"TrustZone_Cortex-A9AC6" example does not run normally

Hi @JingyangTeh_Altera , many thanks for your response.

Yes, I used the debug configuration from the project it self.

The snapshots in your message didn't displayed (pls notice the snapshot below), this happened in Chrome and MS Edge browsers, can you please resend them (in word or pdf file) thanks a lot.

Hi @JingyangTeh_Altera , thanks for your support

Unfortunately, the problem still happening.

I have noticed the error messages in the commands view while debugging the project, I think there is a mismatch between the memory addresses in the scatter.scat files and the memory addresses of the board that I use (Altera cyclone V dev kit), and therefore the DS software couldn't find where is the memory on the board. Don't think this is the problem, if so, is it possible to modify the scatter files with the correct addresses? And what is the base RAM addresses for this kit?

Another point please, do you think that the dip switches of the kit may cause such problem, my board is initialized and the LCD displays a "No IP obtained" and "Hello Tim!" messages before I start debugging the project.

Thanks a lot for your support

Hi @JingyangTeh_Altera

Please take your time, and thanks for your support

BTW, the problem happens with other projects that suit my FPGA board (Cyclone V SoC FPGA development kit).

For example, same error messages appear with the "startup_Cortex-A9_AC6" project.

Thank you very much

Hi @JingyangTeh_Altera

Many thanks for your support

I followed the two documents that you shared and unfortunately multiple errors were generated, I think these documents belong to the old version of Development Studio (DS5), which is not applicable to the new version that I am using right now (21.1). Are there similar documents for the newer versions of the DS please?

However, it seems that I got a successful startup for the board in the supervisory mode (SVC), the "startup_Cortex-A9_AC6" has been cleaned and rebuild, without modifying the scatter file, then I debug it in FVP mode, all messages in the commands view were normal and the data was loaded successfully, please check the messages below.

The project was imported from the archived projects, I only exchanged the "C-code" in the "sort.c" file with a simpler one, the code should return the value of a variable, but after the successful startup and clicking on the the "run" button, nothing was displayed in the Target console or in the App console.

Anyway, I attached the "startup_Cortex-A9_AC6" project here (with the modified "sort.c" file), could you please check it for me, thanks again for your support.

Hi @JingyangTeh_Altera , thanks for your suggestion

I removed the vector portion in the scatter file according to your suggestion, but I got the errors shown below when I tried to build the project, any suggestion please?

Hi @JingyangTeh_Altera , thanks for your response

Actually, I tried to run it after shifting to 0x80000100, i.e. after 0x8000006C address, but the same problem happened at 0x80000106.

Please JingyangTeh, could you please confirm the following point:

1) The license that I am using was provided by the provider in the link below, and I think it is "silver license", is this type has some limitations that cause such problem?

https://www.mouser.co.uk/ProductDetail/Intel-Altera/ESW-DS-FIX?qs=GedFDFLaBXHRCPCuFYREfg%3D%3D#

2) The version of the Development Studio is Intel Edition 2021.1 as I mentioned previously, my license support only ARM compiler 6, is there some limitations come from the compiler?

3) I noticed that my license doesn't support the project that used ARMv8 instruction set architecture, it works with ARMv7 and below only, is there any issue with this point that can cause such problem?

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?

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.

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?

Please if you have any other advice and suggestions will be appreciated.

Hi @JingyangTeh_Altera , thanks for your response

Regarding your question "When you flash the example image did you also flash the pre-loader too?"

No, I don't flash the pre-loader, I usually only the files .axf file that generated after building the project.

The document you proposed, suggests in point 5 load the u-boot-spl.bin to the board:

This file is available only in the DS-5 and lower versions.

But it is not included in the DS Intel Edition 2021.1 that I use, it is really confusing! Any suggestion please? Why there is no documents for the newer versions of DS software?

hI @JingyangTeh_Altera

I tested all the solutions in my mind, available web documents and webpages and the solutions provided by your side, but the problem still exist.

What should I do in this case please?

Any other ideas please?

Hi @JingyangTeh_Altera , thanks for your response

I have bought the "ARM Cyclone V SoC FPGA development kit" and a licensed copy of Intel DS software, and I tested all the available bare metal examples but they were not working as I explained in details previously. Actually I don't have an idea about what's going on although I followed all your suggestions, if you need more data to let you understand the situation, please let me know. Alternatively, if there is another way to get support from Intel, please let me know.

Your support is appreciated
