Request for Application Note AN3638

[leavs]

Hi,

I'm using my custom LS1046A board.

I want to use EEPROM to store MAC address.

From the source code

uboot/board/freescale/common/sys_eeprom.c

I know there is one application note AN3638 to know the detail of EEPROM layout for CCID or NXID formats.

Can you share it with me?

And is there one Userland Application source code to access the EEPROM to write this EEPROM by using the CCID or NXID formats.

Thanks.

Sorry, could not find the Userland Application source code.

Please find https://www.nxp.com.cn/docs/en/application-note/AN3638.pdf

In the uboot use the command "i2c md 0x53 0x40 0x100" in LS1046ARDB, you could read the inform.

You could use uboot i2c command to change the IDs.

Thanks for your link.

Do you have one userland application to access this EEPROM?
