I read some topics about placing a const to fixed address by linker. The method is to locate all section, isn't it? My problem is to locate 7 arrays of const(predefined): a1[50]..a7[50]. I want to place a1[] at 0xC07D00, a2[] at 0xC07E00, a3[] at 0xC07F00 and etc. So, how i can do it? Is it true that theese arrays will be united in NCONST class? Thanks!
If you have multiple arrays and they can exceed 64Kbytes in size (each) then you will have to change your memory type to "xhuge" basically giving you an unlimited size. But also note that this is less efficient than when using the DPP's (the "near" memory modifier uses the DPP's).
also I have found that structs (I do not know about arrays, but why should that be different?) that cross 64k boundaries are handled erroneously since the offset calculation is 16 bit based. Erik
i asked this because i am using the 98K continious array previously downloaded to flash. I access it by XVAR definition and have no problems. Does it differ from using array of 'xhuge' type?
XVAR is a macro to access xhuge data, please have a look to the Keil web site. http://www.keil.com/support/man/docs/c166/c166_xvar.htm
