How to create a camera iq file?

[pitchaya]

Hi,
How do you create camera iq file? We developed a kernel driver for a sensor. It works fine, but we would like to be able to us the ISP and 3A. Can anyone help us point to the direction?

it's looks like it's no official document for writing IQ file.
you may find(and, probably, already did) some info in rockchip github repos, like a camera_engine_cifisp or camera_engine_rkisp, or kernel itself, but all that info required reverse-engineering.

IQ file support versions(code_xml_parse_version), so you need to be sure to use the same version, as rkisp support (IQ file not backward-compatible, and may not forward-compatible too)
