Software Dev / Re: Chronos V0.4.0 Beta - Debian and Networking
« on: April 12, 2020, 10:02:00 AM »
Every time I upgrade the firmware/OS I make an image of the SD card in case something goes wrong. So far I haven't had any problems swapping between versions. My most recent roll back was from 0.4.0b + online updates (about 40 or so) back to 0.4.0b with no updates, I didn't run into any problems. Previous to that I went between the 0.1 0.2 and 0.3 with no particular issues.

try focusing a camera at 1280x96 to see how fun this can be

I usually set the camera to 128x128, focus then to back to the crazy aspect ratio. Just sayin.

It seems pretty quick. On the playback previous recordings section I never see any recordings and the %used is wonky but that doesn't break functionality by any means.

Do you have a readme for the network menu on the new UI? First thing it did was ask me to set a pw without saying what it was for. Will it change the root pw used for ssh?

Awesome! The new UI is great, even with the menu order being a little wonky, I was able to find all the setting I'm familiar with.
Update over network is also great, it makes things painless. Being able to SSH into the camera also makes way easier to poke around.

I think this update delivered pretty much everything I was hoping for! Thanks guys!

Chronos User Discussion / Re: mSATA USB Enclosure, not recognized.
« on: March 12, 2020, 02:07:28 PM »
Update, in case some future person googles this.

I checked dmesg over SSH while plugging in my not-working mSata enclosure and a normal USB stick.
It seems like the camera doesn't recognize it as mass storage.

I will keep working on it, now that I have SSH access it should go much easier. Thanks Chronos Dev Team!

*EDIT*

Found a potential fix by disabling uas (USB attached scsi).

$rmmod uas

Then create a new file: /etc/modprobe.d/blacklist-uas.conf, with the line

blacklist uas

This doesn't seem to have broken anything, your mileage may vary, I'm not sure if the RW speeds will be affected.

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.

I bought the cheapest LED worklights from a hardware store and added filter capacitors to the driver's output. They now give a flicker free, cool light but have to be run from a reduced voltage. The designers take into account the 'off time' of the flicker in order to drive the LEDs brighter when they are on, applying full mains voltage runs the LEDs at ~1.4x their "rated" wattage.

I managed to recover all the files using a tool called PhotoRec.

TestDisk and PhotoRec are extremely powerful tools, I would recommend them 100% but if you have the hard drive space try to make an image of the SD/USB/SSD and do your recovery on the image. There's no telling if the storage device will fail permanently while you are halfway through the recovery.

I have the above mentioned lagging/stuttering issue as well as no video when using high gain at the max framerate. It's not a combination I am likely to use but I was checking it out of curiosity. I'll see if it is repeatable when I get some time.


Otherwise it looks and works great!

Software Dev / Re: Question about SD card wear.
« on: June 15, 2019, 06:41:37 AM »
It started having intermittent write errors. When trying to write an .img to the card it would fail at different places in the write (the same .img files wrote just fine to other cards).

I wasn't sure if it was from excessive writing when in use (RaspberryPi loves to do this) or if I had a garbage card. Looks like it was just a crap card.

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.

Ran the camera on an older version and everything looked fine, updated and found the same black calibration issues, so here's what I found.

#0 It only happens at frame rates above ~27kFPS
#1 It gets 10x worse at 4x analog gain, at 1x and 2x the image is pretty good. At 16x I get only gibberish for an image.
#2 The flickering seems to be related, it is most apparent when the vertical banding is present. I haven't measured the period of the flicker yet to see if it is the same at every resolution/fps.

Below I have attached 4 images taken at the 320x96 40420.4fps 20.08us 4x analog gain (worst case scenario but the effect is very similar down to ~27Kfps. I let the camera warm up (it seems to do that a lot faster now, the fan ran at full speed since the update) before taking the images. I had to convert them to PNG because the forum didn't like .TIFF files made by the camera.

0th image is taken before doing a black cal and before doing the factory cal.
1st image is after a black cal but before the factory cal
2nd image is after the factory cal but before doing new black cal
3rd image is after the factory cal and after a black cal

Hopefully this is helpful.
