Re: Tiny Core v17.0 upgrade issues
Stefann:
I can no longer edit the previous post
but.. usb-serial-6.18.2-tinycore.tcz kernel extension now also works
for some reason the baudrate setting got lost
Its a bit strange because that is set on every start of my application and I did restart it multiple times
But anyways... It now runs
Thats probably an "application weakness"
ALL WORKS
and thanks for the reading & helping

Tinycore has a single command that handles that. It's called:
--- Code: ---update-everything
--- End code ---

That's right. Years ago we added a 30 minute time limit after
which you can no longer edit a post.
The issue was twofold:
1. When you post, it shows up as a new post. When you edit a post
someone already read, there is no obvious indication it was changed.
2. We had individuals changing information in posts that made replies
to that post look irrelevant.
If you need to update information, add a new post.
If you have an important correction, for example, a command line typo that will
cause the command to fail or do something bad, add a new post requesting it
be corrected and it will be handled.
Either way, readers will remain informed.

A...
I can now use some serious help....
As said in above posts, I succeeded to upgrade my Via eden 500MHz single core cpu 32bit system to TC17.
Everything works. But...
- After about 2 days it crashed. Application crashed, ssh crashed, VNC crashed. It's headless so the only thing I could do is a power cycle.
That "could have been a glitch"... but 2 days later it crashed again. I did just reboot as well.
Until last weekend the system did run on TC15. It could run multiple month without problem. In fact, I have not seen a crash since I started using TC 2 years ago.
So.... It very very very likely has something to do with the upgrade
(apart form TC17 this could also be human error or flash-card issues because I suddenly created big backup files).
The system runs my home automation.
- C program
- some PHP scripts
- some python scripts
- apache server
- vnc server (but currently no connected clients)
- samba
- ssh
- serial port over USB interface (with kernel extension)
Let's refer this as the "live system"
Apart from this system, I have a 2nd system that I use as a test setup. This system is a Via Eden 1GHz 2core cpu.
It's also upgrade to TC17. It already runs TC17 for some weeks without any glitch.
But..... it does not run the application.
Lets refer this to be the "test system"
I need to think of a clever plan to trouble shoot this:
- run the application on the "test system". It will not be able to connect to all peripherals but it will at least run code.
- step by step revert back the "live system". probably 1st run with TC17 core and vmlinuz but still non-upgraded applications.
any tips on how I can put logging in place?
- problem is that everything runs in ram. So I have zero diagnostics in case of a crash.
I probably have to connect a monitor ??? to give me some hint in case of crash?
Any other trouble shoot ideas?
(I'm not expecting anyone to have an idea on rootcause at this stage, just tips on how to approach this would be very helpful)

Yes, but your extensions are on persistent storage, right?
So send any log messages to /etc/sysconfig/tcedir/SomeFileName.log
Leee:
With everything running in RAM and you backups suddenly getting bigger, maybe you're running out of memory? Does the test system have more memory than the live system?
