"TrustZone_Cortex-A9AC6" example does not run normally

Hi Mohammed_lami

Sorry that I am not familiar with the DS licensing limitation.

However you can find my response to question 4 ,5 & 6 below:

4) The hardware that I use is ARM Cyclone V SoC Development Kit; if you recheck the error message that I sent in my last post "! Bus error on memory operation.", does this message mean that the problem in the bus between the memory and the A9 core not the memory itself? If so, which factors may affect that bus, is it possible to investigate this point please?

I do not think it is a problem between the memory and A9 core. The error is due to it is trying to access an invalid memory address.

5) Regarding the ARM Cyclone V SoC Development Kit, it has different jumpers and dip switches that configure different things of the board, is the dip switch configuration that may affect such problem? For example, there are switches that determine the boot type.

You could find the switches state from the document here

The boot type you are referring to is to determine the boot source for the board. (ie sdcard, qspi)

6) When I power on the board, the LCD on it shows "No IP address is obtained" and "Hello Tim!" messages in two lines, isn't that mean Linux operation system has been loaded? If so, do you think this is normal?

It seems like the linux operating system is loaded. It is not normal.

When you flash the example image did you also flash the pre-loader too?

I would suggest trying out the example in the document on bare metal:
