According to the loco_node_revd.pdf. I finished my pcb and test . But find some problem . Failed to read data from EEPROM! Can tell me how to solve it?

Help
-------------------
0-9 - set address
a - anchor mode
t - tag mode
s - sniffer mode
m - List and change mode
d - reset configuration
h - This help
---- For machine only
b - Switch to binary mode (sniffer only)

From what I understand from the code, you should type d and reset your board.
This will write a 1 on adress 0 in the EEPROM, which is then tested in the self-test.

Give it a try

why my eeprom can't work ... is 24AA64f sot23?

There seems to be a connection problem with the EEPROM. The EEPROM is a SOT23-5 chip.

Has this node ever worked?

thank you ! you help me find my pcb connection problem!
