When im downloading and debugging my firmware to STM32G070 Nucleo board with IAR EWARM, im getting the following error message in the debug log, I tried researching about __probeCmd and .dmac files online, but couldn't gather any information.

Debug log

Im using ST-LINK onboard debugger connected via PC serial port for debugging and downloading. Even though this error appears i'm still able to download and debug the firmware without any issues. Have anyone encountered this issue.

    \$\begingroup\$ This appears to be some library hiccup with this "dmac" file, whatever that is. If it's a file provided by IAR, I'd poke their support about it. Seems related to the specific in-circuit debugger. Missing drivers or whatever. \$\endgroup\$

Sorry, I don't have enough reputation to comment, so I add here that I have the same problem with IAR EWARM 8.32.4 and with the same .dmac file. Have you been able to manage it?

EDIT: after comparing the file with the version from preceding EWARM release 8.32.2, I figured out that the unwanted function _ExecDeviceSetup() has been wrongly added. Please remove exactly line interval 29-34 and line 36 (a matching }) and it will work.

    \$\begingroup\$ @simonstar you've added solution, which is good. But you left in the original "I am having same question", which confuses people. Please, edit this to make it into real answer. \$\endgroup\$

    \$\begingroup\$ The original problem was solved already. I don't think a realistic answer to the problem is to reinstall something which you don't have yet, or must wait and buy when it is available. \$\endgroup\$
