Hi,
There's a post from last year that asks almost the same question that hasn't received any answers: https://forums.xilinx.com/t5/Processor-System-Design/Zynq-Ultrascale-PMBus-monitoring-required/m-p/915563#M42904
I am searching for documentation on the PMBUS implementation, specifically what happens if it's left unconnected to any of the regulators (or if one wants to use regulators that don't implement PMBUS - does one have to take any special care with the alter pin?). Obviously I am willing to lose the power management options, but I'd really like to know where this part of the machine is documented.
Thanks in advance.
