Other Parts Discussed in Thread: AM62A7,
Tool/software:
Hi,
I am using AM62A7 with PROCESSOR-SDK-AM62A 9.2 version.
Currently, when system is kept for continuous sleep wake test (My wakeup source is a PIR sensor connected to SOC GPIO), At initial 3-4 hours, the system is working smooth. But after this time (sometimes after 17hrs also), I am getting the following error continuously printing in the debug console for every 5 seconds.
I am having terminal session running but I can't even run any other commands.
[ 5681.334371] rcu: INFO: rcu_preempt detected stalls on CPUs/tasks: [ 5681.340483] rcu: 0-....: (104 ticks this GP) idle=1c54/0/0x3 softirq=186031/186032 fqs=202775 [ 5681.349084] (detected by 2, t=1014216 jiffies, g=304073, q=566113 ncpus=4) [ 5681.356035] Task dump for CPU 0: [ 5681.359254] task:swapper/0 state:R running task stack:0 pid:0 ppid:0 flags:0x0000000a [ 5681.369157] Call trace: [ 5681.371596] __switch_to+0xd4/0x130 [ 5681.375087] 0xffedf80c
By searching on the internet, I got to know that __switch_to function is from processor for context switching between two processes. Can you confirm is this the issue? and guide for the debugging of this issue.
