i2ctool

The i2ctool allows testing of the devices on the i2c bus.

In EDA Quick Test mode, i2ctool scans busses and identifies all of the devices. If a device is behind a MUX, i2ctool looks for devices

through the MUX and, if present, a second-level MUX as well.

Example of the i2ctool Ouput

Syntax: ./i2ctool <option>

-h := show this help

test := test <user_i2c_file.cfg> the pre-programmed configuration

# ./i2ctool test userI2cFile.cfg

read := read I2C device with <bus> <dev> <address> <bytecount>

# ./i2ctool read /dev/i2c-0 0x50 0x00 10

write := write I2C device with

# ./i2ctool write /dev/i2c-0 0x50 0x00 0x0a 0x0b 0x0c

scan := scan <bus_prefix> the I2C devices on the specified bus prefix

# ./i2ctool scan /dev/i2c-

memtool

The memory tool (memtool) tests system memory.

EDA Quick Test mode only completes simple access (read) tests. You can use memtool to test static memory areas, such as L2Cache

mapped as SRAM or DRAM on a memory mapped device.
