PN7462-Problem to Flash

sanath_rai — Thu, 19 Dec 2019 12:35:45 GMT

Hello ,

We are working on PN7462 NFC controller.we have been working on PNEV7462C development board which works fine now we have our custom borad 5Vinput voltage. Everything(schematics ,circuit design) same as the development board.but when we flash it using MCUexpresso IDE we are getting below error.what might be the issue?

What is the MCUXpresso version? What is the project you tried to download? Could you try to download as mentioned in 6.7 Updating Flash via SWD interface from UM10883? Please kindly clarify.

Have a great day,
Kan

Hi Kan_Li,

It got resolved. Issue was with IC placement on our custom board.

We removed the IC and replaced it .it works now.

New Issue

I am building my application on Door access application which works with 5V(VBUS )power supply in EVM board.

This application does not work for 3.3v in EVM board.

we have made changes according to UM10883 for 3.3 and 5v system.

Any particular changes to be made in software or hardware?

Regards,

Sanath Rai

Hi Sanath Rai,

Did you change VBUS option as below?

If yes, I also tried and it works well as expected.

The board version is PNEV7462B.

Have a great day,
Kan
