How can I fill a 4 byte data patten as "0xFE 0xCA 0xBE 0xBA" to code area from address 0x7ffc to 0x7fff.
"With a small assembler module..." IF you want to stick with 'C': 1. Create a 'C' module that defines an appropriate initialised variable in CODE space - and nothing else. 2. Use the Linker to locate the resulting segment to the required address.
