* Signed boot and HTTP boot mode HTTP boot mode is supposed to be disabled if signed boot is enabled and a host is not specified. The code is checking the http_secure flag to enforce this. But this is valid now we support custom CA certs. Only disable HTTP mode if we're using the default HOST. * Implement TCP window for net boot The minimal IP stack used for https booting lacks the ability to cache packets received out of order, which can lead to severe slowdown when it happens. The problem seems to affect some ISPs more than others. The receive window implemented here copes with packet losses of 10%. * netboot: Correct the TCP MSS * Correct msecs in debug timestamps The fractional part of timestamps in UART debug output was showing the 100ths and 1000ths of a second, rather than 10ths and 100ths, causing strange sequences that appear to jump backwards.

This repository contains the scripts and pre-compiled binaries used to create the rpi-eeprom package which is used to update the Raspberry Pi 4 and Raspberry Pi 5 bootloaders EEPROM images.
Support
Please check the Raspberry Pi general discussion forum if you have a support question.
Reset to factory defaults
To reset the bootloader back to factory defaults use Raspberry Pi Imager to write an EEPROM update image to a spare SD card. Select Misc utility images under the Operating System tab.
