Unable to usb boot raspberry pi zero v1.3

[adrian-amaglio]

I got an error when I try to boot a pi zero from usb. I am following this tutorial: https://dev.webonomic.nl/how-to-run-or-boot-raspbian-on-a-raspberry-pi-zero-without-an-sd-card/comment-page-1

Since I do not understand what it is happening, I don’t know which information you need to understand the issue.

I start usbboot, then I plug the pi zero. All following logs are printed, then nothing happens anymore. Execution trace

$  sudo ./rpiboot -v -d boot/

In the same time, dmesg logged :

[ 2103.768199] usb 1-2: new full-speed USB device number 18 using xhci_hcd

I thought it was a lack of power in the pi, so I plugged it simultaneously to the computer and to a power supply. The result was the same.

I tried with two raspberry pi zero V1.3 and two different usb wire with no changes.

I did those tests from two computers with same results:

manjaro 20.20
linux 5.8.18-1-MANJARO

linuxmint 4
LMDE 4
linux 4.19.0-12-amd64

I connected a monitor to the pi, it got no signal, so no boot seems to happend. The "act" led is not blinking.

I made sure OTP usb boot bit was set adding program_usb_boot_mode=1 to /boot/config.txt in a raspbian. Then I booted the pi from that SD card.

Is this issue related to udev ? Is it related to my raspbian image or to the initrd I generated ?

I don't know how old the bootcode.bin is you're using but it might be worth trying the one from https://github.com/raspberrypi/usbboot/pull/64#issuecomment-707540855

Thanks a lot, it works ! I don’t remember copying the bootcode.bin file. It might be the one of the msd directory.
