I have a hailo 8L M.2 B+M type accelerator, and I connect it to the M.2 connector of my axu5evb-e card. However, when I type the lspci command, my hailo device does not appear.
I have the same issue, i have connected it on a PCIE x 4 converter, and used the lspci command. As a result, these’s nothing show but this:
00:00.0 PCI bridge: Xilinx Corporation Device d021
Hey @yutao_xiang,
Welcome to the Hailo Community!
Make sure the module is actually seated properly in the M.2 slot (sometimes it’s not clicked in all the way), verify that the slot itself is enabled in your BIOS, and try rebooting after installation if you haven’t already.
Now, since you’re using a PCIe x4 converter, there’s something important you need to know: the bare Hailo-8L chip has specific power requirements that a basic adapter probably won’t provide. It needs 1.2V for the core, 3.3V for I/O, and a precise 100MHz reference clock. The official AI-kit board has all this built in, but most simple adapters don’t.
If you want to go the adapter route, you’ll need one that includes the necessary voltage regulators and clock generator - you can reference the AI-kit schematic to see exactly what’s needed. Otherwise, you’d have to supply these externally.
So here’s what I’d suggest checking in order:
- Physical connection - reseat the module and make sure it’s firmly in place
- BIOS settings - confirm the PCIe/M.2 slot is actually enabled
- Reboot - if you haven’t already
- Adapter specs - this is probably the culprit - verify your converter has the power regulation and clock generation the Hailo-8L needs
Hope this helps!
