IAR EWARM Unknown or ambiguous symbol __probeCmd in .dmac file
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.
