Instructions to use the Armadeus UbootRecover utility


The uboot_recover tool is a Python piece of code that allows you to automatically install a new uBoot from scratch or to recover it in case of failure.
This utility communicates with the iMX processor while in bootstrap mode.
To enter the bootstrap mode, you have to put the bootstrap jumper and restart your Armadeus board:

Go inside the uboot_recover folder (software/uboot_recover/) and launch

$ python
  • The tool will ask you to specify the serial port on which the board is connected. Under Linux please use /dev/ttySx and under Windows use COMx
  • Then the size of the SDRAM has to be indicated. Default value is 16Mo.
  • The tool will then try to synchronize with iMX:
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 bootstrap 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 uboot_recover tool !

  • Then you can specify whether the environment variables (IP, your special scripts...) have to be erased or not. If your board does not start anymore after a first uboot_recover, please responds by 'y'
