No effect on PS_POR_B Ultrascale

Hello,

Even If I pull up PS_SRST_B a push button low on PS_POR_B doesn't erase the PL bitstream (xczu15eg-ffvc900-1-e).

I have to put PS_SRST_B low to erase the PL bitstream then the Bootloader restarts over the QSPI.

So what is the use of PS_POR_B ? is that normal ?

Hi @jhouee ,

The PoR is Power on Reset and when it asserted, then the whole device get reset and it will start from the beginning.

please check the ug1085 for more details about PoR.

 

Best Regards,

Srikanth
