!)

[xasm]

6by9, you are the best!

Everything works perfectly! Thank you for the fast and reliable support!

[xasm]

Hi 6by9!

You helped me wit 2xB102 2 months ago. Now, I'm trying to setup the system again, but something doesn't work.

As you menthioned, I didn't use dt-blob files, but it seems that something important was there

I made the following (with your last dts file):

Code: Select all

dtc -I dts -O dtb -o tc358743-overlay-csi0.dtb tc358743-overlay-csi0.dts
sudo cp tc358743-overlay-csi0.dtb /boot/ tc358743-overlay-csi0.bin

dtc -O dtb -o tc358743-csi0.dtbo tc358743-overlay-csi0.dts
sudo cp tc358743-csi0.dtbo /boot/overlays

To config.txt:

Code: Select all

dtparam=i2c_arm=on
dtoverlay=tc358743,i2c_pins_28_29=1
dtoverlay=tc358743-csi0

There are no video1, but it seems that second i2c is misconfigured - I see only "--" in i2cdetect -y 1 report.

Could you give me some advice how to fix it? Thank you!

[6by9]

First step is to confirm which of the two is actually probing - the first to fully probe will become /dev/video0 no matter which order you specify them in. Remove one dtoverlay line at a time from config.txt to confirm which is working and which isn't.

dtparam=i2c_arm=on shouldn't be needed as the overlay using i2c-1 should enable that anyway. Check that /dev/i2c-0 and /dev/i2c-1 both exist.

Use "raspi-gpio get" to confirm the pinmuxing. I'd expect
28 = SDA0
29 = SCL0
44 = SDA1
45 = SCL1
No other pins should report those functions.

Add "dtdebug=1" to config.txt, and then "sudo vcdbg log msg" will dump out a load of information from merging the overlays.

Anything useful in dmesg?

[xasm]

I connect:

28 = SDA0
29 = SCL0
2 = SDA1
3 = SCL1

/dev/i2c-0 and /dev/i2c-1 exist.

According the log both overlays are loaded.

I guess I missed something with installation process

[xasm]

Hmmm

When I commented "dtoverlay=tc358743-csi0" I got both correct reports with i2cdetect

Does it mean that dts file is not correct?
