Not able to get MCU target - issue using Riverdi EVE4 7" display and STM32CubeIDE

Hi all - first post here!

I’m trying get Riverdi’s LVGL demo working. This is the first time I have ever used STM32, LVGL and Cube IDE - so I’m hoping Riverdi’s video guide has just omitted something simple but crucial!

I’m using:

  • STM32 Cube IDE (v2.1.1)
  • ST-LINK V3SET (firmware version V3J17M10B6S1)
  • Riverdi development board (LINK)
  • Riverdi EVE4 7” display (LINK)

I’m following this video guide word for word and I have not done anything whatsoever over and above what is described in the video.
How to run LVGL on Riverdi EVE display - YouTube

The code seems to build successfully however when I try to debug/run I get the following error message (“not able to get mcu target”), which I assume is the crux of my problem.

I’d really appreciate some help getting over this (hopefully very simple hurdle) so I can start to familiarise myself with STM32 and LVGL.

Thanks,
James

Hi guys,

Bit of an update for clarification:

I can successfully connect to the ST-LINK V3 and the STM32 Evaluation board using STM32 Programmer, because I can read/update the firmware on the ST-LINK and I can read a bunch of IDs etc from the Evaluation board. However I still get the same “Not able to get mcu target” issue in Cube IDE when I try to debug or run.

Resolved! There was no MCU selected in settings:
