I see your avatar is missing, was that a recent upload?  The file backup was a couple of weeks old, the database was fresh.

Raspberry Pi / Re: libcamera

On TC13 lsmod does list i2c-mux and i2c-mux-pinctrl-pinctrl along with imx219, but on TC14 it does not. I discovered a useful tool insmod with which I could load imx219 from the kernel.tclocal and then it shows up in lsmod also on TC14. But I don't find the i2c muxes folder on TC14 at all... maybe it was built into the kernel and just a red herring.

But I guess that perhaps it's noteworthy that imx219 doesn't show up on TC14, even though I got camera_auto_detect, start_x and dtoverlay=im219 in the config file, along with dtparam=i2c_arm=on.

Thank for the input Rich! 8)

I'm a JavaScript developer and not well versed in the intricacies of Linux, so there be dragons. Anyway since I don't know much about how Linux works, I created a delta between TC13 and TC14 and started to compare the two.

Studying the delta of dmesg logs, I noticed that something called imx219 was not showing up in TC14 while in TC13 it is ("imx219 10-0010: Consider updating driver imx219 to match on endpoints"). imx219 sees to be related to picamera. It also seems as though imx219 is dependent on i2c. While lsmod on TC14 does lists i2c, when I run cat /lib/modules/<piCore-version>/modules.dep and compared the two, there was a lot of i2c use on TC13, but in the kernel dep on TC14, i2c is barely mentioned.  There is only one mention of imx219 on both of the systems: kernel.tclocal/drivers/media/i2c/imx219.ko but while im219 depends on kernel.tclocal/drivers/media/v4l2-core/v4l2-fwnode.ko kernel on TC13, on TC14 it depends on v4l2-async.ko (a ko that does not exist on TC13).

i2c and v4l2-async seems to serve different purposes.

Adding to config.txt: dtoverlay=imx219, startx=1 doesn't fix the problem, so this is where I'm at right now:
Maybe i2c is not properly loaded or something on TC14, or maybe v4l2-async fails at registering the camera.

Will investigate further...

Regarding Forums and Wiki migration to new server - Thanks and congratulations to Paul_123 and the team for handling this!  Bringing the wiki back to life is -huge-.

Can you check to make sure I added the vc4.conf file?

I just updated to piCore15.0 Beta armhf by copying over files to an sd card containing piCore-13.x running on an RPi3.

piCore-15.x booted and after copying over xorg-server (for the vc4 snippet) and graphics-KERNEL, the gui started.

I then updated all the extensions (due to the change in squashfs block size they are all marked for update) and now the gui will not start.

* I added the missing cairo dep to the harfbuzz dep file
* I created the missing llvm15-lib dep file containing gcc_libs, libzstd, ncurses and libxml2
* cairo-sphinx is missing a dep on pcre (this will probably disappear if compiled without pcre present).

There are no errors in Xorg.0.log, it looks like a normal startup - xorg does not start from boot due to the race condition loading modules, but starts with startx to a blank screen.

Strangely the screen comes up at 2048x1152, when I would have expected it to come up at 4khd or hd, but perhaps that's a limitation of the RPi3. If I add a snippet to set the screen to 1920x1080, it still comes up blank.

dmesg gives this:
