roslaunch razor_imu_9dof razor-pub.launch error

[carl1218]

hi,
My system is 64 bits.i used the KristofRobot/razor_imu_9dof firmware.
when i run the launch，I got the following error.

Can you confirm you are loaded the custom firmware (from src/Razor_AHRS/Razor_AHRS.ino) on the IMU? See "Install Arduino firmware" step in the README.

i have some problems, when i use arduino upload the Razor_AHRS.ino, it has some errors
as followers:

Binary sketch size: 21,538 bytes (of a 30,720 byte maximum)
avrdude: stk500_initialize(): (a) protocol error, expect=0x14, resp=0x23
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x59

Hello,

I get the following:

ERROR: cannot launch node of type [sparkfun_9dof_razor_imu_m0/driver_node]: sparkfun_9dof_razor_imu_m0
ROS path [0]=/opt/ros/kinetic/share/ros
ROS path [1]=/home/nvidia/racecar-ws/src
ROS path [2]=/opt/ros/kinetic/share

I have the appropriate Firmware.

Nothing seems to work. The 3D vizualiser also does not display anything, yet the Arduino IDE does display the imu values.

Any ideas?

Cheers!

@CapitalZe it seems like the package is not properly installed or the system can not find the path to the package. Try a "roscd razor_imu_9dof" and see if it can find the package

@KristofRobot I am arriving at the same error as @carl1218 and I have already loaded the custom software on the IMU. Was this ever solved? Please help.
