Yes, it does still show eeprom
debian@beaglebone:~$ ls /sys/bus/w1/devices/23-02eddd9b
driver eeprom id name power subsystem uevent
debian@beaglebone:~$ ls /sys/bus/w1/devices/
23-02eddd9b w1_bus_master1
debian@beaglebone:~$
debian@beaglebone:~$ ls -al /sys/bus/w1/devices/23-02e
Thank you (and sorry for the double post) !
However, I still have no luck writing to the eeprom.
I have tried a couple of variations of the commands but I get error even if
logged in as root.
debian@beaglebone:/sys/bus/w1/devices/23-02eddd9b$ sudo sh -c "echo
'cat /home/debian/file' > eepro
I would need some help to understand why I can't write to an DS2433 eeprom.
System information:
BBB Industrial board
Debian 10 (Buster IoT Image 2020-04-06)
Hardware attached are DS2482 i2c to w1 interface and DS2433 eeprom.
Commands executed:
$ modprobe ds2482
$ echo ds2482 0x18 > /sys/bus/i2c/d
