+This repository tracks bugs for the Raspberry Pi 4 bootloader EEPROM and Linux update scripts.
+
+Support questions should be posted on the Raspberry Pi [General Discussion](https://www.raspberrypi.org/forums/viewforum.php?f=63).

+If your Raspberry Pi does not boot at all then please consult the [Boot Problems](https://www.raspberrypi.org/forums/viewtopic.php?p=437084) forum post.

-N.B The bootloader does not persist in memory and if the rainbow splash screen has been displayed the issue is likely to be in the firmware or Linux. If so, it's better to target the bug in the [Firmware](https://github.com/raspberrypi/firmware/) or [Linux](https://github.com/raspberrypi/linux/) repositories first e.g. NFS, USB or dmesg logs would be Linux issues.

 **Bootloader version and configuration**
-If you have modified the default bootloader release or configuration then please attach the bootloader configuration (vcgencmd bootloader_config) and version (vcgencmd bootloader_version)

 **SD card boot (please complete the following information):**
- - OS e.g. Raspbian
  - SD card type
- - Partition information (fdisk -l) if you are able to obtain this from another computer.

 **Network boot (please complete the following information):**
-Network boot configuration can get very complicated. To get started we recommend using [PiServer](https://github.com/raspberrypi/piserver) and this is the official test/reference configuration. For other configurations, packet capture or a UART log is nearly always required because setting up custom network configurations to investigate bugs is extremely time-consuming and error-prone.
+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.
 
  - DHCP server configuration files e.g. dnsmasq.conf
  - Wireshark binary packet capture
  - UART logs
 
 **USB boot (please complete the following information):**
-For issues booting with specific USB devices please verify that the system boots from an SD-card with the same devices connected and attach the results of 'lsusb -vvv'. This helps to rule out USB HUB power issues.
-In the beta release it's likely that a UART or NetConsole boot trace will be required.
+Verify that the the USB device works correctly when hot-plugged under Linux and attache the output of 'lsusb -vvv'

+The [Bootloader configuration](https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2711_bootloader_config.md) page describes how to enable UART or NETCONSOLE logs. For complex USB boot issues NETCONSOLE logs are recommended.
