以上是开机内存检测信息，双通道正常。

U-Boot 2017.09-g6999767 (Oct 08 2019 - 23:24:18 -0700)
Model: Rockchip RK3399 Evaluation Board
PreSerial: 2
DRAM:  3.8 GiB
Sysmem: init
Relocation Offset is: f5bd9000
Using default environment

DRAM:  3.8 GiB，与检测到的内存不符，不知道怎么解决？谢谢

备注：Channel 0:焊接 4GB内存芯片，Channel 1 不焊接，检测正常（DRAM:  3.8 GiB）
