[vmu] VMU and Flash ROM...   Message List  
Reply | Forward Message #47 of 1156 |
Hello.

I'm currently writing a program where I need to write data to the VMU
Flash Rom. Only problem, for some reason I can't write to addresses that
are not divisable by $100 (all addresses are within the VMU gamefile, of
course). Basically, this means writing blocks of 128 bytes of data to
addresses like $100, $200, $300 etc. works, but writing to addresses like
$180, $280, $380 etc. does _not_ work. But in the description about the
VMS Firmware it is stated that it's enough if the addresses are divisable
by _$80_.

So, any ideas what I might be doing wrong here? ;) I need to write a part
of _continuous data_, without gaps of 128 byte after each 128 byte of
data...

Or how about some short sample code that first writes data to an address
at .cnop 0,$100 and then at .cnop 0,$180 or something?

Bye


Alessandro

Ok, I've spotted what you're doing wrong. Somehow, you seem to have misunderstood the concept of big-endianness. The _most_ significant part of the address...
