Hi Rudolf,
I have tested S3 on m2v-mx_se. It works perfectly. Except following
situation.
As you know, there are two Dimms in m2v board. if I put 1 memory module
on it, S3 would work perfectly. If I put 2 memory module on both two
dimms. The coreboot cannot boot. it would stop at post_cache_as_ram()
function.
In the beginning, you read resume_backup_memory from
backup_resume()function. resume_backup_memory should be 0 when we booting.
However, it will change after calling disable_cache_as_ram_bsp()
function, and resume_backup_memory == 0xffffffff.
Then it will get into memcopy() function, which would stop booting.
If I am guessing right, you just put one memory module in your board for
your testing, right?
Best,
Fengwei
