.SH DESCRIPTION
|
||
|
.PP
|
||
|
\fIeepromread\fR is a simple tool for viewing the contents of an EEPROM.
|
||
|
For EEPROM data that is in a specific format that this program knows how to
|
||
|
detect, \fIeepromread\fR can properly format each of the fields and display
|
||
|
the information via the \fI-i\fR command line option.
|
||
|
.SH NOTES
|
||
|
If the \fIcat24c256\fR driver has claimed the EEPROM device that this
|
||
|
program is attempting to read from, then this program will fail. Once
|
||
|
a driver claims an I2C device, the driver has exclusive access.
