Activate snvs on ls1021atwr

[letailleurjerom]

hi all,

I work on ls1021atwr with cpld V2.0.

I work in secure world and I would like to use the snvs device.

I have a imx snvs inplémentation but does not work with ls1021atwr.

Do you need to activate a special clock?

Do you have a snvs implémentation guide?

 thanks for you help.

Best Regards.

Hello letailleur jerome,

Please refer to secure boot section from "Submit Form ".

SNVS is security monitor block, you could refer to the section "Security monitor" in LS1021A Reference user manual for details.

Please refer to the following to setup the board for secure boot flow.

a. Flow A
Program the ITS fuse. Use RCW with SB_EN=0
Or
b. Flow B
For prototyping phase, don't blow the ITS fuse, but use rcw with SB_EN = 1.

Have a great day,
TIC
