This is output from Rockchip's binary-only loader, which always resets
the UART speed to 1.5Mbps. But it should be running before the U-Boot
SPL, not after it.
How are you building the microSD-card image? Here are the commands I've
been using to build working images for the ROCK64:
Building U-Boot (note this will overwrite your configuration with the
contents of the defconfig file):
make distclean; rm -f idbloader.img
make rock64-rk2238_defconfig all u-boot.itb
Assembling an image with the Rockchip loader:
tools/mkimage -n rk3328 -T rksd -d
~/src/rockchip-linux/rkbin/bin/rk33/rk3328_ddr_333MHz_v1.16.bin
idbloader.img
cat spl/u-boot-spl.bin >> idbloader.img
Writing it to the microSD card:
sudo dd if=idbloader.img of=/dev/mmcblk0 seek=64
sudo dd if=u-boot.itb of=/dev/mmcblk0 seek=16384
