Facing Issue On Design Example: Intel Arria 10 FPGA Remote System Update via PCI Express*

[MIT_R_D]

Hi
I am trying to emulate the Design Example: Intel Arria 10 FPGA Remote System Update via PCI Express*.  i am facing issue when we trying to download any application
can anyone help me on this?

Steps Followed by me
Step. 1 : Load Mater_Image jic file through onboard blaster - Success 
Step 2: Reboot the dvk - Success - Four LED glows
Step 3: Copy driver, Install & run the driver - Success
Step 4: download application - Facing issue(PFA)

Thanks for the example design.

Hi,

Thank you for contacting Intel community.

Per my understanding, you are using design example from below?

https://fpgacloud.intel.com/devstore/platform/20.4.0/Pro/intel-arria-10-fpga-remote-system-update-via-pci-express/

Also,

If your design is sensitive to the PCIe boot-up requirement, Intel recommends that you do not use the direct-to-application feature.

Intel recommends that you set a fixed start address and never update the start address during user mode. You should only overwrite an existing application configuration image when you have a new application image. This is to avoid the factory configuration image to be erased unintentionally every time you update the start address.

Can you try this? Let me know your feedback.

Regards,

Aiman

Hi 
Thanks for your response.

Yes, I am using design example from below link

https://fpgacloud.intel.com/devstore/platform/20.4.0/Pro/intel-arria-10-fpga-remote-system-update-vi...

We are using same example design & driver.

"If your design is sensitive to the PCIe boot-up requirement, Intel recommends that you do not use the direct-to-application feature."

     - can u please help how to disable direct-to-application feature? 

Note: Configuration Mode is disabled from tool

"Intel recommends that you set a fixed start address and never update the start address during user mode"
       - Yes, we are not changing start address and trying to update only application image

"You should only overwrite an existing application configuration image when you have a new application image. This is to avoid the factory configuration image to be erased unintentionally every time you update the start address."
    - We are using master image jic file and updated through onboard blaster.
    - We try to replace the application image(either 1 or 2) by using same master image(ru_auto) rpd file. 

We are getting read back data error error after 100% Erase & Write Completed

Hi,

Apologize for my previous response, but I need some clarification below:

1. When following the design example, is there any changes made in the design? If yes, which part?
2. Is the design already programmed? It seems like it has but error at readback. If so, is the design functioning as intended?

Hi,

Greetings!

1. When following the design example, is there any changes made in the design? If yes, which part?
   - No change on design example. We are used same master_image 
2. Is the design already programmed? It seems like it has but error at readback. If so, is the design functioning as intended?

          - Write flash is completed. Readback error
          - when we perform step 4(Do you want to reconfig FPGA?) with proper start address. its showing " Users Watchdog Timer timeout"
          - The design not functioning as intended

        Step4 : Do you want to reconfig FPGA?
        (Please input 'y' or 'n' to select, and press ENTER to go on):y

Hi,

Can you try to test the design with the jic file first.

1. Program the Flash with the jic file shipped with the design.
2. Shut down the system and then power on again, observed four red LED lit on.
3. Install the driver and run the application, select not to download the application image.
4. Select reconfig the FPGA, use start address 0x2000000 or 0x4000000

If this is working, then the hardware is good for further testing.

Hi

Yes,
As I mentioned in my first post I am able to swap the application through PCIe using driver and application which we downloaded through JTAG.
We are able to swap the application and factory image frequently without any issues.

We don't have issue with setup or hardware. Same setup used for PCIe based user projects

@NurAiman_M_Intel 

Any suggestions on this for me?

[NurAiman_M_Intel]

Hi,

When checking with our internal team, we notice that your rpd file name does not match with the one shipped with our design example. Did you use the one shipped with our design?

Hi @NurAiman_M_Intel 

Thanks for your response.

We have downloaded the project from below link(Design store )

https://fpgacloud.intel.com/devstore/platform/20.4.0/Pro/intel-arria-10-fpga-remote-system-update-via-pci-express/

arria10_pcie_rsu.par.

We extracted the project and using it.
when we do that we got master image and its named like below image

 

We used same rpd file. Initially we tried with our own rpd file.  Errors are same. 

Below one is with master image (PFA for detailed log)

Hi,

I am checking this with my team. I will get back to you soon.

[NurAiman_M_Intel]

Hi,

From your reply, this imply that the PCIe link is good, the master jic file is good, the path to trigger reconfig is working and the reconfig process completed without issue.

Did you refer to the ru.map file for the start address and end address when running the application? If no, please do.

Regards,

Aiman

[MIT_R_D]

@NurAiman_M_Intel 

Yes, We are using Start Address and END Address as per ru.map file. 

Page_0 0x00000020 0x01569FFF (0x0156958B)
Page_1 0x02000000 0x03568FFF (0x03568F27)
Page_2 0x04000000 0x05568FFF (0x05568F27)

[NurAiman_M_Intel]

Hi,

1. I noticed from all your previuos reply, all the details were tested using Page_4 address.

Have you try to program Page_0 and Page 1? Are they success?

Page_0 0x00000020 0x01569FFF (0x0156958B)

Page_1 0x02000000 0x03568FFF (0x03568F27)

Page_2 0x04000000 0x05568FFF (0x05568F27)

2.On top of that, at step 4, did you press Y? If yes, did the FPGA able to boot up and work as intended?

Step4 : Do you want to reconfig FPGA?

@NurAiman_M_Intel 

1. Have you try to program Page_0 and Page 1? Are they success?
    Yes, We try to program Page_0 and Page 1; its not success

2.On top of that, at step 4, did you press Y? If yes, did the FPGA able to boot up and work as intended?
   No, When we program Page_0 or Page_1 or Page_2 through PCIe, FPGA did not boot up

[NurAiman_M_Intel]

Hi,

Can you please try again by following below:

[1] Erase the flash using Quartus Programmer.

[2] Restart the flow by generating the JIC file with image 0, image 1 and image 2 in it and then program it into the flash.

(Follow page 8 in the document)

[3] generate the rpd file for image 2, then try again to update the image using terminal

(follow page 18 - section 3.7.2)

Aiman
