Trying to use the USBBOOT option

[Wessel van Norel]

Hi,

I recently got myself a clusterHAT and since I was lacking SD cards I tried the USBBOOT solution[1]. Unfortunately it doesn't seem to work for me, but I"m not sure what I'm doing wrong.

I've a rpi 4B as my cluster hat controller. On it I installed the 64 bit CNAT - Lite Controller image. And I've placed 4 rpi zero 2 w boards as my cluster nodes. I've downloaded the bookworm 2024-07-04 arm64-lite-usbboot image and unpacked it 4 times, to /var/lib/clusterctrl/nfs/p[1-4]/

When I try to boot it up I see the USB device being detected and rpiboot starts to initialize. First thing that strikes me as odd is the double slash in the path to the bootcode.bin, but that doesn't sound like a real issue. And the detection of the serial number always returns 0. And then it fails to transfer data since the length goes negative. And from there it loops.

Can someone tell me how to proceed to debug this. I've tried running rpiboot standalone and add an extra v to the command to see if it provided more details on what goes wrong, but that didn't help me.

The standard output for me is at the bottom of this message.

Thanks in advance.

Kind regards,

Wessel

Never mind, problem seems to exist between keyboard and chair... Got the SD cards today and that worked, removed those SD cards again and now USBBOOT also works... But I noticed the boards where not positioned correctly, so I guess they were connected, but not properly.

Everything is fine now.

Thanks for creating this product.

Kind regards,
