How to check if SEC is avaible ?

Hi,

I have an LS1043ARDB board, with PLS1043ASE7QQB mounted on it.

Datasheet says that  'E' is in the part name means that SEC is available into the SoC.

However, on NXP product information page (here), SEC is not present whereas it is there for other products with 'E'.

Hence some quetions ?

Is SEC available in proto SoC ?

Is there a quick way to check if SEC is inside the SoC ?

Kind regards

Pierre

The PLS1043ASE7QQB has SEC.

Use U-Boot to read the DCFG_CCSR_SVR value and check the VAR_PER field value - refer to the QorIQ LS1043A Reference Manual, 13.3.10 System Version Register (DCFG_CCSR_SVR).

You're right, but I wanted to point out that SEC in not written in the short description on the chip, for example in 'buy/parametric' tab

However, thanks for the finding about the register, it helped.
