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?
