Got the following error:

hailo_platform.pyhailort.pyhailort.HailoRTPCIeDriverException: PCIe driver failure. run ‘dmesg | grep hailo’ for more information

This is the the dmesg content:

Any idea what can be the issue? I’m using Hailo 8L

Hey @Erez,

Based on your dmesg output showing PCIe driver issues with the Hailo-8 on Raspberry Pi, here’s a quick breakdown and steps to try:

Understanding the Issues:

  • The driver and firmware initialize correctly.
  • You’re seeing timeout errors during shutdown.
  • The device disconnects unexpectedly.

Steps to Troubleshoot:

  1. Test with Different PCIe Cable or Power Supply: If you have another PCIe cable, slot, or power supply, try these with the Hailo-8 to rule out hardware stability issues.

  2. Run hailortcli scan: This will help confirm if the driver is correctly installed and the device is detected.

  3. Reinstall the Driver: If the above steps don’t help, try reinstalling the driver to see if the issue persists.

Let me know if these steps make any difference!

Looking at the pci driver code seems like it’s a failure to set a mailbox

Can you elaborate what does “Mailbox” mean?
