AM69A: Secure boot for AM69A

Hi,

You can refer to the following FAQ and userguide -

•  [FAQ] TDA4AL-Q1: Boot Flow Options on TDA4 devices 

• https://docs.u-boot.org/en/latest/board/ti/k3.html

Hi Le,

I saw that there is Secure Boot documentation for AM62, AM67

What documentation are you referring to here when you mention AM62 and AM67?

The Linux SDK documentation and the U-Boot documentation is all from the same baseline, so if you are referring to a U-Boot documention, you will be able to find the exact same information from the equivalent AM69A Linux SDK documentation.

Do you have documentation for AM69?

The AM69 boot is the same as J784S4 boot. You can also refer specifically to the J784S4 and AM69 Platforms section of the U-Boot documentation from the previous link shared by Josiitaa.

Hi Le,

The Link you provided is the AM62 Academy documentation, which is similar material to the SDK documentation. 

There is no exact equivalent sections in the AM69 Academy documentation, it only has the Security Overview section:

https://dev.ti.com/tirex/explore/node?node=A__AbgcdxCJ.d673wmE6LGhFg__AM69A-ACADEMY__vQtRUep__LATEST

Nevertheless, both the AM62 and AM69 are K3 devices, and follow the same high-level K3 Security Architecture.

Please look through the AM69A Linux SDK documentation link reference above, specifically the 1.1.7. Simplified SDK Build Using Top-Level Makefile section of the build details and the overall TI-SCI documentation (covers the Security core and is the same documentation for all SoCs)
