The driver attempts to support all documented parts, but has only been tested with the 512Mbit part on the Terasic DE4 FPGA board. It should be trivial to adapt the driver's attach routine to other embedded boards using with any parts in the family. Also import isfctl(8) which can be used to erase sections of the flash.

|
|
.Ic erase
|
|
.Ar offset
|

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility provides a way for administrators to control aspects of
|
|
.Xr isf 4
|
|
devices that can not be managed though the
|
|
.Xr disk 9
|
|
interface.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility takes a device name as its first argument followed by a command.
|
|
Currently supported commands are:
|
|
.Bl -tag -width erase
|
|
.It Ic erase
|
|
Erase blocks beginning at
|
|
.Ar offset
|
|
covering a total of
|
|
.Ar size
|
|
bytes.
|
|
The
|
|
.Ar offset
|
|
argument must be a multiple of 128K.
|
|
The
|
|
.Ar size
|
|
argument must either be a multiple of 128K or a number less than 32K in
|
|
which case it is treated as a number of 128K blocks to erase.
|
|
.El
|
|
.Sh EXAMPLES
|
|
.Dl isfctl isf0 erase 0 0x20000
|
|
.Pp
|
|
Erase the first block of the isf0 device.
