Bootloader Command Reference
- Albinleo Velappan (Deactivated)
The Seco-bootloader for Trizeps-modules supports many different commands to:
Update/Modify the flash-contents ( bootloader, WinCE-Image, registry,…).
Modify hardware registers or memory.
Test Trizeps functionality.
Modify boot-behaviour.
Boot from different devices.
These commands may be used in a boot script ( autoboot.bat).
Not all commands are supported on all modules.
You enter the bootloader by using a Hyperterminal:
Connect your Trizeps-module with your PC using a serial-cable (level-shifter like max232 needed).
Open Hyperterminal (or similiar program) with 38k4 Baud, 8 Bit, No Parity, 1 Stop-bit.
Press <ESC> while powering up the Trizeps.
Now you should see the boot-prompt.
Numbers can be entered in decimal or hexadecimal. If 0x is preceeding a number hexadecimal is assumed.

Bootloader Device Interface
Usable in Trizeps4/5 bootloader.
The bootloader device interface allows a more generic way of handling devices integrated in the bootloader.
devices
List all known devices.
Usage: devices
device
Set the current active device on which other device-interface-commands should act on.
Usage: device <device-name>
open
Open device. This initializes the specified device.
Usage: open <device-name>
close
Close device. This deinitializes the specified device.
Usage: close <device-name>
probe
Probe if device is present.
Usage: probe <device-name>
reset
Reset device.
Usage: reset <device-name>
read
Read from the current device. i.e. capture bytes from COM-port.
Usage: read <address> <number of bytes>
write
Write to the current device. i.e. output bytes on a COM-port.
Usage: write <address> <number of bytes>
seek
Set the file-pointer of the current device. i.e. when using flash or memory-cards.
Usage: seek <new position>
help
Display help on the current device. Typically variables of the device are shown.
Usage: help
set
Set variable of the current device.
Usage: set <variable-index> <new value>

Usage: monitor <device-name>
setbaud
Set baudrate of the specified device.
Usage: setbaud <device-name> <baudrate>
Filesytem and Storage-Card functions
There are two different interfaces.
These functions are used with the newer bootloader-device-intferface:
mount
Mounts volume of specified device.
Usage: mount <device-name> <volume-number: 0 is default>
boot
Boots a file from mounted volume.
Usage: boot <device-name> <filename>
dir

Special Commands
These commands are not visible in the command-list.
Consider them as not documented.

Usage: .noflash
.storeburn
Used in conjunction with a deployment-board. The deployment board is board capable of flashing multiple Trizeps-modules at the same time. It indicates success/failure of update procedure through the LED's of the board.
