Chronos User Discussion / mSATA USB Enclosure, not recognized.

« on: January 02, 2020, 03:36:12 PM »

I had an mSATA drive laying around and I thought I might get better saving speeds from my Chronos. When I plug the drive in it is not recognized by the camera. All of my conventional USB drives are recognized just fine (from 16gb to 128gb in size).

The Chronos is running the latest firmware v0.3.2-patch1. The drive is an mSATA, Samsung 860 EVO, 250gb. The enclosure is an HD6011-1s (Amazon, eBay, Alli), its based around the JMS578  USB 3.0 to SATA 6.0Gb/s Bridge Controller.

I tried formatting the drive to both FAT32 and EXT3, I also tried making the partition smaller (120gb) with the same results.

If anyone has any ideas as to what I can test or check next I would very much appreciate it.

Software Dev / Question about SD card wear.

« on: June 14, 2019, 11:02:37 AM »

Does the OS SD card get written to constantly while the camera is running? I had an SD card fail in a weird way and I'm not sure if its Raspberry Pi syndrome or just a bad card.

For reference it's not the card that came with the camera its a Kingston 8gb which is slightly smaller than the original card. To get the Chronos OS onto the card I had to shrink the ROOTFS partition by a little sometime around v0.2 and I have been updating normally since then.

Software Dev / Saved file's owner/group/permissions.

« on: March 16, 2019, 04:15:18 PM »

I am using ext3 so I can save >4gb files but the permissions made by the camera are pretty wonky. Is there a way (even if it's a one off change I need to make to my own camera) so that I can change the user and group that the files are saved under? I'm reasonably familiar with Linux and don't mind making backups of my OS microSD in case I brick something.

If there is no easy way then no worries.

Thanks for your awesome work!

Software Dev / "Missing" the out point when saving.

« on: June 23, 2017, 01:08:45 PM »

When saving files I have had the camera miss the Mark Out point a couple of times.

I set my in and out, set 30fps for the output file frame rate and then hit save, the camera goes through its saving sequence but it passes the Mark Out point and if I am not paying attention it will wrap around back to the beginning of the recording (see image below). Aborting after the camera has passed the out point causes it to become unresponsive (I haven't caught it before wrapping around yet), powering off then on gets it going again. The saved file is unplayable in VLC  (I haven't tried any creative methods of extracting frames).

Has any one else seen this behavior?
