One character is one byte, or 8 bits. mdh displays half-word, or 2 bytes, or 16 bits. > >> >> Did you suceed to halt your processor ? If yes, how ? Where was your error >> ?

I do not get it... Do you use OpenOCD to debug your programs ? If you use mwh, etc, I guess you do, so did you halt a processor with OpenOCD ? Again, did you configured well your SDRAM controller ?
