Caveat: I'm an embedded veteran, but a first-time beagle-bone user. (Purchased from Arrow)
I'm having this problem that I can bring up my Blue using Cloud-9 and things go great for a while. Then, after a variable amount of time 10-30 minutes, the file system seems to switch to read-only. I have connected to wifi and got my feet wet using online instructions, and to bring up StrawsonDesigns Robotics cape. My first sign of trouble was that the Blue went unresponsive on Cloud 9, because it can't write to: /var/lib/cloud9/.c9/state.settings [image: ReadOnlyError2.jpg] So, I did some research and could not find anyone else reporting this issue lately. So in true nerd form, I tried again several different ways. My initial efforts had been using the built-in flash, so I spun up a new bootable micro SD card and I was back up and running again. The first time the system went rogue it was during. an apt-get update attempt. So I naturally tried again. Same result.. the update failed part way through with read only errors. So I tried again, spun up a new SD card and this time I did not do the update. I cloned the StrawsonDesigns code base and was experimenting again (just running the examples) and after a while I started getting read only file system issues again. My next attempt at fixing the problem was to install a new eMMC image on the board itself. This went fine and I was back up and running again. I experimented with the robotics cape code for a while, and then left the Blue running on my desk. I came back 30 min later, and my FS was read-only again. I think I've considered most things I'm doing and can't figure out the problem. I'm looking for help. - I'm running on USB power from a high-end powered USB hub - Once the FS goes read-only I can still log in through the wi-fi connection and run shell commands that do not need to write to files - I have yet to write a single script or line of code, so I don't think I'm causing the problem. - The same problem occurs on internal or external drives. - I'm not filling up the drive or anything like that df -h Filesystem Size Used Avail Use% Mounted on udev 215M 0 215M 0% /dev tmpfs 49M 5.2M 44M 11% /run /dev/mmcblk1p1 3.5G 1.9G 1.5G 57% / tmpfs 242M 0 242M 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 242M 0 242M 0% /sys/fs/cgroup tmpfs 49M 0 49M 0% /run/user/1000 Kernel: 4.19.94-ti-r42 BeagleBoard.org Debian Buster IoT Image 2020-04-06 Debian: 10.3 Currently running on a: MODEL_BB_BLUE Robot Control library Version: 1.0.4 Any suggestions???
