Driverless mode 393

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 for 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):
