7 This repository tracks bugs for the Raspberry Pi 4 bootloader EEPROM and Linux update scripts.
9 * If you suspect a hardware problem then please read the [Boot Problems](https://www.raspberrypi.org/forums/viewtopic.php?p=437084) post first before contacting the reseller.
10 * Support questions or should be posted on the Raspberry Pi [General Discussion](https://www.raspberrypi.org/forums/viewforum.php?f=63)**
12 **Mandatory information**
14 * Board revision (cat /proc/cpuinfo | grep Revision)
15 * Operating system version .
16 * Details of any hardware attached e.g. links to USB
17 * Photo of the HDMI diagnostics screen, UART trace.
20 A clear and concise description of what the bug is.
23 Steps to reproduce the behavior:
25 **Expected behaviour**
26 A clear and concise description of what you expected to happen.
28 **Bootloader version and configuration**
29 Please include the bootloader version and config.
31 vcgencmd bootloader_version
32 vcgencmd bootloader_config
35 **SD card boot (please complete the following information):**
37 - Partition information (sudo fdisk -l) if you are able to obtain this from another computer.
39 **USB boot (please complete the following information):**
40 Verify that the the USB device works correctly when hot-plugged under Linux and attache the output of 'lsusb -vvv'
42 **Network boot (please complete the following information):**
43 Network boot bug normally require one or more of the following log types. [PiServer](https://github.com/raspberrypi/piserver) is the officially supported network boot server.
45 - DHCP server configuration files e.g. dnsmasq.conf
46 - Wireshark binary packet capture
47 - UART logs with `uart_2ndstage=1` set in `config.txt`
49 **NVMe boot (please complete the following information):**
52 sudo apt-get install nvme-cli
54 sudo nvme id-ctrl -H /dev/nvme0
55 sudo nvme list-ns /dev/nvme0
56 sudo nvme id-ns -H /dev/nvme0 --namespace-id=1
59 **Additional context**
60 Add any other context about the problem here.
62 The [Bootloader configuration](https://www.raspberrypi.org/documentation/computers/raspberry-pi.html#raspberry-pi-4-bootloader-configuration) page describes how to enable UART or NETCONSOLE logs. For complex USB boot issues NETCONSOLE logs are recommended.
