Would you please present the FMEA about if only out of the power supply to the iMX6 1 strains unbootable due to power failure.
Specifically, do not supplied just below power line.
Or lower operating voltage range .
Please tell me failure modes of i.MX6.
VDDARM_IN
VDDARM23_IN (if the Quad Core)
VDDSOC_IN
VDDHIGH_IN
NVCC_DRAM
DRAM_VREF
NVCC_EIM0-2
Solved! Go to Solution.
Hi Takashi
processor will not boot if any of these power supplies
(except DRAM_VREF) will not have proper voltages, as
this is required by power - up sequence. When POR is deasserted
all power supplies and clocks should be applied according to datasheet
requirements. I think some kind of failure analysis can be found in
Chapter 8 "Avoiding Board Bring-up Problems"
