ST-Link and J-Link not work well with STM32F745VEH6

[Kenji1]

Hi team I have a problem on debugging STM32F745VEH6 with SEGGER J-link and ST-Link V3. And phenomenon is different on both debugger.

My enviroment:

STMCubeIDE Ver.1.8.0

Debbuger: ST-Link V3/V2 and SEGGER J-Link Ultra +

MCU: STM32F745VEH6

With ST-Link V2:

Works fine.​

With ST-Link V3:

After download program, go to HardFaul_Handler function and crash.

There is a data mismatch address error when download the code.

With J-Link:

Program can download. But live expression and expression not work.

Variable does not update when write it.

When the debugger is detached, the value is updated.

 With ST-Link and STM32CubrProgrammer:

Both version of ST-Link outputs DEV_TARGET_RESET_ERR error.

 With J-Link and J-Flash app:

Connection is fine.

What could be the cause? And how can I solve it?

Hello, I'm having a very similar problem with STM32G070 and CubeIDE V1.8.0.

Using ST Link V2 I can download the program and it shows as verified correctly, however, I cannot use Live Expressions. All of the values show up as 0.

This is somewhat intermittent. I can debug on a board that had a crucial circuit (unrelated to the MCU) ruined during hardware debugging. I've now tried it on two new and identical boards and they will not cooperate with Live Expressions.
