- Switched to the binman-atf-mainline scenario with the same rkbin DDR blob
rk3399_ddr_933MHz_v1.25.bin (TPL blob, as in the old working loader). DRAM init is correct, full
4 GB visible, Linux boots.
- U-Boot and DTS updated to v2026.01-rc5. Added MDIO/PHY node and phy-handle in rk3399-kobol-
helios64.dts, fixing “mdio node is missing”. Disabled i2s2 in the U-Boot DT to avoid rockchip-
i2s ... Could not register PCM.
- boot_targets in U-Boot config shortened (mmc1, scsi0, usb0, pxe, dhcp) to avoid env_buf ... too
small; however, the last built binary still shows the warning (needs rebuild with the shortened
list or enlarging the buffer).
- Boot flow: bootstd scans SD (mmc0) and eMMC (mmc1); SD boot works even without mmc0 in
boot_targets.
- Other changes: defconfig has CONFIG_ROCKCHIP_EXTERNAL_TPL=y to use the external DDR blob.
Boots.
