Details
nvramUpdate updates the nvram in Broadcom models from a (ASCII or binary) file. It is not used by the system.
The binaries are SoC specific and typically located in /etc/wlan, see the Examples below.
7581 fw 7.17:
root@fritz:/var/mod/root# nvramUpdate -h
Usage:
nvramUpdate [-m] [-s tftpdserver] [-h] {DataFileName | Recover | Read | Show | Clean | Feature}
==============================
-m: Option -m for {Clean} and {Data} indicate manufacture automation to bypass prompt
-s: Option -s tftpdserver where nvram map binary file are loaded from
-d: Option -d to specify where the nvram map binary to put on system, default to /etc/wlan
-h: Option -h for help
==============================
Clean: Clean up Nvram
Read: Read back Calibration data in binary format
Show: Read back Calibration data in input ASCII file format
Recover: Copy all nvramMap .bin from backup to /etc/wlan
Feature: Get/Set wl feature settings
DataFileName: Nvram data file name,when ended with ".bin",it indicates as a complete nvram MAP
it will be loaded to /etc/wlan or the directory where -d is given, if file name is
not ended with ".bin",it will be partial change and formated as:
###################
ID=pci/bus/slot/ Or
ID=pci/domain/bus/slot/
offset1=value1
......
ID=pci/bus/slot/
offset1=value1
......
offsetn=valuen
###################
Example: 52=38fc
value is 16bit hexical data
Offset is decimal, 16bit aligment offset(not 8bit alignment offset)
The ID will print in console when driver load
