Problem with eeprom of beaglebone black in my custom board

Hello,

I have implemented my new AM335x board recently which most of my schematic is the same as beaglebone black. The board eeprom is empty and at the boot moment I face these errors:

U-Boot SPL 2014.07-rc4-00015-g5bcd74d (Jul 04 2014 - 16:03:33)
Incorrect magic number (0xffffffff) in EEPROM
Could not get board ID.
Incorrect magic number (0xffffffff) in EEPROM
Could not get board ID.
Unknown board, cannot configure pinmux.### ERROR ### Please RESET the board ###

How can i write on eeprom at boot time? is there any specific tools for writing appropriate ID in that?
Please help with is issue…

What would happen if you went to the top of this page and searched this email forum for a topic like “beaglebone eeprom configure” ?

I think that would reveal a thread that was 41 emails long on the topic of “Cloning Beaglebone”.

Is this a BBB clone or a BBW clone? aka ddr3 or ddr2?

Regards,

Dear Robert,

Thanks for you reply. The board is the same as beaglebone black without HDMI part. I used DDR3 but about your question which is BBB clone and BBW … I do not know, I am quiet new in this area. Please tell me more if it possible. thanks.

Okay, since it's a beaglebone black clone with ddr3 you can use this:

Just dd/bmaptool it to a microSD card..

GND the wp of the board eeprom..

Boot the board, that image will program a default bbb eeprom..

Thanks Robert, that was great help. Now everything works well.
