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...

Regards
Masoud

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?

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..
