Small update…
Application was still running without crash after 3 days.
I got a bit worried….. I am sure the system is not stable, but appearantly I changed some detail such that the time to crash got extended.
Yesterday I restarted the application without serial read. In parallel I used a dedicated “crash program”. It reads the serial-over-usb with a buffer of only 2 bytes. That gave me 23500 reads/minute versus about 120 per minute with my applictqion. On top of that I fire an interrupt every 100us.
Bingo.. crash after 14 hours. It’s still not stable
@rich..
I had hard wired terminal with gui up. However ist completely frozen. Control-alt-F1 or control-alt-F2 does nothing. So… no messages…
Today i spent time to hardware-built-in the terminal. So far it was blocking the hallway. I mounted it at the inside of the hallway cupboard. Made the keyboard “foldable”. This allows the terminal to be a permanent service setup. So…. No Kernel testing today. That will be tomorrow.
I was able to compile and built a kernel from source on my second system. It took about 3 hours.
I also compiled all modules. That took about 36 hours. Completely unnecessary as I only need the usb-serial module which I probably better compile als part of the kernel anyways.
But… I’m learning……
