I have an ADE7953 evaluation board (rev C), and i have an issue reading the registers, I can connect to the chip with the software since the comm Port is found and it seems that I can reset (I see led D5 blink but not D6 and D4) but when I access the registers they're all with a value of FFFF except for CRC with 0. It all worked well a few hours ago and since I've came back I can't read anything, do you have any idea of why I have this problem ?
Thank you in advance,
Could you power everything down and reboot. You usb ports may have entered and power down state.
Does the board reconnect?
Can you measure:
Yes that's one of the first things I did, and the board reconnect, same problem. For the measures I have :
reset_n : 3.3 V
VintD : 2.522 V
VintA : 2.593 V
Vdd : 3.3 V
REF : 1.199 V
can you probe the comms ( spi or i2c or uart) you are using and see if you have activity?
