Segger J-Link not flashing during debugging - S32 DS 2018 R1

[andyknitt]

I'm using S32 Design Studio for ARM 2018 R1 on Windows with a Segger J-Link for debugging.  This had been working fine until I installed the latest J-Link software pack (7.66d for Windows 64 bit) so that I could use J-Flash independently of S32 DS.

How when I attempt to debug, it will work if I have previously flashed the S32K142 with my debug application using J-Flash (outside of S32 DS).  However, S32 DS won't flash the part.  The J-Flash popup that I've gotten when I start a debug session in the past no longer appears.  

Console output is listed below.  Any advice on how to get flashing working again within S32 DS would be appreciated.

Thanks,

Andy

Hi @andyknitt,

This sounds like some conflict between versions of Segger J-Link SW. It could be the newer install overwrote the old one or maybe just some shared files and broke the older SW.

My suggestions are:

1) Uninstall the new SW and see if the debugger works again.

2) Install S32 Design Studio again, to a new folder location (you can install it multiple times, just gets hard to manage which one to use) and check if the new install works.

3) Contact Segger about this. It's their SW.

Hope that helps,

Mike
