Unable to halt processor Arm cortex M3 more

I am currently working with the evaluation board TLE9879 Evalkit V1.4, which utilizes an Arm Cortex M3 core.

Initially, I encountered no issues with halting the processor. I employed SWD to write into the DHCSR register with a value of 0xA05F0003, which successfully halted the processor. Upon re-reading, the register returned 0x010B0003 (halted state).

However, a recent development has presented a challenge. After running an application that may have introduced an error, I am unable to halt the processor. When I attempt to write into the DHCSR register with the same value of 0xA05F0003, it now returns 0x01090003 (not halted).

I would greatly appreciate any insights or advice regarding the possible reasons for this change in behavior.

Thank you in advance for your assistance.

Best regards,
Mario
