This memory is different from the HY57V561620 and MT48LC16M16 types I know and 
Barebox is adapted to.

Maybe your system doesn't come up due to a wrong SDRAM configuration.

You should compare the SDRAM datasheets and check if the SDRAM controller 
settings in Mini2440 'config.h' match the requirements of your SDRAM type.
