No answer in Serial Download mode

Hello everybody!


I am trying to download a hex-file to an Eval-ADUCM350EBZ Rev. 0 using CM3WSD.

It does not work.

I hooked up my scope to the testpoints T75 and T76 of the board (TX and RX).

I can clearly see the 0x08 sent by the CM3WSD but there is no answer from the ADuCM350.

T75 is kept steady at + 3.3 V.

Power supplies seem to be OK.

I tried to switch M1 and M2 to position B, but this did not help.

Of course I pressed SD and pulsed reset.


What else can I check?


Kind regards,
