Hi, gent:
We are testing suspend/resume on SK-TDA4VM.
System fails to `suspend to memory`.
We use the SD card image from TI website:
TDA4VM SD card image: 08.06.01.03 (31 May 2023)
The error message is as below:
Add extra kernel arguments in u-boot prompt for debugging:
| setenv optargs 'ignore_loglevel initcall_debug no_console_suspend' |

Do you have any ideas how to fix it?
