Error with Release 0.21.0

[luca18]

I compiled the code from source on Ubuntu 18.04. I checked that the serial number matches SKU1 and updated the firmware to F450_4.0.0.37_SKU1_SIGNED.bin.

I get the following error when I run ./rsid-cli /dev/ttyACM0 usb

benlev commented 4 hours ago: Please try the following to see if it solves the issue: sudo systemctl stop ModemManager

If that doesn't work you could also check your LD_LIBRARY_PATH and ensure that you are not being linked to the wrong librsid.so. I had the same issue

[luca18]

@jvettese How do I ensure that I am not being linked to the wrong librsid.so? Where is the correct librsid.so and how did you link it to your LD_LIBRARY_PATH env variable?

[jvettese]

export LD_LIBRARY_PATH={PATH TO RSID LIB DIR} I have this set in my ~/.bashrc

You could also do sudo find / -name librsid.so to see where all librsid.so live

[luca18]

I tried both suggestions:

1. systemctl stop ModemManager

2. echo "export LD_LIBRARY_PATH=/home/luca/Projects/RealSenseID/build/lib/" >> ~/.bashrc source .bashrc

No luck.

Try re-generating the solution using RSID_SECURE=1 and re-run the sample - does it solve the issue?

[luca18]

After compiling with RSID_SECURE=1 and running ./rsid-cli /dev/ttyACM0 usb, I get the following error:

./rsid-cli: symbol lookup error: /home/luca/Projects/RealSenseID-Secure/build/lib/librsid_secure_helper.so: undefined symbol: mbedtls_hmac_drbg_random

This seems worse since I don't even get the prompt.

[luca18]

I've also noticed something that seems odd. When I compile with cmake .., I see this at the end:

-- Performing Test C_COMPILER_SUPPORTS_WFORMAT_SIGNEDNESS - Success -- Looking for pthread.h -- Looking for pthread.h - found -- Looking for pthread_create -- Looking for pthread_create - not found -- Looking for pthread_create in pthreads -- Looking for pthread_create in pthreads - not found -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - found -- Found Threads: TRUE
-- Configuring done -- Generating done -- Build files have been written to: /home/luca/Projects/RealSenseID-Secure/build

Is it normal that it says "not found" for two of the threads?

[3dsf]

@luca18 , did you get it working?

---

you are using linux, so this is normal

-- Looking for pthread_create - not found -- Looking for pthread_create in pthreads -- Looking for pthread_create in pthreads - not found -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - found

It checks for the non-linux first and then finds it when it checks for the linux location.

do this to disable modem manager (as per @alexk1976's advice) I've disabled modem manager for usb tethering reasons and I've never had an issue like you've experienced.

• sudo systemctl stop ModemManager
• sudo systemctl disable ModemManager

---

I've had a suspicion that you have more than one usb peripheral that uses a communication port and you might not be at /dev/ttyACM0 Confirm where it is connected by running sudo dmesg | grep 'Intel F450' -A 5 | grep ttyACM

[luca18]

I've tried everything that was suggested and nothing seems to work. I've also tried to run it on multiple ubuntu machines and a windows computer with no success whatsoever.

I thinking there might be a problem with the F450 camera that I have. It was working fine before the new firmware update. Is it possible to do a factory reset on the camera or downgrade to the old firmware?

[gabime]

Please try latest 0.22.0 version with the new FW and see if it solves your problem.

I solved the issue by following the solution posted at #47.
