I'm not sure how that happened - the only change I made to code that was running but didn't produce result (it stuck somewhere but didn't lock up the board) was putting constants (offsets of S-box to pointer to BF_ctx structure) in registers. I used only caller saved registers (r16-r27 and r12), iadd instead of add and just followed C code and compiler generated assembly code and wrote BF_ROUND from scratch just to make it work. My guess is that I wasn't loading values from S-box but from somewhere else. I'm sorry and I'll be more careful with future tests. Katja Content of type "text/html" skipped
