Hello,

Thank you for your inquiry.
Such an issue is not known to us.
Could you try debugging your project using Ozone? segger.com/products/development-tools/ozone-j-link-debugger/
When setting up Eclipse did you follow the recommended config steps from our Website? segger.com/products/debug-prob…/technology/ides/eclipse/

Best regards,

I succeed to debug another application with Another tool, so it is not a hardware problem.
An yes I tried to follow the recommended config steps from your Website.

I still have

ERROR: Can not read register 0 (R0) while CPU is running
and
WARNING: Failed to read memory @ address 0x00000000

In disassembly view:

00000000: Failed to execute MI command:
-data-disassemble -s 0 -e 60 -- 3
Error message from debugger back end:
Cannot access memory at address 0x0
