P1022 System Version Register shows wrong value

Hi all,

 

We are using P1022 on our board.

However, U-Boot recognize only one core instead of two. And the System Version Register indicates that it is neither P1022 nor P1013 processor.

U-boot=> md 0xff7e00a0 2

     ff7e00a0: 80211151 80ee0111

From the P1022RM chapter 26.4.21, it says:

System version numbers for the chip system logic
0x80EE_0011 P1022 with security, dual core
0x80E6_0011 P1022 without security, dual core
0x80EF_0011 P1013 with security, single core
0x80E7_0011 P1013 without security, single core

 

Can someone explain me what may happens here? The value of SVR is read-only and is hard coded by Freescale, right?

 

Thanks for any advise,

Check that the processor connection is performed in accordance with requirements of the AN4343 and P1022EC.
