Write in EEPROM - Custom board based on AM335x starter kit.

I made a Custom  board based on AM335x starter kit.
It also has the EEPROM to read the card information.
But when using the U-BOOT it stop on message:

U-Boot SPL 2015.01 (Apr 28 2016 - 14:24:12)
Incorrect magic number (0xffffffff) in EEPROM
Could not get board ID.
Incorrect magic number (0xffffffff) in EEPROM
### ERROR ### Please RESET the board ###

But when I try to program the EEPROM following the link (processors.wiki.ti.com/.../AM335x_Starter_Kit_ID_Memory_Programming it stop too in the following message:

StarterWareAM335x Boot Loader
Copying application image from MMC / SD card to RAM
Jumping to StarterWare Application ...

In my board I put some resistors of 33ohm instead of 50ohm which are in AM335x Starter Kit.

I read this link (processors.wiki.ti.com/.../AM335x_EMIF_Configuration_tips) and I believe that I have to set the register (SDRAM_CONFIG.REG_DDR_TERM), but I can not run UBoot nor the app to write in eeprom memory.

I believe I have to modify the app to program the EEPROM and then, after that, change the UBoot.

My question is if the app (app - Test binary - processors.wiki.ti.com/.../AM335x_Starter_Kit_ID_Memory_Programming texas provides the source code?

Thank you
