ok. whats next?

Got it soldered there, programmed it with my i2ctool
and after faking TOH in place with takkatikku





i can see it in /sys/bus/i2c/devices/1-0050

Code:
[root@localhost 1-0050]# xxd eeprom
0000000: 1234 5678 0101 0000 3000 0500 4000 0600  .4Vx....0...@...

It appeared in /sys/devices/platform/toh-core.0

And there are all data except 'udata' ?
