Hello
Please see my comments
#1. slave fault shutdown and sequencer off dependences are two irrelevant. it is application's responsibility to set these to ensure dependencies are met.
Since rail#5 has turn off dependencies on rail6/7 you have to…
Hello
Since this is a Xilinx design, please contact them for any platform/hardware support.
From the system monitor, there is over voltage warning on the rail#1. but there is no fault on the system.
rail#3 and rail#4 are not power up. there are…
Hi
You may mix the Logic controlled GPO(LGPO) with the rail ENABLE. Normally we do not recommend to use LGPO as ENABLE to control the power rail unless you run out of the ENABLE.
UCD has a dedicated ENABLE feature to control power rail.
Please refer…
