Sorry, /media is not a symlink and there is no /run/media link or directory present on my running system. When I insert an SD card, for example, I get a bit of text on the debug serial port that a card has been detected, but I don't see a mount point anywhere after that.
root@mySys:/# mmc1: new high speed SDHC card at address 1234 mmcblk1: mmc1:1234 SA04G 3.63 GiB mmcblk1: p1 It should be noted that if I exclude the " read-only-rootfs" option in the bb script, a normal read/write kernel image is produced and the action of inserting an SD card under those conditions will automatically produce a mount point at /media/mmcblk1p1 FYI, I'm running 3.14 kernel. Is this a job for aufs? If so, how would I go about configuring it? -----Original Message----- From: Mike Looijmans [mailto:mike.looijm...@topic.nl] Sent: Tuesday, June 14, 2016 9:18 AM To: Christopher Larson <clar...@kergoth.com>; Jeffrey D Boyer <jeffrey.d.bo...@jci.com> Cc: yocto@yoctoproject.org Subject: Re: [yocto] Mounting USB drives on a "read-only-rootfs" based system Yup, even mdev based images do that with current OE. I'd expect "/media" to symlink to "run/media" on most devices (regardless whether the rootfs is read-only or not). Check if that's the case on your system.
