Hi,
Reference: 2.5. System Suspend Mode Workarounds — Linux SDK for AM62L Documentation
Using the device tree k3-am62l3-evm-lpmdemo.dtb, executing the command "echo mem > /sys/power/state" fails to wake up via the WakeUp button. Even after modifying uint32_t mode = 6 in plat/ti/k3/common/am62l_psci.c, wakeup is still unsuccessful.
