i2c-stub-from-dump

I2C-STUB-FROM-DUMP(8)					      System Manager's Manual					     I2C-STUB-FROM-DUMP(8)

NAME

       i2c-stub-from-dump - feed i2c-stub with dump files

SYNOPSIS

       i2c-stub-from-dump address[,address,...]  dump-file [dump-file ...]

DESCRIPTION

       i2c-stub-from-dump  is  a small helper script for the i2c-stub kernel driver.  It lets you setup one or more fake I2C chips on the i2c-stub
       bus based on dumps of the chips you want to emulate.

       i2c-stub-from-dump requires i2cdetect and i2cset to be installed and reachable through the user's PATH. The former is used to find out  the
       i2c-stub bus number, while the latter is used to write to the fake I2C chips.

EXAMPLE

       You  have an I2C chip on system A. You would like to do some development on its driver on system B. Here are the few steps you have to fol-
       low.

       On system A, use i2cdump to capture a dump from the chip. Assuming that the chip in question lives at address 0x4c on I2C bus 0, you  would
       run:

	       i2cdump -y 0 0x4c b > chip.dump

       Adjust the bus number and chip address for your case. i2cdetect can help you find out their values. If the device uses word (16-bit) regis-
       ter access instead of the traditional byte (8-bit) access, use mode w instead of b.

       Copy the dump file to system B.

       On system B, run:

	       i2c-stub-from-dump 0x4c chip.dump

       This will load the required i2c-dev and i2c-stub kernel drivers if needed, then write all the register values to the emulated I2C  chip	at
       address 0x4c.  Again, adjust the address as needed.

LIMITATIONS

       There are some limitations to the kind of devices that can be handled:

       o      Device must not have banks (as most Winbond devices do).
