* [tryboot] conditional statement + tryboot_a_b mode
* Support custom OTP mac addresses
* Increase TFTP_MAX_BLOCK_SIZE
* Stop NVMe cleanly
* Fixes for NETCONSOLE parsing and initialisation.
* Long filename support for start_file / fixup_file.
* Secure boot and display debug info on the diagnostis screen.
Add a new EEPROM property that allows the Ethernet MAC address
programmed during manufacture to be overridden a value in the
Customer OTP register.
MAC_ADDRESS_OTP=A,B
where A and B are the customer row numbers (0..7)
Enable long-filenames & sub-directories for start_file & fixup_file.
Use Unix path separators with a maximum path of 255 characters.
Relative paths (. or ..) are not supported.
Enable Network Install in the default bootloader release.
This release is signed with the secure-boot key and supports
the new HTTP boot-order for downloading signed boot images for
automated provisioning systems.
* Fix netboot reboot failure on Pi 4B R1.1 if OS enables IDDQ power saving
https://github.com/raspberrypi/rpi-eeprom/issues/417
* Fix incorrect error code (configuration error) on EEPROM update failure.
* Enable more verbose errors for EEPROM update failures
* Includes new net install feature, enabled by default for Pi 4 and Pi 400
* New net install download screen may appear on boot if a boot location can't
be found or if boot is slow. Alternative press and hold shift on boot to
start net install.
* New HTTP boot order.
* Bootloader diagnosis screen is now 720p if supported by your monitor.
* Self update mode is now enabled during SD/EMMC boot.
* The PARTITION number can now be specified as an EEPROM property.
* Allow smaller MSD discovery timeouts to be specified.
* Some tweaks and fixes to IPV6 netboot.
* Increase the max ramdisk size to 128MB
* Increase timeout of early SD/EMMC commands to 100ms
Net install changes.
* Net install is initiated on boot if shift is pressed.
* New HTTP boot order (7) and configuration parameters,
HTTP_HOST, HTTP_PATH, HTTP_PORT to set url
Other interesting changes.
* Increase the max ramdisk size to 128MB
* Increase timeout of early SD/EMMC commands to 100ms
Net install changes.
* Got rid of confirmation step that required you to press <Space> to
initiate net install. Now just long press <Shift>
* Updated the screen text to make it more obvious the device is still
trying boot when the net install is showing.
* Fixed a DHCP net install bug which caused us to lose the
gateway address.
* Fixed a bug with the uIP timers which could cause net install to
always fail.
* Implemented resume and retry on download failure.
Other interesting changes.
* Allow smaller MSD discovery timeouts to be specified.
* Some tweaks and fixes to IPV6 netboot.
Interesting changes since the last default release
* Support and bug fixes for all Compute Module variants.
* NVMe interoperability fixes
* FAT/GPT fixes and file-system performance improvements.
* Add secure-boot support for industrial applications
See https://github.com/raspberrypi/usbboot/blob/master/secure-boot-recovery/README.md
* Added ramdisk / boot.img - for RPIBOOT and secure-boot.
* Promote the recovery.bin from stable to default. This avoids an
issue where recovery.bin fails to load on large FAT32 boot partions with
32K clusters.
* Improve the error logging if a file is too large and truncated.
* Increase the maximum size of the ramdisk to 96MB.
* Preliminary changes to expose the boot-mode used to load the
ramdisk via device-tree.
N.B. Secure boot is only recommended for industrial customers and is
currently a beta release. This can only be enabled via RPIBOOT
https://github.com/raspberrypi/usbboot/blob/master/Readme.md
* Update the FAT detection to support FAT16 for EFI/ESD paritions with
GPT instead of assuming FAT32. The latest firmware is also required
for a similar update.
* Increase the timeouts for MSD SCSI commands to reduce the risk of
timeouts when probing the capacity of slow to start devices
e.g. USB RAID with spinning disks.
This release makes major changes to the bootloader file-system code in
order to support new features and should be treated as a bleeding edge BETA
release!
* Improve file-system performance to reduce boot time.
* Preliminary support for IPV6 TFTP. Requires an updated start4.elf.
Details to follow.
* Fix VL805=1 option for CM4 IO boards that follow the same XHCI
design as Pi4B. Start.elf will be updated in the next rpi-update
release and the latest CM4 DTBs are required for the 'XHCI reset controller'
* Preliminary suppport for loading signed boot image files.
Requires updated GPU firmware.
