Dear team,


I would like to ask about power-on sequence for i.MX6Q.

After reading chapter 4 in your Hardware Development Guide for i.MX6Quad, my customer wants to know whether the following sequence, in the following order, can be allowed.

-  2.8V(VDDHIGH_IN) and 1.2V(NVCC_RGMII) are turned on simultaneously.

-  Then, 3.3V(NVCC_EIM0~2,NVCC_ENET,NVCC_GPIO,NVCC_SD3,NVCC_NANDF,NVCC_JTAG) and 2.5V(NVCC_CSI,NVCC_SD1,NVCC_SD2) are turned on simultaneously.

-  Then, NVCC_DRAM(1.5V) is turned on.


Could you show me whether the above is allowed?
