Hi Martin,
thanks for your answer.
I realized with dmesg that my board is detected as BBB. 
The version.sh output is not very clear due to not ascii characters, but 
seems different
from the ones printed on my beagleobones sticker.

git:/opt/scripts/:[d36fe9a7be9ebfc872b10a470e904ab4c61c4516]
]eprom:[A335BNLT°O
dogtag:[BeagleBoard.org Debian Image 2017-10-10]
bootloader:[eMMC-(default)]:[/dev/mmcblk1]:[U-Boot 
2017.09-00002-g0f3f1c7907]
kernel:[4.4.91-ti-r133]
nodejs:[v6.12.2]
uboot_overlay_options:[enable_uboot_overlays=1]
uboot_overlay_options:[uboot_overlay_pru=/lib/firmware/AM335X-PRU-RPROC-4-4-TI-0
0A0.dtbo]
uboot_overlay_options:[enable_uboot_cape_universal=1]
pkg:[bb-cape-overlays]:[4.4.20171215.0-0rcnee1~stretch+20171215]
pkg:[bb-wl18xx-firmware]:[1.20170829-0rcnee1~stretch+20170829]
pkg:[firmware-ti-connectivity]:[20170823-1rcnee0~stretch+20170830]

Now, as written on link you suggested, I need to rewrite eeprom with BBBW 
data.
It is reported to ground TP1 before the dd command, but by schematic WP of  
CAT24C256W 
is connected with a resistor to VDD (write protect fixed), and TP1 is just 
a DGND.
How did you rewrite the eeprom? Forcing WP signal to DGND?

Regards

Renato
