STRING (XDATA)

Andy Atkinson

Hi All,

Target : ST Micro uPSD3354V

I have a number of (implicit) strings in my application that I want to move from CODE space to XADATA as I am approaching the 64KB threshold, and I do not want to move to code banking.

So I tried using STRING (XDATA) to force my implicit strings into XDATA rather than CODE. Everything compiled and linked no problems, but my application now does nothing! If I change nothing except remove the compile option STRING (XDATA) all is well once more.

With STRING (XDATA) in place I try and launch my debugger only to be told that the loaded app does not match what's in ROM and so I cannot debug the problem (at the moment).

Does anyone have any pearls of wisdom they wish to pass on regarding this scenario? Is there some deeper issue I am missing regarding the use of STRING (XDATA)? Is there an alternative strategy for getting my implicit strings out of CODE and into XDATA?

Any help appreciated.

Andy Atkinson
