Chronos User Discussion / Re: 1.4 Boot problem

« on: May 29, 2020, 03:31:18 PM »

Hi everyone,

Thanks for adding details. After some information gathering about when/how this shutdown issue occurs, I've started the process of narrowing the problem down to something we changed in code between 0.3.1 and 0.3.2. For those encountering this issue who need to have their cameras turn on and work reliably until we release a fix, there are two options:

1. Attempt to use the "safe boot mode", which is a mode in which our power management controller ignores commands from the CPU, running only a minimal amount of firmware (your fan will spin at full speed, and no battery info will be reported on screen). To get into this mode, disconnect all power and battery, press and hold the power button down, insert the battery. If you see a green/red blinking pattern, it is now in safe boot mode, and you can attempt to use it normally.

2. Back up calibration data and downgrade to 0.3.1 using this downgrade package: http://forum.krontech.ca/index.php?action=dlattach;topic=460.0;attach=575


I apologise for the inconveniences that this might have caused. It has been something that has slipped through our standard QA process, but it is now a high priority for us to address.

Another thing that would help me out here: If you have software version 0.4.0, you should see a "Last Shutdown Reason" readout in the Util -> About section.

I had implemented this in mid-march to help track down the shutdown issue in the field, since it's been hard for us to replicate here in the office. On the first successful boot after a failed attempt, the software will have captured flags from the power manager and put them in this screen. It would be very helpful to know what this says the next time the issue is encountered.

Hi clkdiv,

Sorry for any inconvenience that may have caused. Do you remember approximately how many frames you had attempted to save?

I have a similar thought about it as you do.. Clicking "Safely Remove" in Play->Settings would have made the proper calls to the OS to first flush any pending buffers to disk before removal. While the chances of a save not occurring without first doing this are slim, it is still a possibility.

We do still have the recorded clip review screen in our software engineering task backlog, but I anticipate it to be a fairly lengthy undertaking to implement into the video system, so I can't promise a timeline for now.

Quick question for everyone that this is happening to: Does it happen on Battery, AC, or AC + Battery?

Thank you for your feedback regarding improvements to our frame timing.

Regarding the remote control of the camera via various methods:

• The Chronos doesn't run a windowing system like X11, both the video feed and the Qt GUI are directly rendered to the frambuffer in this case.
• We're a few weeks out from another release that should contain trigger config settings on the webpage that should work for most users' needs. Do you mind me asking what your triggering requirements are like for your setup?
• For the time being, the best way to handle remote triggering would be with your own calls to our Python API here: https://github.com/krontech/pychronos#io-group (while also acknowledging that it takes some time and effort to work with our API)

Thanks for the info. From a quick look at the TP link website, I see that their 300 Mbps Wireless router has LAN ports that operate at 10/100 Mbps speeds. https://www.tp-link.com/ca/home-networking/wifi-router/tl-wr841n/#specifications

The best way to work around the issue of the camera not wanting to boot when connected to the router would be to use a gigabit (10/100/1000) switch. Apologies for any inconveniences here. I'm working to find a possible fix, but it will likely take a few weeks before an update is available.

Hi ieSe, sorry the for late reply on this one.

Just wondering what the speed of your networking equipment is?

We've noticed a bug that stops the display from initializing correctly due to how the SoC in the camera currently handles networking initialization on 10/100 Mbps equipment.

It is not an issue on Gigabit equipment, and we are looking into it to determine if there's a fix.

Here's a tutorial that we just released this morning on how to utilize network control: https://www.krontech.ca/wp-content/uploads/2020/03/Network-Control-v0.6.5.pdf
