PROCESSOR-SDK-J784S4: HSM TDA4VH: DFU issue

chang dou

Part Number: PROCESSOR-SDK-J784S4
Other Parts Discussed in Thread: TDA4VH

Tool/software:

I am working on the development of HSM TDA4VH bare board. When I tried to flash bootloaders (tiboot3, tispl, u boot) through DFU, I encountered an issue:

after successful flashing of tiboot3, DFU devices could not be found on the host.

It should be noted that tiboot3. bin is tiboot3-j784s4-hs-fs-evm.bin, and both tispl and u-boot. bin are provided by TI.

Hi Dou

Can you provide more information like Which SDK you are using?

Are you able to see any logs after loading tiboot3.bin?
