After double checking some i2c addresses are not correct. It is visible from i2c dump ZynqMP> i2c bus Bus 3: i2c@ff020000 74: i2c-mux@74, offset len 1, flags 0 Bus 5: i2c@ff020000->i2c-mux@74->i2c@0 Bus 6: i2c@ff020000->i2c-mux@74->i2c@2 Bus 7: i2c@ff020000->i2c-mux@74->i2c@1 Bus 8: i2c@ff020000->i2c-mux@74->i2c@3 Bus 4: i2c@ff030000 (active 4) 74: i2c-mux@74, offset len 1, flags 0 Bus 9: i2c@ff030000->i2c-mux@74->i2c@0 Bus 10: i2c@ff030000->i2c-mux@74->i2c@3 Bus 11: i2c@ff030000->i2c-mux@74->i2c@4 Bus 12: i2c@ff030000->i2c-mux@74->i2c@5 (active 12) 51: generic_51, offset len 1, flags 0 60: generic_60, offset len 1, flags 0 74: generic_74, offset len 1, flags 0 Bus 13: i2c@ff030000->i2c-mux@74->i2c@6 (active 13) 51: generic_51, offset len 1, flags 0 5d: generic_5d, offset len 1, flags 0 74: generic_74, offset len 1, flags 0 ZynqMP> i2c dev 4 Setting bus to 4 ZynqMP> i2c mw 74 0 18 ZynqMP> i2c probe Valid chip addresses: 18 36 37 50 51 60 74 ZynqMP> i2c mw 74 0 20 ZynqMP> i2c probe Valid chip addresses: 51 60 74 where it is clear that si570 (u5) is at 0x60 address and 8t49n240 (u39) is also at address 0x60 based on log above. i2c address 0x74 is i2c mux and 0x51 is eeprom.
