Yes, your log is ok. I tried to follow your way(dtb + uImage) to figure out why your kernel was hanging there, but no luck. You can find my log from [1] . (since my uImage is bigger than yours, i change the loadaddr to 0x90300000, 0x90306000) but there are some points we can check: - kernel config, you can find my config in [2], could you share yours to me as well, i can based on your configs to test. - uImage size (yours 1593664 bytes is quite smaller than mine, 2072864 bytes the difference based on kernel config and rootfs size) - cross tool chain (upload my toolchain to google drive [3]) - could you add initcall_debug to your bootargs, to see more log at kernel startup [1] kernel log based on dtb + uImage https://drive.google.com/file/d/1wnA5b3B_6MIb4PWZXn-3DlBbxpi41uSA/view?usp=sharing [2] kernel config https://drive.google.com/file/d/1oOJt3NRYor3-Uzjpzrujv3uvWguxYQQp/view?usp=sharing [3] arm-none-eabi- toolchain https://drive.google.com/file/d/1Aq0sF2Gi4y4qaDPnM2S0xCOowFSLZYJm/view?usp=sharing Best Regards Dillon > > > > > >> U-Boot > > >> U-Boot > > >> U-Boot > setenv loadaddr 0x90400000 > >> U-Boot > loady > >> ## Ready for binary (ymodem) download to 0x90400000 at 115200 bps... > >> CxyzModem - CRC mode, 156(SOH)/0(STX)/0(CAN) packets, 7 retries > >> ## Total Size = 0x00004cad = 19629 Bytes > >> U-Boot > setenv loadaddr 0x90406000 > >> U-Boot > loady > >> ## Ready for binary (ymodem) download to 0x90406000 at 115200 bps... > >> C- CRC mode, 12453(SOH)/0(STX)/0(CAN) packets, 4 retries > >> ## Total Size = 0x00185140 = 1593664 Bytes > >> U-Boot > bootm 0x90406000 - 0x90400000 > >> ## Booting kernel from Legacy Image at 90406000 ... > >> Image Name: Linux-5.13.0-rc1-00082-g9dbbd5cb > >> Image Type: ARM Linux Kernel Image (uncompressed) > >> Data Size: 1593600 Bytes = 1.5 MiB > >> Load Address: 90008000 > >> Entry Point: 90008000 > >> Verifying Checksum ...
