AWR1642: Power up sequence on AWR1642EVM

Part Number: AWR1642
Other Parts Discussed in Thread: TPS7A8101,

Hello team,

On the AWR1642boost EVM, with LP87524B+TPS7A8801+TPS7A8101 power solution.

When testing the power up sequence, customer found the 1.8V on device side is not ready while the NRST release. On below picture, the 1.8V is ready afther the NRST release 60ms. 

But this EVM work normally, can you please provide an explain on this power sequence. do the 1.8V need to be stable before the NRST release?

Thanks.

Wesley
