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.

Hi Jon,
Yes thanks - the reply did help and confirmed that I have made a (schoolboy) error. Once I thought about this for more than 1uS I realised my mistake.
Thanks for the reply.

Can I connect 5V 74LS00 to 3.3V 74HCT74?
Thank you.
"Can I connect 5V 74LS00 to 3.3V 74HCT74?"
Can you not understand that this question is entirely irrelevent to this thread of discussion - it has nothing whatsoever to do with the topic "STRING (XDATA)"
Despite being told twice already, have you not yet realised that such question have nothing whatsoever to do with Keil products?
