Hi.

DP screen output is no problem.

We checked the HDMI output in version 6 without problems.

We modified the file(app_cfg_mcu2_0.h) in the same way of version 7.

The 7 version has a problem that the screen display is not output.

Thanks in advance

* EVM Board Model : J721EXCP01EVM

* S/W version : Processor SDK RTOS Automotive (PSDKRA) v07.00.00.11

Hi hojon

I am sorry i did not get the question.

Do you means display not working for DP output? or for HDMI output?

Hi brown son,

Can you please check if API appDssConfigureBoard in the file vision_apps\utils\dss\src\app_dss_j721e.c is getting called?

Was HDMI output working fine on SDK6.2?

Hi.

In 6.2 version, the HDMI output is visible on the screen.

This is an option setting.

Thank you.
