# Raspberry Pi4 bootloader EEPROM release notes ## 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.
