SSP / IMX378 - Debian Stretch by deepeeess

Hi,

I am unable to use stillsample to capture an image using an IMX378 in Debian Stretch. I have Hexavision 0.92 and libssp 1.30 installed. My OS is fully patched (apt-get update && apt-get upgrade -y)

I know the hardware configuration is good because I can successfully capture images using an SD card with Debian Jessie installed. What I observe using Stretch is that the stillsample binary hangs while trying to "Write i2c: reg:0100 val:01” after “start streaming”.

The full output can be seen here:

Also, here is the strace of the same command:

And the output of i2cdetect:

Any help would be appreciated

Thank you,

Dan

Hi,

I can confirm the following procedure will allow for the installation of SSP on Debian Stretch:

1. Start with the 04-18 version of Raspbian.
2. Before updating the system, lock the version of libraspberrypi-dev with "sudo apt-mark hold libraspberrypi-dev”. It should be at version 1.20180417-1.
3. Install SSP 1.30 and Hexavision 0.92 based on https://www.visionproc.org.
4. Run "apt-get update" and "apt-get upgrade” to fully patch system.

stillsample will work using this method (tested all the way to kernel 4.14.70-v7+ with the most recent updates available today, 9/22/2018).
