Re: Assembly files and 'ORG' statement

I'm using the assembler to build raw data into a .tbin so that I can 
have this data accessible from flash.  I was finally able to solve my 
problem with the '-d' option.

Now, (as soon as the email shows up on the list), I have another 
problem with DataPort.  When I try to read from address 0x4a0000, I get 
an IllegalAddressException.  I'm trying to access the data I put there 
with the .tbin I just built.  When I write my own memory read routines 
with assembly, I can access 0x4a0000 just fine, but DataPort seems to 
dislike this location.  What are your suggestions?

Thanks,
	-Shawn
