I am using the S32K388 board with Lauterbach as external debugger. Frequently, the Lauterbach drops the connection to the board.
As described in the document S32K388EVB-Q289 HWUM (Chapter 15.2), the necessary hardware changes have been implemented (e.g., J822, J848 disconnected, R43, R161, R181, R192 depopulated). The schematic and board revisions are:
- Schematic - SCH-88925 REV B
- Layout - 700-88925-REV X1
(I do not experience any problems when using the PEMicro debug probe together with the S32DS.)
Hi@DirkEtzler
I cannot reproduce your problem;
I've run several tests on my device and haven't found any issues.
I suggest you contact Lauterbach's technical support for assistance.
Hi @Senlent,
thanks for the quick check. I can reproduce the issue more frequently, when I am trying to reset the board through the Lauterbach (e.g., SYStem.Reset or similar). Do you mind checking this for me on your board as well?
As a side note-I have not experienced or noticed any issues with the S32Z2 (S32Z270-DC) evaluation board I am using.

Sure, here is my test and you can see it work well.
This is a discussion and troubleshooting guide for a similar problem that I saw on the Lauterbach forum. You can refer to it.
