Hello,

 

I am facing an issue concerning the boot in SMP mode of the kernel 3.12.37-rt51 from SDK 1.8 on P2041 v2.0.

This is the full CPU release :

 

CPU0: P2041E, Version: 2.0, (0x82180120)

Core: E500MC, Version: 3.2, (0x80230032)

 

In UP mode by passing this parameter "nosmp" in the bootargs the kernel on this platform boot up easily.

Furthermore, with this cpu release and with the same linux kernel it boot up in UP and SMP mode:

 

CPU0: P2041E, Version: 1.1, (0x82180111)

Core: E500MC, Version: 2.2, (0x80230022)

 

The u-boot applied these errata :

 

VX3240> errata

Work-around for Erratum CPU-A011 enabled

Work-around for Erratum CPU-A003999 enabled

Work-around for Erratum DDR-A003473 enabled

Work-around for Erratum ESDHC111 enabled

Work-around for Erratum A004510 enabled

Work-around for Erratum A004849 is not enabled

 

Thanks for help

Benoit
