Hi ADI Engineers
I try to make my post clear and no more than 256 words:
I 'm working on the EVAL-AD1080Z-PRX board
I could (W)rite and (R)ead back registers' data but could not make the 32MHz clock running!
W 0x0001 to 0x01, R back to verify: 0x0001
W 0x303A to 0x23, R: 0x303A
W 0x0A20 to 0x30, R: 0x0A20
W 0x0826 to 0x31, R: 0x0826
W 0x5AFC to 0x39, R: 0x5AFC
W 0x0001 to 0x5F, R: 0x0001 : turning on the 32MHz clock
W 0x0020 to 0x50, R 0x0020 : starting 32MHz clock calibration
Then Read 0x0A. got 0x0000 --> 32MHz not running???
W 0x0000 to 0x5F, R: 0x0000 : turning off 32MHz clock
W 0x00E07 to 0x0B, R: 0x0Eo7 : sending pulses to GPIO
W 0x0002 to 0x10, R: 0x0002 : jumping to run mode
Check GPIO0, GPIO1, and LED's circuit with my oscilloscope: No pulses detected ---> 32MHz clock not running????
Mistakes in my Regs settings or a bad Eval board?
I was careful to avoid shorts, over voltage, and electrostatic discharges.
Thanks for every help and idea.
