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 !
