Some subsystems don't react to runtime overlays dtoverlay=pca953x,addr=0x77,tca9539. You'll need to comment out your dtoverlay line to get it to boot, then fix the overlay and uncomment it again (unless you can fix the overlay from another Pi or computer). adding the line dtoverlay=gpio-ir,gpio_pull=up,gpio_pin=17 - result still pulled to ground 3. 5. Interrupts. I use the "dtoverlay=spi4-1cs". One for +5V (or +3V), one for GND, and the other one goes to a GPIO pin that is controlled by those settings Raspberry Pi Engineer & Forum Moderator Posts: 3393 Joined: Thu Jul 11, 2013 2:37 pm. Worth making explicit that config. txt file: dtoverlay=i2c_sensor,addr=si7020. As required pin multiplex settings and media-bus-formats for AT056TN53 were in the default tree now - with the stock overlay 'vc4-kms-dpi-at056tn53v1. 9. Question. A lower minpwm value, e. e. Confirm that the functionality has been disabled. 1 trejan Posts: 7548 Joined: Tue Jul 02, 2019 2:28 pm. Views expressed are still personal views. how do i activate my GPIO at boot with DT overlay? 1 post • Page 1 of 1. I have enabled I2C and added overlay in the /boot/config. Current value. #arm_freq=800 # Uncomment some or all of these to enable Code: Select all pi@raspberrypi:~ $ uname -a Linux raspberrypi 4. My main problem is that applying a logic low to pin 17 does not initiate shutdown - in fact nothing happens. This is the default on all except the Pi Zero which defaults to dwc2.
