I have a hard time to program STM32H7B3I-DK from Keil MDK

[bojankoce]

Hello guys.

As indicated in the title, I have an STM32H7B3I-DK board here with me. I am trying to play with it but currently having a hard time to load the code to the board from Keil MDK v5.23. When I compile the project and press a Download button, I get Internal Command error as indicated bellow:

ST-Link Debugger is selected for Debugger in Keil uVision project:

Also, I used ST-Link Upgrade to upgrade ST-Link firmware to the latest version. The board seems to be functional because I can connect to it and program it using STM32CubeProgrammer but not with Keil MDK.

Do you have any idea what I might be doing wrong?

I used Keil MDK with Nucleo-F401RE board without any problem.

Thanks in advance for your time and efforts.

Sincerely,

Bojan.

>>Keil MDK v5.23

VERY OLD

Get 5.29, use the ST-LINK drivers, DLLs and support from that. This board uses an ST-LINK V3, you need software that is sufficiently aware of this.

\KEIL\ARM\STLINK

STLinkUSBDriver.DLL

ST-LINKIII-KEIL_SWO.DLL

Hey, @Community member​ !

Thanks for your reply. With Keil v5.30 it is working like a charm! :)

Cheers,
