Hi Jiming,
    It's ok with configure MrcInitTsegSize = 8M.I can boot ubuntu and windows now ! But when I set MrcInitTsegSize = 8M, anthoer issue happened:we can't find mrc.cache which will cause a restart again in fspinit api when I restart the system(pci reset).
Thanks,
Tank

Hi, Tank,

 

It might be the TSEG size configuration.    

 

In devicetree.cb:     

    register "MrcInitTsegSize"      = "TSEG_SIZE_DEFAULT"

 

By default  TSEG_SIZE_DEFAULT is 0.   It needs to be set to none 0, such as 8  (TSEG_SIZE_8_MB).

 

Let us know if this helps.

 

Jiming
