on VEX IQ Gen2, We have few instance of “Brain freeze”
where X button on the brain does not do anything.
controller does not do anything.
the only thing we can do is to unplug battery.
We are not sure it is the brain-mailfunctioning?
Is it the code? if it is the code, is there an example of a code to “freeze” the brain?
code can cause the brain to freeze, generally that would not be the case with blocks code, more likely with C++ when a program overwrites system memory for some reason.
This could be the cause if it also happens when user programs are not running, usually hardware failure involving flash memory.
If the X button is not responding it’s likely other features will stop working as well, perhaps the program run time display or radio scan indicator.
We have had this happen a few times recently on a gen 1 brain, the only solution is to pop the battery out. This is an ES team using blocks only. I don’t recall if the brain this was happening on was on 2.2.0 or 2.2.1
Thanks very much for the reply.
we are using C++ but at very basic level, nothing to deal with pointer/system memory.
the most complicated thing we did in the code is start and stop the mulitple thread.
what would you suggest us to do troubleshoot this issue?
