How to program mac address

Hi,

What tool/procedure should I use to store MAC address in data sector on W7500P board?
Any suggestions?

Thank you,

Julie

Hi.

  1. You upload firmware to W7500P (firmware file below link)

Source code: github.com/Wiznet/W7500x-Serial … net-device

ISP tool: wizwiki.net/wiki/doku.php?id=pro … load:start

  1. After firmware upload complete, access USB to UART module to UART2 pin. and then checking debug message.

  2. " input First MAC" message output from W7500P.

  3. then, “MC00:08:DC:xx:xx:xx” serial message trans to W7500P

It is save to W7500P flash memory.

Thank you

If you use the WIZwiki-W7500P board, you can’t program the MAC address.
Need a I2C eeprom IC: 24AA16T-I/OT, or other 24xx16 eeprom.

Thank you very much for your inputs.

Sorry.

I’m mistake.

refer to below link to download firmware code.

github.com/Wiznet/WIZ750SR

So, access the below root.

WIZ750SR/Projects/S2E_App/src/W7500x_board.h

And modify to below code.

//#define DEVICE_BOARD_NAME WIZwiki_W7500ECO
#define DEVICE_BOARD_NAME W7500P-S2E
//#define DEVICE_BOARD_NAME WIZ750SR

And retry.

Thank you
