Description

Instructions on how to disable sensor driver and get images from image sensor (for MT9F002 sensor)


Instructions

pre

  • to load bitstream for MT9F002 appropriate changes need to be made to:
    • device tree
set sensors to mt9f002 in elphel393-detect_sensors,sensors entry
    • /etc/elphel393/default_10389.xml for setup w/o 10389 or 10389's eeprom otherwise write MT9F002 as application
  • Disable driver
root@elphel393~# touch /etc/elphel393/disable_driver
# then reboot

init

  • start python session:
root@elphel393~# cd /usr/local/verilog/; test_mcntrl.py @hargs-after
  • init (if the driver is not disabled the i2c writes will not work):
