S32K148 JLINK debug error

[YiWang]

Until yesterday, I was able to debug flash by Jlink using S32DS, but today I can’t flash using a new program.

In the S32DS, “Break at address” 0xdeadbeee “with no debug information available, or outside of program code.” Is displayed, and when I open Diassembly, I get a lot of error messages.

How can I use S32DS to debug flash in S32K148 via JLINK again?

The console imformation is shown as follows:

Hi @YiWang 

Do you have another compatible debugger you can use to try to flash again? I want to discard a broken connection.

Best Regards!

HI  JRoberto

I have tried several debuggers,however, I cannot debug flash. All of them show same result.

“Break at address” 0xdeadbeee “with no debug information available, or outside of program code.” 

I doubt that maybe the program in flash causes immediate Hardfault, which prevents the JLink from communicating properly. 

[JRoberto]

we can check the signal behavior from the pin "RESET_b".

Do you have a way to capture it?
