Uboot & ATF

The minimum required version is 2024-11-08, while the latest version is 2025-03-04 for the latest U-Boot feature support. The OpenWrt/24.10 or trunk image type is ITB, which cannot be loaded if the original U-Boot is too old. Please update to a newer U-Boot that supports both OpenWrt 21.0x and OpenWrt 24.xx image types.

• Since U-Boot is still released as a tarball, please log in to the DCC or contact the corresponding window to obtain the latest U-Boot and ATF source code.

Also need DTS overlay to enable 10G ethernet for one-time uboot console setting. "0. U-Boot console"

• GMAC1 is AQR113C 10G PHY case

setenv bootconf_extra mt7988a-rfb-eth1-aqr#mt7988a-rfb-eth2-aqr 
saveenv

• GMAC1 is Mediatek Internal 2.5G PHY case

setenv bootconf mt7988a-rfb-spim-nand-nmbm
setenv bootconf_extra mt7988a-rfb-eth1-i2p5g-phy#mt7988a-rfb-eth2-aqr

SPIM-NAND

Note: Please follow the SOP below to upgrade the bl2 and fip on your board.

1. Upgrade the bl2.img file according to the DRAM type, and program this file using the "3. Upgrade ATF BL2" option in the U-Boot menu.

2. Upgrade the flp.bin file, and program this file using the "4. Upgrade ATF FIP" option in the U-Boot menu.

3. Reboot the board. You can now upgrade the ITB image using "2. Upgrade firmware"

EMMC

Note: Please follow the SOP below to upgrade the U-Boot image and GPT partition on your board.

1. Upgrade u-boot_1g.bin, and program this file using the "6. Upgrade bootloader only" option in the U-Boot menu.

2. Program GPT_EMMC_mt798x_itb using the "7. Upgrade partition table" option in the U-Boot menu.

3. Reboot the board. You can now upgrade the ITB image using "2. Upgrade firmware"
