Cubie A5E + Camera 8M 219 (IMX219): ISP config name mismatch causes color artifacts at 1080p

Cubie Series A5E
1

Hi,

I’m trying to get a clean image from a Radxa Camera 8M 219 (IMX219 sensor) connected via MIPI CSI to a Radxa Cubie A5E (Allwinner A527, Debian Bullseye, Kernel 5.15.147-10-aw2501).

Current status: The hardware pipeline is fully working — the sensor is detected, the media controller topology is correctly wired, and GStreamer receives frames at 1920x1080 @ 30fps using:

gst-launch-1.0 \
  v4l2src device=/dev/video0 en-awisp=1 en-largemode=0 \
  ! video/x-raw,format=NV12,width=1920,height=1080,framerate=30/1 \
  ! videoconvert ! jpegenc \
  ! multifilesink location=/tmp/frame%03d.jpg

However, the image has severe color artifacts — diagonal red, green and yellow overlays across the entire frame. The scene is recognizable but clearly wrong.

Root cause identified:

The ISP log reveals the problem:

[ISP_WARN]cannot find imx219_1920_1080_1_0_0 isp config,
use imx219_3280_2464_30_0_0 -> [imx219_3280_2464_isp_cfg]

After inspecting the installed libraries with strings, I found a clear name mismatch:

libisp.so contains this mapping for imx219 at 1080p:

imx219  →  imx219_3280_2464_isp_cfg   (only full 4:3 resolution)
imx219  →  imx219_isp_cfg             (generic fallback)

libisp_ini.so (from libawispapi-isp-601-arm64) actually contains a 1080p config, but under a different name:

imx219_mipi_1080p_isp_cfg   ← exists in libisp_ini.so but is never requested

libisp.so searches for imx219_1920_1080_1_0_0 which exists in neither library. It falls back to the 4:3 full-resolution config which causes the color artifacts at 1080p.

What I’ve tried:

  • Installed task-a527-camera (which replaces libawispapi-isp-602 with libawispapi-isp-601) — same issue, same mismatch

  • Tried en-largemode=1 with 3280x2464 — produces no frames at all

  • Tried different Bayer orders (SRGGB, SGRBG) via media-ctl — no improvement, the issue is deeper

Question:

Is there a package or updated version of libisp.so that correctly maps imx219 at 1920x1080 to imx219_mipi_1080p_isp_cfg? Or is there another approach to get a clean 1080p image from the IMX219 on the A527?

Any help appreciated — happy to provide more logs or test patches.

Thanks!
