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.
* Avoid default PCIe / XHCI probe on CM4 unless required for the
current boot mode (USB_MSD or NVME).
* Leave PCIe RC in reset state when loading start.elf except for
USB-MSD mode.
* Minor update to BRCM SDRAM settings.
* Add USB_MSD_STARTUP_DELAY option (default 0 option).
This adds a configurable delay (in milliseconds) the first time
the USB host controller is initialised before device enumeration.
Normally, this should not be required. However, some HDD enclosures may
require an extended startup delay in order to spinup drives. Without this
the get-capacity command may stall and timeout.
* Use the latest BRCM SDRAM settings.
* FAT12 support for small bootloader ramdisk images.
* Minor file-system performance optimisations.
* Added recovery.bin config.txt option (erase_eeprom=1) to perform
an SPI chip-erase operation instead of programming the bootloader image.
Move these out of the directories selected by APT now that 2020-09-03
is the default release.
Preserve the releases which were promoted to stable in-case these are
referenced via scripts.
* Reset Ethernet MAC + PHY if final boot mode is not network boot
See: Kernel warning and network failure when attempting to use
the network after bootloader times out. #144
* Improve handling of multiple bootable USB devices and remove USB_MSD_BOOT_MAX_RETRIES
* Resolve: No DHCPACK with DHCP relay agent #58
* Toggle USB root hub port power for 200ms on the first USB MSD boot attempt
See: Bootloader can't boot via USB-HDD after system reboot #151
* Update bootloader handover to support uart_2ndstage - requires a newer
start.elf firmware which will be via rpi-update.
* Assert PCIe fundamental reset if the final bootmode was not USB-MSD
because the OS might not do this before starting XHCI.
* Resolve: Unable to boot from USB MSD - Seagate 5Tb HDD backup drive #139
* Increase USB MSD timeout from 10 to 20 seconds.
* Max retries now default to zero because the default BOOT_ORDER includes
restart (0xf). Therefore, each boot-mode is now tried once before moving
to the next mode. The retries mechanism is largely redudant now that
the loop/restart mode exists.
* If TFTP fails and network boot retries > 0 then wait 5 seconds before
retrying to avoid overloading a misconfigured TFTP server.
* Map undefined boot-modes in BOOT_ORDER to SD (0x1) instead of stopping.
* Add missing pieeprom-2020-05-28
* Resolve: USB boot fails if the GPT contains no basic data or EFI partitions #130
* Resolve: Fix default BOOT_ORDER in mass storage beta #129
* Resolve: Add support for booting from a "superfloppy" disk #120
* Resolve: USB MSD timeout message - incorrect units #131
* Resolve: Recognize efi partition (0xef) as a valid boot #126
* The HDMI diagnostics screen now displays the most significant bytes of the SHA-256 of the config.txt file.
Now that 2020-04-16 has been released and appears to be stable move
the older binaries to and old (deprecated) directory. There's no
need to include old beta binaries in OS packages.
* Fix uart_2ndstage in the recovery.bin
* Fix missing watchdog reset if only the VL805 image is updated.
* Fix detection of VL805 EEPROM in recovery mode.
* If no EEPROM images are present then recovery.bin now renames
itself and reboots instead of treating this as an error.
Tweak analog settings for possible improvements to PCIe reliability
but unlikely to make a difference for most users and requires
corresponding changes in start.elf (future rpi-update)
* Option to restrict automatic updates to bootloader and/or vl805
* Change the machine mode output variables
* recovery.bin: Rebuild from Gitlab
* Rename CURRENT_TS and LATEST_TS in machine output
