New page

This works for me with an input from a NES little box from walmart.
The sleep after loading the EDID file is important!
#!/bin/bash
set -x
sudo rm -rf csitest.yuv

MEDIA_DEVICE="/dev/media0" # change this if your media node differs

v4l2-ctl -d "/dev/v4l-subdev2" --set-edid=file="/home/rkeene/source/retroshark/X1301files/1080p60EDID.txt"
# Must sleep here to let the HDMI HAT sync with the video signal.
sleep 2

v4l2-ctl -d /dev/v4l-subdev2 --query-dv-timings
v4l2-ctl -d /dev/v4l-subdev2 --set-dv-bt-timings query

v4l2-ctl --list-devices
media-ctl -d "${MEDIA_DEVICE}" -r

media-ctl -d "${MEDIA_DEVICE}" -l "'csi2':4 -> 'rp1-cfe-csi2_ch0':0 [1]"
media-ctl -d "${MEDIA_DEVICE}" -V "'csi2':0 [fmt:RGB888_1X24/1920x1080 field:none colorspace:srgb]"
