Realsense Firmware update by python script

[mksbabu]

Hi Team,

@MartyG-RealSense could you please help me to update firmware of D435 & D415 camera by python script or c++ code since I want to update firmware of realsense cameras by own code.

Thanks,
Spandana.

Hi Spandana, a C++ script for firmware update is at #7095 (comment) and a Python one is at #4416 (comment)

@MartyG-RealSense Thanks for info, I have tried with python code what you suggested but got below error. could you please help me on it.

Code:
import pyrealsense2 as rs
fw_file = "Signed_Image_UVC_5_15_1_0.bin"
ctx = rs.context()
dev = ctx.query_devices()[0]
print("device details: ", dev)
with open(fw_file, "rb") as fw:
dev.as_update_device().update(list(fw.read()))

Error log:
device details: <pyrealsense2.device: Intel RealSense D435 (S/N: 112322071995 FW: 5.15.0.2 on USB3.2)>
null pointer passed for argument "device"

Yes, bin file located in the same directory. When I ran above script, able to get expected result only once. If we rerun it again, getting above mentioned error for next attempts. After few hours of duration, getting successful result again. What's the issue here, could you please help me on it?

[MartyG-RealSense]

Is the firmware bin file located in the same folder as your Python program script, please?

Does the firmware update script below give better results?

import pyrealsense2 as rs
ctx = rs.context()

dev = ctx.query_devices()[0]
dev.as_updatable().enter_update_state()

import time
time.sleep(1)

dev = ctx.query_devices()[0]
dev.as_update_device().update(open("Signed_Image_UVC_5_15_1_0.bin", "rb").read())

@MartyG-RealSense
Yes the bin is located in the same folder. The above script is working frequently with large duration of time.

I have one more query related realsense cameras, we had an application with realsense cameras and also trying to update firmware of all cameras with same version, sometimes the camera is left in an unknown state such as D4XX. could you please explain this situation?

and also what is the recovery mode of realsense camera?

[MartyG-RealSense]

I'm pleased to hear that the alternative firmware update script is consistently successful for you.

If a camera is identified as 'Intel RealSense D4xx Recovery' then it indicates that a firmware update has failed and the camera has entered a recovery mode where it can be attempted to be restored to correct working order.

If the -r flag is used in the rs-fw-update firmware update tool then it will look for cameras that are in recovery mode and try to apply a specified firmware version to it. For example:

rs-fw-update -r -f Signed_Image_UVC_5_15_1_0.bin

@MartyG-RealSense As I am doing testing with several firmware versions, I am facing below issue to update firmware of camera with lower versions. could you please help me on it.

Error:
Firmware update started
Firmware update progress: 8[%]RealSense error calling rs2_update_firmware_cpp(device:00000133D74F3CD0, fw_image:00000133D7FA6060):
Device: 109223020606 is locked for update.
Use firmware version higher than: 5.15.1.0

[MartyG-RealSense]

RealSense cameras can only have their firmware downgraded to an older version 20 times during the camera's lifetime before downgrade becomes permanently locked. You can then only upgrade to a version newer than the one that is currently installed in the camera. There is no way to reset the counter.

This policy is described on page 104 of the current edition of the data sheet document for the 400 Series cameras.

Command: rs-fw-update -r -f Signed_Image_UVC_5_15_1_0.bin
@MartyG-RealSense If we have 2 or more cameras which are in recovery mode, will the above command recover all connected cameras which are in recovery mode or do we need to specify each camera with serial number to recover each camera?

[MartyG-RealSense]

The documentation of the rs-fw-update tool states that it recovers all connected devices which are in recovery mode.
