My current situation is this:
. I am configuring a BBAI64 to do some work
. The image that fits my need is the “minimal” image
. There isn’t a reccommended “minimal”, only a reccomendend “IoT” for BBAI64 at the moment
=> I installed the latest “minimal” available and then i upgraded frequently, at the moment my kernel is “5.10.120-ti-arm64-r61”.
. PROBLEM. The kernels i tried so far a far too instable for my use, they crash very often.
. Q1. Do you know any reasonably stable kernel for the BBAI64, may be the one one the reccomendd “IoT” image ?
. Q2. If we have a quite stable kernel is there a procedure to downgrade it or do i simply follow the same procedure for a debian box ?
The best you can hope for is to wait for kernel updates that fix the crashes, assuming it is a software issue, or an issue that can be fixed by software.
If it is a particular kernel driver that is crashing, then assuming it is not needed in your use case, you could try removing it by creating a devicetree overlay to disable the modules, or you could just remove the kernel module (assuming it is not statically compiled in)
Are you using a good power supply ?
Are you using a fan ? The processor does get hot, and even though it is automotive rated, I do not know about other parts on the board. Especially the RAM.
I haven’t seen many posts here about system crashes, apart from yours, but then I don’t know how many people out there are actually using these boards. They are still very new.
It might be worth checking the TI forums (if any) to see if any of their customers are having issues with the TDA4VM EVM boards crashing.
Oh, for the moment i do very little, oftent just
. login via serial console
. login via SSH (from on usb-ethernet)
Then, i leave the system like that, say a for a few hours and when
i go back to it crashed.
I realize the best is new so i figure there will be some time before the kernel
will be stable enough.
Sadly, we have found over the years, this is just not 24/7 stable. (BeagleBone Black, PocketBeagle, etc…) Random OS’s (Looking at you specially Windows) like to put the usb hub to sleep, which reset’s the board plugged in…
While the one cable setup is useful for debugging and development.
For any long time usage, you really need to add external power source.
I spoke too fast.
Today I turned it on, with power supply, after say 20 minutes, it crashed.
I was doing nothing, just serial connection open waiting for crashes.
I will try with a recommended image and let you know
I want to inform anybody who will read this thread in the future that, at the time of Jan-2023, with kernel 5.10.153-ti-arm64-r86, everything seems working fine, system up since 2 days powered via USB. bye
