PROCESSOR-SDK-J784S4: Minimal device tree for J784S4 on SDK 10.0

Dušan Stanišić

Tool/software:

Hello everyone,

We are currently preparing the SDK for a custom board based on the J784S4 and would appreciate guidance on the minimal device tree changes required for this board in SDK 10.0.

We followed the instructions outlined in the Custom Board Bring Up Guide, particularly section 4, but the provided link appears to be non-functional.

Could you please provide the necessary updates or point us to the correct resources?

Regards,

Dušan

Hi Dušan,

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1047411/faq-tda4vm-is-there-a-custom-board-bring-up-guide

This is the E2E.

Somehow there is a space in the App note. I will try to fix that.

Hi Keethy,

I noticed that some of the changes are present in the DTS files within both the Linux and U-Boot sections of the SDK. Could you clarify where these changes should be applied? Should they be adopted in one, the other, or both?

Best regards,
Dušan

Hello Dušan,

R5 SPL, A72 SPL, A72 U-Boot, A72 Linux. All of them have separate dts files & optimizations need to be done at each phase.
