XISP : Creating new Pipeline Handler for AMD/Xilinx HLS-based ISP

[Mario Bergeron]

Hello,

I have made some progress on my XISP pipeline handler.

I am able to enumerate the four (4) cameras in my system:

# cam -l
...
Available cameras:
1: 'imx219' (/base/pl-bus/i2c at 80040000/sensor at 10)
2: 'imx708_wide' (/base/pl-bus/i2c at 80070000/sensor at 10)
3: 'imx500' (/base/pl-bus/i2c at 80090000/sensor at 1a)
4: 'imx477' (/base/pl-bus/i2c at 800b0000/sensor at 1a)


When I attempt to capture one frame, I get the following error message when
queueing buffers:

# cam -c1 -C1
...
Using camera /base/pl-bus/i2c at 80040000/sensor at 10 as cam0

Here is a version with more verbose :

The error may be caused by my code, but I am not certain what to
investigate/validate ...

Any help and/or collaboration would be greatly appreciated :)

Cheers !
