/etc/fstab line for the SD I'm willing to mount looks like:
/dev/mmcblk1 /media/sd_card vfat user,rw,umask=000,sync 0 2
With this line I'm able to mount the SD, but everytime I want to unplug the SD I have to execute
blockdev --flushbufs /dev/mmcblk1 if I want to make the written changes take effect.
What means, that if I dont execute the
blockdev-command all the written changes are lost after unplugging the SD.
The weird thing is, that I all the time I was using this line, I thought everything is working fine...
So what am I doing wrong?
I'm working on the jetson tx2 with Ubuntu 16.04 running on it.
