#55733 - Atmel 89C55WD cannot read with MOVC
Hi,

with the following variable declaration, I declare a char string and initialize it to "abc".
xdata char msg1[]="abc";

I use 8952 and Atmel 8955WD with my target system. Everthing is OK when I use 8952; however with 89C55WD initialization of the variable fails and I only find empty string with this variable.

I also encounter similar problem when I use pointers to code space: I read 0x00 from that location (even it is not 0x00)

As I already mentioned, there is no problem with 8952; but with 89C55WD I think that I cannot read with MOVC.

Can anyone have any clue about this behavior of Atmel 89C55WD?
