Hi everyone,

I am having trouble running the initial node described in the documentation.

The main error is: [2579543.511]ERRORLOG/1 @ initVehicle, L215: Failed to initialize Linker channel

I feel as if the error revolves around what I set serial_name and acm_name to? Is there easy way to verify that the values I set to those two parameters are correct?

I am running Ubuntu 18.04 and ROS Melodic.

My output when I use the command "dmesg | grep tty" is:
[    2.476545] printk: console [tty0] enabled
[    4.577417] 00:05: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A
[    7.779445] cdc_acm 1-2:1.0: ttyACM0: USB ACM device
[  435.308771] cdc_acm 1-3:1.0: ttyACM1: USB ACM device

[  856.651303] cdc_acm 1-3:1.0: ttyACM0: USB ACM device


The entire output when I run "roslaunch dji_osdk_ros dji_sdk_node.launch" is this:

I have gotten past the point above, but now have the following output. I am at the max baud rate in the DJI Assistant, and do have API control on. It says the TX and RX pins could be inverted. How could I potentially fix this issue?

I have now created a whole new workspace with OSDK 3.8.1, and I get the following output. At this point, I am simply not sure what I am not including correctly.

/dev/ttyACM0  ==> This is not true.
May I ask what development platform you use? What is the serial port connect to the M600? USB-TTL device? If so, that would be /dev/ttyUSBx.
