Struggling to get RAW frames

I’m trying to capture raw bayer frames from my IMX477 module i recently purchased. As far as I understand I need to bypass the internal ISP to do so, right ? Trying some examples always failed. In most cases, the v4l2-ctrl commands just freeze without any output. Weirdly enough getting processed frames using gstreamer works without any problems

  1. Where did you get the camera module(s)?
  2. Model number of the product(s)?
  3. What hardware/platform were you working on?
    Jetson Nano 4G on latest kernel with arducam driver
  4. Instructions you have followed. (link/manual/etc.)
    Capture Raw images from IMX477 with Nano - #2 by wong
  5. Problems you were having?
    python version fails to run due to problems with v4lc, the c version exits with “select timeout”
  6. The dmesg log from your hardware?
    [ 1.192609] hpd: state 7 (Takeover from bootloader), hpd 0, pending_hpd_evt 1 -
  7. Troubleshooting attempts you’ve made?
    testing the nvidia and arducam driver and testing different v4l2-ctrl commands to get raw data
  8. What help do you need?
