Discrete GPU Access Issue

We are currently having an issue accessing the discrete GPU on Drive PX2 Autochauffeur. We can see the stats in tegrastats and query the current frequency.

However, running examples such as nvrm_gpuclk will return an error with a bug report: Bug 200215060 workaround enabled.
Using cudaGetDeviceProperties and cudaGetDeviceCount is also fruitless and only the integrated GPU is reported as available.

Incidentally, we tried updating our PX2 (so maybe that solves the problem) using the SDK manager, but the second step does not load with a loadStage2Error.

Thank you for your help in advance.

Dear soroushbv43y,
Do you see any issue in updating to Drive 1.0 using SDKManager? Could you provide details about the error. Can you check the following thread https://devtalk.nvidia.com/default/topic/1046975/drive-agx/sdkmanager-0-9-9-flash-agx-failed/post/5313645/#5313645 to see if the provided solution worked for you and update us

Thank you for your response. SDKManager fails before step 3. I have attached the error we get in Step 2. This is even before we can enable logging, so we do not know the source of this error.

Here is the screenshot of the error: https://www.dropbox.com/s/t5uhnrqyf3r0m6d/Step2.png?dl=0

Dear soroushbv43y,
This is strange. Please double check System requirements, Proxy settings section in sdkmanager user guide (https://developer.nvidia.com/DRIVE/secure/files/SDKManagerUserGuide.pdf)

Can you delete ~/.nvsdkm folder and download sdkmanager again (https://developer.nvidia.com/DRIVE/secure/files/sdkmanager-0.9.9.2351) and check installing.

Dear soroushbv43y,
Any update here?

Thank you so much for your response.
I have tried the second solution to no avail.

As for system requirements, we were using Linux Mint 19.1 based on Ubuntu 18.04 LTS. I have tried SDKManager on virtual machines (without the USB connection) with the same result. I have tried everything short of installing Ubuntu 16.04 on a physical machine. I will try that and get back to you. Again to reiterate, the issue is in Step 02 while loading the license agreement, etc.

Going back to the original question, do you think that updating to the latest Drive OS would solve our issue with dGPU?

Dear soroushbv43y,
If the issue is related SW, it can be resolved by re-flashing the board. If the issue with HW, you will still notice this issue, in that case get back to us again.

Thank you so much for your help so far. We dedicated a computer just for updating Drive PX2 with Ubuntu 16.04 and we were able to pass step 2 with no problem. However, in step 3, the process is stuck again with the following errors:

The installer indicates that the download is completed successfully but the details tab reflects these errors. The installation freezes at 15% (I have tried leaving it for a full day). I would appreciate your help regarding this issue.

I have managed to bypass the previous problem. However, I now consistently get the following errors when I try to flash Tegra A, or Tegra A+B, or Tegra B. I would appreciate your help on this matter.
