NAME
eepromer - reads and writes 24Cxx EEPROMs connected to I2C serial bus. SYNOPSIS
eepromer [-r|-w|-e|-p] -f <device> <i2c-addr> DESCRIPTION
The EEPROM must be a large EEPROM which uses a 2-byte address field (24C32 or larger). It will NOT WORK on small EEPROMs (24C01 - 24C16) such as those used on SDRAM DIMMs. NOTE
Don't forget to load your i2c chipset and the i2c-dev drivers. Tested only on 24C256. PARAMETERS
Actions -r Read -w Write -e Erase -p Print header Bus -f device Device file representing the I2C bus (eg. /dev/i2c-0) i2c-addr I2C bus address of the EEPROM (eg. 0x3A) SEE ALSO

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). SEE ALSO
