TDA4VH-Q1: Test the lockstep mode of MCU1-0 and MCU1-1 of TDA4VH on J784S4XEVM

I mean，i want to Boot and run Mcu Island MCU_R5Fs app in lockstep mode from SBL。if J784S4XEVM supports this test？

Hi,

Please reference: 5.2. J784S4 SBL — Platform Development Kit (PDK) - J784S4 User Guide (ti.com), and try suggested changes there.

Hi

   The content of your reply is the SBL on MCU1_0 in split mode or lockstep mode.

   What I want to confirm is that the APP on the MCU1_0 is running lockstep mode.

   The flow of the program is roughly as follows：

   SBL----   APP(lockstep mode)  ----  R5F(main domain)/A72

   Does J784S4XEVM support lockstep mode?

Hi,

The J784S4 EVM supports lockstep on the R5Fs.  

• "Lock (lockstep) mode: One main operating core with the other operating in lockstep

The TDA4VH TRM Section 6.3.2.5 R5FSS Lockstep Error Detection Logic, goes over R5FSS lockstep behavior.

Is there a corresponding Demo on SDK8.6?
