SR Fails to Boot
a. Peregrine cannot access the secondary hard drive during boot up > Check cables connecting
to the hard drive.
b. Peregrine cannot communicate with Power Board > Check and replace USB-C cable.
a. Boot Media Unselected > Boot Media Reset Procedure + BIOS Time Reset (Below).
b. Botched Firmware Update > BIOS Time Reset (Below).
a. The most common signs that the peregrine is not booting are, within 5 minutes
● Gimbal does not boot up
● Lidar does not spool up
● Peregrine info does not appear on GCS
● Only 2 red LEDs on the Power Board instead of 4
● Black screen when connected to the HDMI port
In order to be recoverable, the peregrine must exhibit signs of life, including:
● Fan spinning
● Boot up beeps
● Red and green blinking LEDs on the lower rear quarter of the peregrine
1. Power cycle and wait up to 5 minutes.
2. Check for signs of life from the peregrine CPU:
a. Fan on top of the peregrine is spinning
b. Red and green LEDs on the rear underside of the peregrine
3. Check that the Power Board USB-C cable is securely connected to the Power Board and peregrine
inside the SR. Reboot and wait for up to 5 minutes.
4. Unplug the right 90-degree angle cable from the side of the camera and reboot, leaving the camera
unplugged. Reboot and wait for up to 5 minutes.
5. Check that the secondary hard drive (Samsung or Kingston) inside the SR is securely connected.
Remove the hot glue if necessary to check the two connections. Sometimes gentle pressure on the
connections can re-seat them. Reboot and wait for up to 5 minutes.
WARNING: Further troubleshooting should not be attempted without explicit instructions from SkySpecs
● FPV Monitor or other monitor with HDMI Input
● HDMI Cable
● Wireless Keyboard
Boot Media Reset Procedure
The peregrine can sometimes randomly “forget” which hard drive it should boot from causing the bootup
procedure to fail. If connected to a monitor, the peregrine will show the following message:
However, a monitor is not required to perform the Boot Media Reset Procedure which has proved effective at recovering peregrine which fail to boot.
1. Power down the SR.
2. Locate the red and black coin cell battery connection on the rear of the peregrine. Carefully disconnect
from the i7 board.
3. Locate the yellow jumper to the right of the coin cell port on the i7 board. This jumper bridges 2 of 3
pins. During normal operations the jumper bridges the 2 pins furthest from the coin cell port. Use
hemostats to carefully lift the jumper off and move it to the 2 pins NEAREST to the coin cell port. Leave
the jumper in this new position for at least 10 seconds.
4. Carefully return the jumper to its original position, bridging the 2 pins FURTHEST from the coin cell
5. Carefully reconnect the coin cell battery to the i7 board.
6. Power on the SR, if the procedure resolves the issue, within 5 minutes you should see the gimbal and
lidar power on. The peregrine should also connect to the tablet normallyvia microhard telemetry radio
Communicate with Tech Support before proceeding. It is normally recommended to perform multiple
power cycles to check for the peregrine to boot each time. At this point, inspections can be resumed but Idle Only takeoffs are recommended for the rest of the day. Log number should also be recorded as the timestamp will be incorrect until the BIOS time can be reset. The BIOS Time Reset Procedure (below)
can be performed at the end of the day after packaging logs.
Connect to Peregrine
Whenever the Boot Media Reset Procedure is performed, the BIOS time of the peregrine must be reset. When the time and date are incorrect, log timestamps will also be incorrect and the peregrine may not be able to accept firmware updates.
1. Power down the SR.
2. Open the front and rear panels of the SR.
3. Connect the HDMI cable from the port on the side of the peregrine to the port on the right side of the
4. Power on the FPV monitor and use the M button to select HDMI input.
5. Remove the USB dongle from the wireless keyboard. The keyboard has a micro-USB port on it but it
can only be used for charging. Connection must be made through the dongle.
6. Connect the USB dongle to the silver USB adapter near the front of the SR. This USB-A port is usually
occupied by the camera USB cable which can be temporarily removed.
7. Power on the wireless keyboard by sliding the switch on the side up. Notice a yellow blinking LED.9
8. Power on the SR and verify the wireless keyboard is connected to the peregrine. A solid green LED
should now be visible on the keyboard.
BIOS Time Reset
5. Power cycle the SR and begin to repeatedly press the ESC key on the keyboard until you see the
screen below with the BIOS menu. If you see the purple Ubuntu screen you will need to power cycle
and try again.
6. Use the arrow and return keys so select No under “Quit without saving.”
7. Use the <> arrow keys to select the Main tab.
8. Use the up/down arrow keys to highlight System Date.
9. Use the number and return keys to set the date using the MM/DD/YYYY format and verify the day.
10. Use the up/down arrow keys to highlight System Time.
11. Use the number and return keys to set the time to UTC TIME using the 24-hour format (This is NOT
local time). Complete accuracy is not necessary. Within 1 minute is acceptable.
12. Post a picture like the one above with the correct time and date to Tech Support so that it can be
13. Use the <> arrow keys to select the Save & Exit tab.
14. Highlight Save Changes and Exit and press the return key. Then select Yes and press the return key.
15. The peregrine will now reboot itself at least once. Eventually you should see the purple Ubuntu screen
indicating a successful boot. Check in with Tech Support before proceeding.
1. Power off the SR.
2. Power off the wireless keyboard.
3. Disconnect the HDMI cable from peregrine.
4. Disconnect the USB dongle and return it to the tray in the keyboard.
5. Re-connect the camera USB cable.
