Gpio; Mii_Mgr - Ralink RT2880 User Manual

a. read: flash -r [offset(hex)] -c [num of bytes]
b. write: flash -w [offset(hex)] -o [value(hex)] -c [num of bytes]
c. erase: flash -f [first sector_num] -l [last sector_num
Example:
a. read: flash -r 370000 -c 4
b. write: flash -w 370000 -o 1234 -c 4
c. erase: flash -f 60 -l 61

8.1.4 GPIO

Description: GPIO test program
Usage: GPIO [r/w/i/l]
The name of the GPIO testing user application is "gpio".
gpio w: writing test (output)
gpio r: reading test (input)
gpio i (<gpio>): interrupt test for GPIO number
gpio l <gpio> <on> <off> <blinks> <rests> <times>: set led on <gpio>(0~24) on/off interval,
no. of blinking/resting cycles, blinking time
Pin sharing scheme
It is important to know what normal function pins are shared with the GPIO pins. Only one
normal function and GPIO can operate at the same time.
GPIOMODE: GPIO purpose select)
Configure the pins to use as GPIO.
PIODIR: programmed I/O direction
Configure the direction of all GPIO pins to use as GPIO.
an output is set as '1', and an input pin is set as '0'.
PIODATA: programmed I/O data
Write data for output GPIO pins, and read data for input GPIO pins. PIOSET, PIORESET,
PIOTOG are also used for adjusting GPIO data bits.
PIOINT, PIOEDGE, PIORENA, and PIOFMASK should be set when using GPIO pins for input
that causes an interruption.

8.1.5 MII_MGR

Description: mii register read/write test program
Usage:
a. get: mii_mgr -g -p [phy number] -r [register number]
