# Raspberry Pi4 bootloader EEPROM release notes
|
|
|
|
## 2020-04-12 Update beta+stable recovery.bin
|
|
* If the VL805 image was updated but the bootloader was not then
|
|
recovery.bin would incorrectly switch to infinite flashing activity
|
|
LED pattern used in the rescue image to prevent infinite reboots.
|
|
Fix recovery.bin to reboot in this case. The current 'critical'
|
|
release does not have this problem.
|
|
* Fix uart_2ndstage logging in beta/stable recovery image.
|
|
* Change recovery.bin to reboot instead of displaying an error patern
|
|
if there are no EEPROM images. The Raspberry Pi Image makes it very
|
|
difficult to create a broken rescue image but a stray recovery.bin
|
|
could stop Raspbian from booting.
|
|
* Fix detection of VL805 EEPROM in recovery.bin
|
|
|
|
N.B. These recovery.bin file used for critical updates and the rescue
|
|
image does not suffer from these bugs.
|
|
|
|
## 2020-04-09 Add 2020-04-09 beta firmware.
|
|
* Experimental tweaks for PLL analog setup to reduced jitter and
|
|
improve PCIe reliability on slower silicon.
|
|
|
|
## 2020-04-07 Promote 2020-03-19 beta firmware to stable.
|
|
* No major bugs reported. Promote this to stable as a step
|
|
towards getting HDMI diagnostics into the default firmware
|
|
via a critical update.
|
|
|
|
## 2020-03-19 Add 2020-03-19 beta firmware
|
|
* Minor mods for manufacture test.
|
|
|
|
## 2020-03-16 Add 2020-03-16 beta firmware
|
|
* Fix DHCP Option97 GUID generation. The MAC LSB portion was previously
|
|
always zero.
|
|
|
|
## 2020-03-11 Add 2020-03-04 beta firmware recovery
|
|
* Support static IP address configuration. The following fields may be
|
|
set manually using dotted decimal address. If set, then DHCP if skipped.
|
|
* CLIENT_IP
|
|
* SUBNET
|
|
* GATEWAY
|
|
* TFTP_IP
|
|
* If a fatal bootloader error occurs then an HDMI diagnostics screen is
|
|
displayed at VGA/DVI resolution on both outputs for two minutes.
|
|
This may be disabled by setting DISABLE_HDMI=1 in the EEPROM
|
|
configuration OR setting display_splash=1 in config.txt.
|
|
* Allow the PXE menu option to match a custom string specified by
|
|
PXE_OPTION43. The default is still "Raspberry Pi Boot"
|
|
* DHCP_OPTION97 - The default GUID has now changed to
|
|
RPI4+BOARD_ID+ETH_MAC_LSB+SERIAL in order to make it easier to
|
|
automatically identify Raspberry Pi computers. The old behaviour
|
|
is enabled by setting DHCP_OPTION97=0 which simply repeats the serial
|
|
number 4 times.
|
|
* SELF_UPDATE. If SELF_UPDATE is set to 1 in the EEPROM configuration AND
|
|
config.txt contains bootloader_update=1 then the bootloader will looking
|
|
for pieeprom.upd and vl805.bin and apply these firmware files if
|
|
they are different to the current image, before doing a watchdog reset.
|
|
This should make it easier to update the bootloader for network
|
|
booted setups because an SD card is not required for recovery.bin.
|
|
As usual, TFTP should only be used on private networks because the
|
|
protocol is not secure against spoofing.
|
|
* recovery.bin. The beta recovery.bin will now display a green screen
|
|
via HDMI if successful or red if a failure occurs.
|
|
|
|
## 2020-02-27 rpi-eeprom-update & firmware
|
|
* Remove the dependency check for the vl805 utility. This is deprecated
|
|
and there is no 64-bit version. The file is still available in Github
|
|
for anyone who wants to continue using USE_FLASHROM or create their
|
|
own scripts.
|
|
* Add a stable firmware directory based on the latest beta release.
|
|
Stable should be interpreted as feature-freeze releases. In this
|
|
case the core network boot is stable enough for most scenarios
|
|
and this de-risks adding new more experimental features in the
|
|
beta folder.
|
|
|
|
## 2020-01-22 - vl805 00137ad
|
|
* Set the default/critical vl805 version to be 00137ad. This has the
|
|
same power savings as 0137ab but with fixes for USB webcams.
|
|
|
|
## 2020-01-17 - Git 5e86aac5f (BETA) RC4
|
|
* Handle DHCP option 0 - padding
|
|
* Fix SD card voltage detection
|
|
|
|
## 2020-01-14 - rpi-eeprom-config
|
|
* Fix padding calculation
|
|
|
|
## 2020-01-09 - Git df0ff18c (BETA) RC3
|
|
* Fix parsing of multiple menu entries in PXE options.
|
|
* Fix regression in IP address parsing
|
|
|
|
## 2019-12-03 - Git f0d7269d4 (BETA) RC2
|
|
* Fix handling of multiple menu options with TFTP Option43
|
|
* Ignore unsupported modes in BOOT_ORDER instead of stopping.
|
|
|
|
## 2019-11-18 - Git b6a7593d6 (BETA) RC1
|
|
First release candidate before this beta is moved to a stable release series.
|
|
|
|
* Avoid resetting TFTP prefix after retries or if start4.elf is not found.
|
|
* Add MAC_ADDRESS option which allows the OTP Ethernet MAC address to be
|
|
overriden. An VideoCore firmware update will propagate this forced
|
|
mac address to device-tree/cmdline in the near future.
|
|
* Various internal refactorings to prepare for USB MSD storage boot in
|
|
the next beta-series.
|
|
* Enable high-speed mode for EMMC cards.
|
|
|
|
## 2019-10-17 - rpi-eeprom-update + recovery.bin
|
|
* 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.
|
|
|
|
## 2019-10-16 - Git 18472066 (BETA)
|
|
* Ignore trailing characters when parsing in PXE boot menu option.
|
|
* Improve error handling with unformatted sd-cards.
|
|
## 2019-10-08 - Git 26dd3686c (BETA)
|
|
* TFTP now uses RFC2348 blksize option to get 1024 byte blocks if the server supports it.
|
|
* Fix DHCP handling of SI_ADDR
|
|
* TFTP_PREFIX and TFTP_PREFIX_STR options for mac-address or string literal prefix.
|
|
* Improved support for standard capacity and SDv1 cards.
|
|
|
|
## 2019-09-25 - Git 4d9824321 (BETA)
|
|
* Increase TFTP timeout to 30s as default & bootconf.txt
|
|
* Fix intermittent boot freeze/slowdown issue after loading start.elf
|
|
* Don't load start.elf during network boot if start4.elf exists but the download times out.
|
|
## 2019-09-23 - Git c67e8bb3 (BETA)
|
|
* Add support for network boot
|
|
* Configurable ordering for boot modes (BOOT_ORDER and SD/NET_BOOT retries)
|
|
|
|
## 2019-09-10 - Git f626c772
|
|
* Configure ethernet RGMII pins at power on. This is a minor change which
|
|
which may improve reliability of ethernet for some users.
|
|
|
|
## 2019-09-05 - Git d8189ed4 - (BETA)
|
|
* Update SDRAM setup to reduce power consumption.
|
|
|
|
## 2019-07-15 - Git 514670a2
|
|
* Turn green LED activity off on halt.
|
|
* Pad embedded config file with spaces for easier editing by end users.
|
|
* Halt now behaves the same as earlier Pi models to improve power behavior at halt for HATs.
|
|
* WAKE_ON_GPIO now defaults to 1 in the EEPROM config file.
|
|
* POWER_OFF_ON_HALT setting added defaulting to zero. Set this to 1 to restore the behavior where 'sudo halt' powers off all PMIC output.
|
|
* If WAKE_ON_GPIO=1 then POWER_OFF_ON_HALT is ignored.
|
|
* Load start4db.elf / fixup4db.dat in preference to start_db.elf / fixup_db.dat on Pi4.
|
|
* Embed BUILD_TIMESTAMP in the EEPROM image to assist version checking.
|
|
|
|
## 2019-05-10 - Git d2402c53 (RC2.1)
|
|
* First production version.
