The device uses 2G IM DDR3. I use fsl-yocto-L4.1.15_2.0.0-ga BSP(Yocto 2.1) to bring up the device.
When I type "ifconfig eth0 down" and "ifconfig eth1 down" to disable all the Ethernet modules, the system crashed.
The files in the attached file include the debug log file and the file that modifies the debug message.
It appears in the debug log file that when it enters the low power mode, the DDR clock frequency changes from 533 MHZ to 24 MHZ. The system is still alive.
However, when the low power mode is changed to normal mode, the DDR clock frequency is changed from 24 MHZ to 533 MHZ. At this point, the system will hang.
Can you help me to solve this issue?
