Other Parts Discussed in Thread: TPS65224
Tool/software:
Use the TPS65224 power supply to power the AM62A7. The power-on timing of OSC and VDDR_CORE(0V85) voltage as measured is shown in the waveform diagram.
In the AM62A7 manual, the overall power-on timing diagram is as follows. It can be seen that the oscillation start requirement for the OSC occurs after the CORE power is fully powered on.
In the description of the OSC section, it means that the crystal should be able to oscillate normally 4ms after the CORE power is turned on. So I understand that in the power-on timing diagram, the illustration that requires the crystal to start oscillating again after the CORE is powered on is the same as what is stated in the OSC section. I hope this can help clarify the above viewpoint. Thank you for your assistance!
