Original question:

DRA77P: Display initialisation in IPU core

DRA77P: Display initialisation queries

Part Number: DRA77P

Hi,

I am working on vision SDK v3.07. I am running a hlos usecase to display video streams from null source to display via M4 core.

I have some doubt that,

  1. When the ipu firmwares are loaded what does actually takes place there ?
  2. When does display initialise ?
  3. Are they initialised only when apps.out is run ?

Regards,

Padmesh

    Hi Padmesh,

    1) IPU firmware loaded to memory with its resource tables.

    2) In normal boot case, display is initialized when apps.out is loaded, in early usecase, a chain is run from RTOS when firmwares are loaded which initializes display and shows the buffers.

    Thanks
