Troubleshooting Orca Accelerator Installation on Raspberry Pi 5: Device Not Found Issue

Product Support
1

We’re currently facing some challenges configuring the Orca accelerator on a Raspberry Pi 5. We’ve followed the instructions provided on the website under the “Linux Kernel Driver Installation” section, but we’ve encountered an issue.

We completed the initial steps (1-6) successfully, but step 7 (“If secure boot is enabled, it will prompt to add the certificate used to sign the driver to MOK”) did not occur.

Following the troubleshooting steps:

The PCIe device seems to be recognized (output: “0000:01:00.0 Processing accelerators: Device 1f0d:0100 (rev 01)”)
The Orca Kernel Driver appears to be installed (output: “cdapci 49152 0”)
The user permissions seem to be set up correctly.

However, when we tried to run the ORCA utilities after installation, we received this error:
“dgoinfo: error [ERROR]Device not found
No device found
dg_orca_dev.h: 61 [LCL::OrcaDevices::OrcaDevices]”

We would greatly appreciate any guidance on resolving this issue. Could you provide any additional troubleshooting steps or insights?

Pls provide the output of the following. Sample run is provided as an example

execute lspci
example:
degirum@dgsrv058:~ $ lspci
0000:00:00.0 PCI bridge: Broadcom Inc. and subsidiaries BCM2712 PCIe Bridge (rev 21)
0000:01:00.0 Processing accelerators: Device 1f0d:0100 (rev 01)

0001:01:00.0 Ethernet controller: Raspberry Pi Ltd RP1 PCIe 2.0 South Bridge

execute sudo lspci -vvvxxx -s 0000:01:00.0
where 0000:01:00.0 is got from the previous step (adjust this accordingly)
example:
degirum@dgsrv058:~ $ sudo lspci -vvvxxx -s 0000:01:00.0
