* 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.
* 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.
* 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
* 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
* New beta recovery.bin which can update the VLI EEPROM before
start.elf is loaded. This is the recommended and default method
because no USB devices will be in use at this stage.
* Extend the USE_FLASHROM configuration to use the vl805 tool
to program the VL805 directly.
* Generate SHA256 checksums in .sig files for the bootloader and
and VL805 images. This is required by the new recovery.bin to
guard against corrupted files being flashed to the EEPROM(s).
* Various variable renames to distinguish between the bootloader
and the VL805 images.
Select the recovery.bin to use according to FIRMWARE_RELEASE_STATUS
in order to allow a beta test version of recovery.bin to be provided
without risking breaking the stable version of recovery.bin
