Writing Ros bag record to SD card in Jetson TX2

Hi,
I’m trying to record rosbag straight to the SD card in my Jetson TX2,
while recording in some stage when the bag gets to about 1.2-1.5GB size
The RAM memory of the process starts accumulating and then it explodes.
Its seems that at some stage its stop writing to the SD card.
I’ve seen these errors in the “dmesg”:

[ 0.000000] OF: fdt:memory scan node memory@80000000, reg size 16416,

Any idea how to fix it?

Hi,

Please share dmesg when error happened.

Which release are you using? Is it reproducible on nvidia devkit?

4

What part of dmesg do you need?

I’m using Jetpack 4.4
By devkit you mean to use the jetson in the dev kit not with the orbbity carrier board?

What part of dmesg do you need?

Does kernel report any error when you hit this error?

By devkit you mean to use the jetson in the dev kit not with the orbbity carrier board?

Yes, the nvidia development kit.
