Does wp7605 have an auto suspend mechanism? Because only the debug console is connected, it seems that there will be no response due to entering suspend (dmesg message is as follows) [ 64.408601] Freezing of tasks aborted after 0.008 seconds [ 64.503073] Freezing of tasks aborted after 0.009 …

there is rollback mechanism. If within the probation period after boot up , you reset too many times, the system will rollback to previous version. You can use “update -g” to mark the system as good system to avoid system rolling back.

If you remove usb cable from pc, it will enter sleep mode, after that the uart console will not have response

We found that some target boards after installing the wake program(we have mark good with command "update -g "), I still have the problem of missing the app after rebooting several times, causing the system to enter sleep mode. Is there any way to solve it?

how about using the command below in init script instead of application? echo NO_SLEEP > /sys/power/wake_lock Or you can build the wake up application in the legato cwe, this can avoid application disappeared in the field. e.g. [image]
