Hi Team,

For the PWRONRSTn in the AM4378 is there any timing requirement need to be met like minimum delay from the stable power supply/clock and Reset pulse width. Please confirm

    See notes in the power sequencing diagrams in section 5.12.1.2 of the datasheet.  During initial power up, the only requirement is that the PWRONRSTn remains active low  throughout power supply ramp and until the high frequency system clock is stable.  Figure 5-11 shows the startup time for the oscillator at a min of 1.5ms
