WinCE: Sysconf

Introduction

Sysconf.exe is a command line tool recommended for advanced system debugging. The tool enables access to the internal registers of PXA CPU and peripheral devices. Please consult the PXA Processor Developers Manual before using Sysconf.exe utility.

Sysconf Usage

SysConf Syntax

	SysConf  DA9030_ALL -to dump all DA9030 Codec registers
	SysConf  GPIO <pin number>      - to print all the relevant gpio data for the specified pin
	SysConf  GPIO <pin number> L<#> D<#> RE<#> FE<#> AF<#> - to manually set a certain pin with desired config args meaning:
                 L-Level(set=1/clear=0) D-direction(1 for output) RE-rise edge set AF- between 0-3
	SysConf  GPIO - to dump all GPIO registers
	SysConf  DEVICE <name> START - to activate a device
	SysConf  DEVICE <name> STOP - to activate a device
	SysConf  DEVICE <name> RESTART - to activate a device <name> - is the alias as specified in the documentation
	SysConf  ALLDEVICES - to print all active devices
	SysConf  ALLALIAS - to print all active devices with Alias name
	SysConf  NETIF  - to list all available network interfaces
	SysConf  NETIF <name> <cmd>  - to START/STOP/RESTART a network interface for example - SysConf NETIF WLAN1 STOP                       

The Sysconf tool is NOT case sensitive

Sysconf Usage Examples

• SysConf <RegName> - print register value.

- RegName - register name as defined in the PXA3xx documentation

- The following example will print GRER0 value:

> SysConf GRER0

• SysConf <address> - print value at the specified address

- address - address in the PXA3xx internal address space

- The following example will print the value of the GPLR0 register mapped at 0x40e00000:

> SysConf 0x40e00000

• SysConf GPIO <pin number> - print GPIO state

- Example:

 > SysConf GPIO 86
 Level=HIGH
 Direction=INPUT
 Rising edge=DISABLED
 Falling edge=DISABLED
 Edge transition NOT DETECTED
 AlternateFunction=0

• SysConf GPIO <pin number> [L<#>] [D<#>] [RE<#>] [FE<#>] [AF<#>] - set GPIO pin attributes
  • L - set GPIO logical state (low=0, high=1),
  • D - set GPIO direction (input=0, output=1)
  • RE - rising edge detection control (disable=0, enable=1)
  • FE - falling edge detection control (disable=0, enable=1)
  • AF - GPIO alternate function (values are from 0-3)

- The following example will configure GPIO 86 as output, logical 1, alternate function 0:

 > SysConf GPIO 86 L1 D1 AF0

- The following example will configure GPIO 86 as input, rising edge detection enabled, alternate function 1:

> SysConf GPIO 86 D0 RE1 AF1

• SysConf ALLALIAS - print all active devices that have an alias name.

An alias is defined in the registry value Alias in the BuiltIn registry key of the driver. The alias name is case sensitive and has to be in capital letters.

- Example:

1: WLN1: -> Drivers\BuiltIn\SPI, Alias=WLAN, key name is: 50
2: UFN1: -> Drivers\BuiltIn\Usbfn, Alias=USBFN, key name is: 39
3: COM3: -> Drivers\BuiltIn\Serial4, Alias=SERIALD, key name is: 35
4: COM2: -> Drivers\BuiltIn\Serial3, Alias=SERIALC, key name is: 30
5: COM1: -> Drivers\BuiltIn\Serial2, Alias=SERIALB, key name is: 29
6: SDH1: -> Drivers\BuiltIn\SDHC, Alias=SDCARD, key name is: 27
7: HCD2: -> Drivers\BuiltIn\PCI\Instance\OHCI2, Alias=OHCIITE, key name is: 26
8: NDS1: -> Drivers\BuiltIn\PCI\Instance\RTL81392, Alias=RTL8319, key name is: 25
9: HCD1: -> Drivers\BuiltIn\OHCI, Alias=OHCIPXA, key name is: 21
10: DSK1: -> Drivers\BuiltIn\NorFlashV3, Alias=NOR, key name is: 18
11: I2C1: -> Drivers\BuiltIn\I2C, Alias=I2C, key name is: 14
12: GIO1: -> Drivers\BuiltIn\GIO, Alias=GPIO, key name is: 11
13: DSK0: -> Drivers\BuiltIn\NandFlashV3, Alias=NAND, key name is: 02

• SysConf DEVICE <DevName> STOP - stop a device driver and unload it from the system.

- DevName - device alias name as displayed by the SysConf ALLALIAS command

- Example:

> SysConf DEVICE WLAN STOP

• SysConf DEVICE <DevName> START - load a device driver and start it

- DevName - device alias name as displayed by the SysConf ALLALIAS command

- Example:

 > SysConf DEVICE WLAN START

• SysConf ALLDEVICES - print all active devices that have a prefix name.

- Example:

1: TEL1: -> services\TELNETD\NewSession, key name is: 62
2: NTP0: -> Services\TIMESVC, key name is: 59
3: SMB0: -> Services\SMBServer, key name is: 58
4: TEL0: -> Services\TELNETD, key name is: 57
5: FTP0: -> Services\FTPD, key name is: 56
6: HTP0: -> Services\HTTPD, key name is: 54
7: UIP1: -> uiproxy, key name is: 52

• SysConf NETIF - print a list of all network interfaces.
• SysConf NETIF <IfName> <cmd> - change network interface state

- IfName - the interface name as displayed by the SysConf NETIF command

- cmd - can be STOP, START or RESTART

- The following example will disable WLAN1 network interface in the GUI:

> SysConf NETIF WLAN1 STOP
