Hello, I'm running into problems trying to get the official upstream nanopc-t4-rk3399_defconfig to work on my NanoPC-T4. I'm building u-boot on Ubuntu/Focal (docker container) as follows:
# cd /root # apt-get update # apt-get install build-essential flex bison gcc-aarch64-linux-gnu git device-tree-compiler python3 gcc-arm-none-eabi bc # git clone https://github.com/ARM-software/arm-trusted-firmware.git # cd arm-trusted-firmware # make realclean # make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 # export BL31=/root/arm-trusted-firmware/build/rk3399/release/bl31/bl31.elf cd /root # git clone https://github.com/u-boot/u-boot.git # cd u-boot # make CROSS_COMPILE=aarch64-linux-gnu- nanopc-t4-rk3399_defconfig # make CROSS_COMPILE=aarch64-linux-gnu- After the successful build, I copied idbloader.img and u-boot.itb to my NanoPC-T4 and attempted to install them like so: # dd if=idbloader.img of=/dev/mmcblk2 conv=fsync,notrunc bs=512 seek=64 # dd if=u-boot.itb of=/dev/mmcblk2 conv=fsync,notrunc bs=512 seek=16384 After installing, the boot process never makes it to a login prompt. In order to get the dmesg output, I connected to the machine via UART, and I captured the following logs: https://gist.github.com/tmountain/f3fd939dece80aaeb069c28db7d54e3d Please advise if I'm doing something wrong. I am available to assist with testing if necessary. Thanks, Travis
