Hi all
I tried to define an array of 256 bytes in external ram as pdata as:

unsigned char pdata PDat[256];
main(){ }

But I am getting the following message by KEIL and RIDE Linker:

ERROR L134: SEGMENT DOES NOT FIT IN PDATA PAGE
SPACE: XDATA
SEGMENT: ?PD?T1
LENGTH: 0100 H

if I chane it to PDat[255] then there is no error.
But the Frankln's ProView compile and link it with out any error.
Can someone explain, Why?

Regards

Yep, 0 to 256 = 257 (100H) addresses. 0 to 255 = 256(0FFH) addresses.

A page is 256 bytes.

I don't know why Franklin's compiler ignores the illegal array length.
