Hi Bishnu, Is your design "big"? I have found it easy to overwhelm the power supplies of the 4x2 with a large design, at which point they automatically shut down, and the board becomes unresponsive to both ping and casperfpga commands. If I remember correctly, if this happens there are some error LEDs on the board which will light up. I've also found that putting a bigger heatsink on the board can buy a little more margin.
Assuming your board's OS has the appropriate I2C drivers, if your issue is power related, you may find this script useful - https://github.com/realtimeradio/souk-firmware/blob/main/software/rfsoc_scripts/get_power_sensors.py If you run it on the board, it will report the current drawn on each of the power rails.in my experience, the board will shut down once 0V85 current draw gets near 100%. If you are only running small firmware, then I suspect your issue is something else.
