FW: IMX8QM dpu demo question

Hi,

 

I’m having some trouble to work for Display output from M4 core1 on my IMX8QM MEK. I run the character unit demo from the SDK_2_9_0_MEK-MIMX8QM:

PATH : /SDK_2_9_0_MEK-MIMX8QM/boards/mekmimx8qm/driver_examples/dpu/character/cm4_core1

Monitor is connected thru an external LVDS - HDMI adapter.

 

I have been able to run the demo code with qpsi mode (use ../cm4_core1/armgcc/build_flash_debug.sh) and it works, but when I run the same procedure with emmc mode (use ../cm4_core1/armgcc/build_release.sh), it seems to lock up in the SOC_InitDpuInterrupt().

Would you be able to describe a step by step instruction on how to make the dpu character demo program run successfully with emmc mode on IMX8QM MEK?

Hi Yin,

Within the readme of the SDK you can find the description of the operation.

Regards
