Hello @tpeng.1​ ,

Can you please try to upgrade the STLink Firmware and then tell me if this resolve the issue ?

It may be the cause of this problem is on the configuration. I suggest you to share the option bytes settings?

Please kepp us about your update.

Hi Imen,
I can program elf file to Nucleo-144 board with STM32CubeProgrammer, but I still can not debug it with IDE.

Hi @tpeng.1​ ,

Can you please try with the following option bytes:

• TZEN=1 (TrustZone-enabled device)
• DBANK=1 (Dual bank Flash configuration)
• SECWM1_PSTRT=0x0 SECWM1_PEND=0x7F
• SECWM2_PSTRT=0x1 SECWM2_PEND=0x0

Hi Imen,

Thank your help.

The option byte values given from you is the same as the my board settings.

I uncheck the “Verify flash down�? in IDE debug tab.  File download complete. When viewing disassembly,

fffffffe:  Failed to execute MI command:

         -data-disassemble -s 4294967294 -e 4294967434 -- 3

         Error message from debugger back end:

         Cannot access memory at address 0xfffffffe

ffffffff:  Failed to execute MI command:
