  1. Reproduce information

  • suspend using cmd : sudo systemctl suspend

  • wake-up using gpio ctrl : power button gpio signal 2sec

  • sometimes suspend fail occurs before wake-up using gpio ctrl

How did you put your the device to suspend.
Could you try “sudo systemctl suspend” command.

10

I used “sudo systemctl suspend” like my description before.

  1. Reproduce information
  • suspend using cmd : sudo systemctl suspend
  • wake-up using gpio ctrl : power button gpio signal 2sec
  • sometimes suspend fail occurs before wake-up using gpio ctrl

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one. Thanks

Can you remove the IOs connected and try?
Also can you share which release branch you are using.
Please share the complete boot log
