Out of curiosity, does this board also support HS400? From a very brief
look this board seems quite similar to Rock 4 series boards, that do
support HS400.
In a word, no, unfortunately. In more detail, the Rockchip RK3566
and RK3568 SoCs support the eMMC modes up to and including HS200, but
not the HS400 mode.
