Instructions to use the Armadeus Bootstrap utility

Introduction

Bootstrap utility is a Perl piece of code that allows you to interactivly communicate with the iMX processor while in bootstrap mode. To enter bootstrap mode, you have to put the bootstrap jumper and restart your Armadeus board:

Launch

Go inside the boostrap folder (software/boot/bootstrap/) and launch (for example)

$ sh runBootstrap.sh --speed=38400 --device=/dev/ttyUSB0

if you're on Linux or

> runBootstrap.bat 

if you're on Window$

Boostrap tool will then try to synchronize with iMX:

Initializing serial port to 19200 bps
Re-synchronizing...
Please reset your board in bootstrap mode !
Please reset your board in bootstrap mode !
Please reset your board in bootstrap mode !
Please reset your board in bootstrap mode !

When you see that message reset your board.

If nothing happens, verify your bootstrp jumper is put and try to reset your board. At last check you serial port device is the right one and don't forget to quit kermit before launching Bootstrap tool !

Fisrt thing to do when entering bootstrap is initializing your SDRAM controller if you want to use it:
