Atheros SDRAM Configuration File Generator

## NAME

sdram - Atheros SDRAM Configuration File Generator

## SYNOPSIS

**sdram**

## DESCRIPTION

The Atheros SDRAM Configuration File Generator creates two INT6300 SDRAM configuration files in the current working folder. Either of them may be used as the argument for the **int6kf** **-C** option when initializing INT6300 devices. Read the **int6kf** man page for more information.

This program is part of the Qualcomm Atheros Powerline Toolkit. See the **AMP** man page for an overview and installation instructions.

## BACKGROUND

Configuration files for the Linux Toolkit have **.cfg** extensions and consist of 32 binary bytes plus a 32 bit checksum. They are difficult to modify but easy to verify. The format requires no conversion on input or output and, consequently, it is preferred to that used by the Windows Device Manager.

Configuration files for the Windows Device Manager have **.config** extensions and consist of 64 hexadecimal ASCII characters. They are easily modified using a text editor but cannot be easily validated. They require ASCII to binary conversion on input and binary to ASCII conversion on output. Read the **config2cfg** man page for more information.

## OPTIONS

- There are no options.

  ## EXAMPLES

The following example writes two files, **sdram16mb.cfg** and **sdram64.cfg**, in the current working folder. They will replace any existing files having the same names.

    \# sdram\
     writing sdram16mb.cfg\
     writing sdram64mb.cfg

## DISCLAIMER

The SDRAM file structure and content is proprietary to Qualcomm Atheros, Ocala FL USA. Consequently, public information is not available. Qualcomm Atheros reserves the right to change the file structure or content in future firmware releases without any obligation to notify or compensate users of this program.
