Error occurred during enumeration of RISC-V harts (no harts found)

[CShih23]

My OS is Ubuntu 22.04 with kernel version 6.5.0-28-generic, and I'm using the Arria® 10 GX FPGA Development Kit (10AX115S2F45I1SG). My Quartus Prime version is 23.4.
Following the 'AN 985: Nios® V Processor Tutorial', I went through the flow of Quartus Prime and RiscFree. The simulation was successful. However, after programming the .sof file into the device and attempting to use RiscFree for debugging, I encountered an error stating 'error occurred during enumeration of RISC-V harts.' Additionally, when I tried 

niosv-download -g ./hello.elf -c 1

it also displayed an error.

juart-terminal also stucked and showed nothing.

This is the platform designer:


As a first-time user, I hope this issue can be resolved. Additionally, I've been experimenting with oneAPI. However, when I attempted to do 'aocl install intel_a10gx_pac,' it returned an error stating 'Error: unsupported OS.' Could this mean that my OS version is not supported, or should I try using a different BSP? (oneAPI 2024.1)

Thanks.

Hi

Did you met any error when downloading the sof file?

Another thing could you try the niosV-download command without any parameter as below:

"niosv-download sw/app_hal/build/hello.elf"

It seems like I forgot to assign the clock PIN on Arria 10 GX. Besides, when I utilized Nios V/M on Arria 10 downloaded from the design store, simply changing the part and assignment did not work. Therefore, I configured the Platform Designer from scratch. Anyway, it now works.

Thank you for your response.
