Quote:I believe on the Quartz64 that if there is both an eMMC module and a microSD card then it boots the microSD card.your belief is in opposition to what rockchip has documented in their TRMs, they released. eMMC gets checked before SD. if there is ID BLOCK there, how they call it, the ROM code picks this medium. that means, in your scenario, given both have valid uboot installations (ROM code payload), eMMC will be chosen.
