Re: RB Pi 3 Active LED issue with Raspbian Stretch

Could you post the revision code (from /proc/cpuinfo) of those that work vs the that don't? It's just possible that there is something wrong in the config.

Re: uSDCard can't mount after Boot Raspi over USB

Secondly AFAIK the onboard SD card setup has no hotplug support, therefore if EMMC_EN_N_1V8 is in the correct state at boot then the kernel should find the SD card and create /dev/sda. I couldn't say for definite if there is a way to retrigger a scan of the bus. The EMMC_EN_N_1V8 has at boot not th...

Re: uSDCard can't mount after Boot Raspi over USB

Firstly do not touch GPIO47 on a CM3L. Refer to the schematics . Whilst on the CM1 GPIO47 is used for EMMC_EN_N_1V8 (as shown in Figure 1 of the datasheet), on CM3/CM3L a GPIO off an expander is used (as shown in Figure 2). GPIO47 is used for other purposes and messing with it will cause issues. Sec...

Re: Raw sensor access / CSI-2 receiver peripheral

There are settings in raspiraw for adv7282m (analogue video to csi bridge), but I never got them to work reliably. I now know they keep the clock lane in high speed mode, so I might revisit that as hopefully it will be about a two line change. ADV7282M setup now fixed on https://github.com/6by9/ras...

Re: CAMERA_0_UNICAM_PORT definition

Yes, camera_N_unicam_port sets up which set of clock and data pins are used for the csi data.
It is a little quirky that the default defines CAM1 socket as camera 0, but that's due to a copy/paste from the standard Pis where they only have one camera connector and it is unicam 1.

Re: CM3 working with only one camera, two detected

Minor correction to James.
I2C is used to both crypto and sensor, but the sensor I2C goes through a level shifter to 1V8 which is likely to shift the acceptable high and low voltages to it, but by the sounds of it even those are behaving erratically.

Re: Cheapest High speed camera up to 900 FPS!!

I'm not sure it is demosaicing at fault. I was fiddling yesterday trying to get a 320x240 mode running and was observing similar issues through the ISP. The standard mode 7 (VGA @ 90fps) doesn't suffer it, but as soon as you increase the skipping factor further on the sensor it throws it off, and it...

I've tried this out with a CM3 and two V2.1 camera modules with no issue using the stock config. Using your config and repatching 2&3 to 42&43 on the CMIO is also working fine. It has made me think of the IO bank supply voltages on GPIO0_27_VREF and GPIO28-45_VREF (SODIMM pins 39 & 41 by the looks o...

Re: Configuring i2c device before camera detection

Camera detection happens on first need of the camera information, ie either calling raspivid/still etc, or vcgencmd get_camera.
As long as you set up your extender before either of those occur then all should be fine.
