I am using a Jetson Tx2 with an Arduino (adafruit Feather M0, SAMD ARM cortex M0), but can’t seem to communicate.
The configuration is:
head -n 2 /etc/nv_tegra_release
R32 (release), REVISION: 2.1, GCID: 16294929, BOARD: t186ref, EABI: aarch64, DATE: Tue Aug 13 04:45:36 UTC 2019
I can see the device connect and ttyACM0 is there, but serial communication is not working:
[ 61.544648] cdc_acm 1-2.3.4:1.0: ttyACM0: USB ACM device
[ 457.852932] usb 1-2.3.4: USB disconnect, device number 8

[ 461.423789] cdc_acm 1-2.3.4:1.0: ttyACM0: USB ACM device
I saw some other topics detailing how the install ACM modules on older R28 versions, but do not see anything for R32.
I have another Jetson Tx2 that is copy exact, and can communicate with the M0 device on it.
I am unsure how to go about resolving this issue.
