RK3288 Hardware Design Guide
9 Flash control & Memory
9.1 Schematic
RK3288 supports Nand Flash, eMMC and tSD, etc. If Nand Flash, tSD Flash is used,
controller and its power supply VCC_FLASH should be 3.3V (R1300 is NC as shown in Fig 9-1).
For eMMC in different versions, controller and its power supply VCC_FLASH may be 1.8V
(eMMC4.1 above version) or 3.3V, please adjust it based on Datasheet, and verify
FLASH0_VOLTAGE_SEL pull-up and pull-down status as shown in Table 9-1.
Tips：
When eMMC is in use, suggest to power supply VCC_FLASH 1.8V, which will stabilize
high-speed operation;
FLASH 1 channel doesn’t support eMMC Flash;
Boot booted by FLASH 0 channel as default, which can’t be modified.
