You might want to reduce the memory you've given to the GPU. When you use the libcamera apps, they use memory from the CPU - not the GPU, so if you give too much memory to the GPU - you limit the capabiltiies for allocating camera buffers.

hi, /boot/config.txt

[all] dtparam=act_led_trigger=default-on gpu_mem=76 camera_auto_detect=1 dtoverlay=vc4-fkms-v3d

dtoverlay=imx477

libcamera is working (but no preview under X) by enable dtoverlay=vc4-fkms-v3d also the old dtoverlay=vc4-kms-v3d you can run libcamera under /bin/bash

also look at

Thanks @cortmen, that seemed to do the trick.

@kbingham I tried your suggestion first and lowered GPU memory to 16MB but still received the same error

For anyone running on Bullseye, all I need to do is edit my /boot/config.txt to uncomment the line # Enable DRM VC4 V3D driver dtoverlay=vc4-kms-v3d

Then I rebooted and ran this command successfully for the first time: libcamera-still -n -o test1.jpg --viewfinder-width 1920 --viewfinder-height 1080
