hello
I want to ask about AFE4403EVM .
I bought AFE4403 EVM a few days ago, and used it first on yesterday.
But there were some problem about EVM
At first, it works normally about 30 mins, and I checked my ppg signal.
but suddenly, a error message at EVM GUI apperared that "cannot connected the board ~~"
so I disconnected the board to my laptop, and reconnected it.
but it didn't recognized at my laptop (not appeared the port at device manager) again.
Additional, i checked the led light on the board when it works normal, but led also turned off.
I checked the clock signal of AFE4403 chip, but the clock output signal not sensed with my oscilloscope.
I think there are some faults of the board because I just used it only 30 mins with default setting of GUI
So I want to ask you that is it possible to exchange or repair about this board.
(When i ask about it to my purchase site and ti Korea, they need the opinion of technical support)
I attached my clock signal output and captured picture of my device manager window.
Please let me know is there any other ways to solve this problem
Best regards,
Surin
