Hello,
I am having issues with IMX298 module ( purchased from local reseller:
https://kamami.pl/kamery/576988-arducam-b0174-imx298-mipi-16mpx-modul-kamery-dla-raspberry-pi.html )
Following the manuals I have successfully compiled the SDK from
https://github.com/ArduCAM/MIPI_Camera/
for RPI3 B+ and RPI Zero. In case of both RPI models the gpu_mem is set to high value above 256MB but when selecting resolution mode 3 and 4 (width: 4656, height: 3496) for arducamstill I am getting memory allocation error:

Selecting lower resolutions, gives me an image with green tint:
Any help would be appreciated.
