chapter 3.2 Power sources：
VDD5V—Input to the internal LinRegs. It can also be used to source the internal DC-DC with the
4.2 V regulated by the 4P2 LinReg. The 5-V source can be taken from a universal serial bus (USB)
connection, a wall charger with 5-V output, or a 5-V regulated from a supply with higher voltage.
There is a 100-mA input current limit when the system is powering up from the Power-Off state.
Product designers should pay attention to ensure the 100 mA is sufficient for the total system
consumption during cold-boot or reboot.
chapter 4.1.2 VDD5V source only：
Additionally, special consideration is needed for the hardware design in this configuration as the i.MX28
PMU is running on internal LinRegs on startup. The internal LinRegs have the following limitations:
• During the early stage of device startup, before on-chip ROM execution, the input current on
VDD5V is limited to 100 mA.
• The device is running on internal LinRegs on power up, and it needs to wait for the software to set
up the 4P2 rail before switching to the DC-DC converter as the power supply. The output current
from LinRegs is much lower than that of the DC-DC converter
I check the imx287 reference Schematic diagram 。I do not find the hardware design for limited to 100mA ?
how i deal with the limited 100mA for start up in hardware design ?
