PN7462 vcom doesnt show up after flashing Flash.bin/EEPROM.bin

Hello guys

After flashing my device over the mass storage it doesnt show up on the pc.  

I also have an evalboard but there is no Problem with the connection and the Vcom on the desktop.

Do I have to install another file to get it running.

Because I dont think that it is a Hardware Problem.

-> Windows 10

Yurs faithfully

Problem solved !!!

The mass area wasn`t soldered so the microcontroller was able to communicate only through the swd interface. But it didn`t function after the flash.

Hello fangfang

The chapter 5.3 (4.3) does not help me in the slightest because I am already able to Flash the PN7462.

The only Problem is that i can´t see the vCom on the PC after the flashing the two files "Flash & EEPROM" just as the evalboard.

I already checked the voltages and the Connections compared to the evalboard PNEV7462C.

I am using the PN7462AUHN and the following files:

….03_04_00_Flash.bin

….28_00_00_EEPROM.bin
