Chipset-Command

Command:	memaccess   -   type Exec	Wiki	Freetz	IPPF	whmf	AVM	Web
Location:	Shell-Commands >> Chipset-Commands   -   Origin: Broadcom
Path:	Release: /bin Lab+Rel: /bin
Properties:	Size: 5.1k - 9.5k   -   Firmware: 6.54 - 7.31
Function:	Low-level access to the Broadcom chipset memory.

Goto:   Dependencies   -   Model-Matrix   -   Symbols   -   SMW-Browser

Details

memaccess is a multi-call binary providing low-level access to the BCM63 chipset memory using the brcmboard device.
It is typically only called by symlinks located in /opt/scripts and lists an overview if called directly:

7581 fw 7.17:

root@fritz:/var/mod/root# memaccess

*** Usage:

 dw/dh/db <physical address in hex> <number> 
 dw/dh/db <-k> <virtual address in hex> <number> 
 sw/sh/sb <physical address in hex>   .. 
 sw/sh/sb <-k> <virtual address in hex>   .. 
 fw/fh/fb  <physical address in hex>  <length> 
 fw/fh/fb <-k> <virtual address in hex>  <length> 

 -s (currently works with physical addresses for d*/s*/f* commands
     and virtual addresses for s*/f* commands)

• d* commands dump memory, s* commands store to memory, f* commands fill memory
• *w commands handle 4-byte words, *h commands handle 2-byte values, *b commands handle single byte values
• Option -k or --kernel means kernelspace.
• Option -s or --swap means swapspace.

The source could not be located on the GPL-Browser but here is a likely older source.
