Require python3 instead of relying on all distros including
python-is-python3 etc.
The code will still work with python2 but distros which require
python2 will need to maintain that as a downstream patch.
* 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.
At present, the update script exits cleanly in the case it finds itself
run on Pi hardware prior to the 4/CM4/400, but if installed on non-Pi
hardware exits with various slightly cryptic errors (missing vcgencmd
and some subsequent math errors from trying to bit-shift the empty
BOARD_INFO variable).
This patch adds a similar exit to the non-Pi 4 case, with a slightly
more useful message.
* 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.
Display a warning if the bootloader version is downgraded. This can
happen when swapping boot-media and the bootloader configuration is
changed from an OS with an old version of the rpi-eeprom package.
Remove the duplicated "update pending" and "to cancel update" messages.
