	Assembling file after IDA disassemble « on: January 14, 2016, 01:02:58 AM »

Hi.

Is it any chance to return assembling file directly in IDA if I've done some changes in code?
Or we must doing it by any c166 assembler?
What I look, assemblers don't have simmilar entertainment to IDA like word_xxxxxx byte_xxxxxx. Code must be definied other way.

If you incject some code into ori software of course you can dissasembly again and check your work.

But I mean if I could disasembly by IDA --> incject some changes to code also in IDA and assemble also by Ida. Is it executable?

nope
im using keil -> hex output -> import hex in hex redactor

you should use asm syntax to define variables
and dont forget about segments or pages

Code:

mov r4, 0F043h ; 0xF043

Code:

pussy EQU 0F043h
...
mov r4, pussy ; 0xF043

Code:

exts #38h, #1
mov r4, 0433h  ; 0x380433

etc
