I am trying control the hmc7044 evluation platform through an fpga over spi 3 wire.
I have followed the data sheet as a refernece and all the spi signals look similar to th small usb hittiie interface as compared in a scope.
But, i get no success be aus in my case hmc does not respond it always return me FF.
I always perform a soft reset and try to write and read the same register.
MY question is bout hard reset on pin 5 of hmc. do i really need to perform the hard reset before starting spi communication. this pin is connected to the ground on card by default but this pin acceseble at the small connector for us interface.
please let me know.
thanks in advance.
