Update: when I set the TPS65217 to go in SLEEP mode, by setting bit 7 of reg 0x0A, after the poweroff command the TPS65217 actually goes in sleep mode and does not start again. Summarizing: a) poweroff command + ethernet cable -> there is a real poweroff and the system goes off b) poweroff command but no ethernet cable -> the system switches off and the switches on again c) poweroff command, no ethernet cable + TPS65217 set in sleep mode -> the ARM switches of and the TPS65217 goes in SLEEP mode.
It looks like, when the TPS65217 goes off (and ethernet is not plugged), it receives a wake-up signal and starts again but if it goes in SLEEP mode, it does not receive it. I am really confused about this behaviour. Hoping someone already saw that and there is a solution. Cheers.
