1 open project HELLO 2 insert int e,b,c; after main 3 in project devce select extended linker 4 translate 5 debug and see that variable e ????? what is it? is it new version?
special for you e=0; /*------------------------------------------------ Note that an embedded program never exits (because there is no operating system to return to). It must loop and execute forever. ------------------------------------------------*/ while (1) { P1 ^= 0x01; /* Toggle P1.0 each time we print */ printf ("Hello World %i \n",e); /* Print "Hello World" */ e=e+10; P0 =e; }
Yes! It's true. I just now repeat this experiment and see: if I select extended linker LX51 then I don't see value of variable 'e', ever I use this variable in my program. When I change C51 Optimizing Level to 7 (Extended Index Access Optimizing) - voila! I see variable in debugger! Great! But if optimizing level more than 7 or Emphasis no 'Favor Speed' or I check box 'Linker Code Packing' - this bug return. What is it?
"But if optimizing level more than 7 or Emphasis no 'Favor Speed' or I check box 'Linker Code Packing' - this bug return." Have you actually tried reading any of the answers to your original post? You have just demonstrated in agreement with those answers that you are NOT seeing a bug - you are seeing expected behaviour.

main() { int e; while(1) { e++; } }
Well I'm sorry, but I read "ever I use this variable in my program" as "never I use this variable in my program". It works fine on v7.01. Stefan
few words about magic select EXTENDED LINKER all began in 702 - if you have no this select the longest linear program didnt translate - in 704 ver is ok - but variable dont show- in 705 ok - and now 706 repeat all bugs - I think is programm eror which swimming in progam - and dificult for programmer which dont work whith IDE
I think is programm =I think It is ....
This problem has been corrected. Refer to the following knowledgebase for the fix: http://www.keil.com/support/docs/2592.htm Jon
3 days discussion - it isnot ;-) and fix bug ;-)
wow - remove one bug but add two soft bugs ;-( after patch I see FIRST When i switch number base from HEX to DECIMAL for variable e i see ok but if execute printf ("Hello World %i \n",e); after it number base switch again to HEX - it isnt good Second problem only soft problem when i translate program and switch to debug first time all ok after it switch to translate and switch to debug again i see what function debug not active but if i go to function(step and so on) debug mouse - function will be select and active and all work ok but again it isnt good
