I need to use NFC07A1 to power STM32l476RG, but the PIN 4 connecting CN6 according to the instructions failed to make the MCU run. I tried to write the LD2 flicker program, but the NFC power did not make the LD2 flicker after the USB power failure. But the LD3 power indicator of my L4 was already on, so why didn't I succeed in getting the MCU wirelessly powered? According to the instructions I find that the LD3 works as long as it is successfully lit. What do I need to do to make the EH output pin power the L4 operation?
