<h1>flash</h1>
|
|
<p>The flash command provides for programming, erasing and copying flash memory
|
|
areas.</p>
|
|
<h2>Format </h2>
|
|
<p>The format for the command is:</p>
|
|
<blockquote>
|
|
<pre><font size="+1">flash [-q] [-e arg] [args ...]</font></pre>
|
|
</blockquote>
|
|
<pre>where:

<table width="86%" border="0">

|
<p>Each area in the flash devices will be identified, and is dependant on the
|
|
system implementation. </p>
|
|
<p>These areas are useable for storage or for bootable images.<br>
|
|
The -q (Query) option will list each system dependent flash ROM area. The base
|
|
address and size is listed, along with each flas area configuration, sector
|
|
size (if supported) and the actual Flash device Manufacturing ID value (if reported).
|
|
Example:</p>
|
|
<pre>PMON> flash -q
|
|
Available FLASH memory <br> Start Size Width Sectorsize Type
|
|
ff000000 00800000 8*8 00040000 i28F160
|
|
fff00000 00080000 1*8 00010000 Am29F040
|
|
PMON>
|
|
</pre>
|
|
<p> The -e (Erase) option code calculates the sector from the flash address you
|
|
enter, and the number of sectors are the size divided by sectorsize (rounded
|
|
up).<br>
|
|
</p>
