PN7462 custom board, problem with RF field on with NFC Cockpit. I designed my own board with PN7462. It based on development kit OM27462CDK. My schematic is in attachment. I have som FW to EVB when board is login into windows as COM port. this same FW I flashed to my board. When I tried to turn on RF field i gave erro message that RF field cannot be turn on. But on oscilloscope I measured that field is on. In my schematic if i desoldered B4 than i dont have problem but of course when i tried measure field was off.
Hi Lukas,
Looks like the connection of TVDD_OUT is different from the EVB, Please refer to the following for details.
Please try to remove B3 on your board.
Hope that helps,
Have a great day,
Kan
