Can somebody please explain what is exact
command to switch FreeBSD's serial console
speed to the 1.5Mbps as required by ROCK64 board?
I have u-boot interrupted from auto-loading
and trying to boot FreeBSD via network manually
by typing this:
=> dhcp
tftpboot ${kernel_addr_r} boot/loader.efi
tftpboot ${fdt_addr_r} boot/dtb/rockchip/rk3328-rock64.dtb
bootefi ${kernel_addr_r} ${fdt_addr_r}
After that I can see the FreeBSD loader's menu,
but then kernel hangs during loading.
Is the fact that I can see FreeBSD loader's menu is enough
to ensure that kernel will also inherit and continue use
the correct baud-rate?
How can I be sure that FreeBSD kernel when loaded
will continue to use 1.5Mbps speed or this is not supported
and I have to switch u-boot to something standard (115200)
somehow? If so - how?
thanks in advance,
Denis.
