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

[xxJaRxx]

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.

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.

Open the project properties in CubeIDE. What is the MCU shown there?

Pavel thank you so much!  It was empty - no MCU selected.  As soon as I selected the correct one it all worked perfectly!

Thank you, I have been struggling with this for days!

As it’s Riverdi’s board and Riverdi’s tutorial, you’d be best to contact Riverdi for support:

I contacted them on Thursday but have yet to receive a reply - I chased earlier.

I was hoping it might be a general STM32 / Cube IDE issue as opposed to something Riverdi specific… but we shall see
