Code Compiled, linked, downloaded but not running

Hi,
Simply, is someone able to answer why with instructions above the watchdog never reset ?
A piece of code which work with c8051F500 would be cool... or INIT.A51 file which work

Thx

you need to type watchdog into the search window that comes up and find the article

INIT.A51 file which work
what is an INIT.A51 file?

Erik

what is an INIT.A51 file?

You are joking, aren't you?

Perhaps not - it would explain some of your misplaced arrogance in this thread.

Time to read the C51 manual I think...

Hi,
Thx Erik for your answer but we are searching the way to reset (refresh) the watchdog during startup and init sequence (before main call).
During this sequence, writing to PCA0CPH5 doesn't work and so doesn't refresh the Watchdog ! It's a little bit strange, isn't it ?

what is an INIT.A51 file?
You are joking, aren't you?

Yes, there is an init file build by the tools (the one between statup and main), but if that is 'user modifiable' I do not know of it. Since it is built by the tools how can it be .a51

what sequence?
the issue is NOT 'refreshing' but 'disabling'

Erik

for the f12x it looks like this, you find out how to do it for your chip (hint; it is in the documents I mentioned)

STARTUP1:
; disable watchdog
           mov   SG_WDTCN,#0DEh        ; kill the puppy
           mov   SG_WDTCN,#0ADh        ; takes 2 writes

Erik,

Read and learn ...

On my system (where the base directory is "C:\Keil") a file was written BY THE INSTALLER to:

C:\Keil\C51\Lib\INIT.A51

Unless you went for a very strange custom install, it is highly likely that you have a copy in the corresponding location of your system.

I have such a file in that location but it is not part of my builds.

from the file:
; INIT.A51: This code is executed, if the application program contains
; initialized variables at file level.

it is 'house standard' here not to have "initialized variables at file level" thus I have never seen it. So, yes, Mr Sardine and Mr. Bratwurst, I asked a question and finally got an answer, is that not what the forum is for (oh, sorry, you act as if it is for ridicule, not for information)

Anyhow it will do no good to kill the puppy there, it will already have bitten

Erik

Mr. Silly Sausage and Mr. Jack Sprat,
I hate to take sides but this time I agree with Erik. Your latest arguments were abusive, non-technical and deliberately offensive. What were you trying to prove actually? Yes Erik made a couple of contentious claims in the past (I raised an eyebrow or two when he claimed to have "no bugs" at all) and I know he is not always right (who is, for god's sake) but seriously guys - keep it down to business, and down to earth!

I have such a file in that location but it is not part of my builds.

Every time you build you link with that code. I would be amazed that you didn't know this if it were not for your apparently blanket refusal to read any documentation associated with software.

it is 'house standard' here not to have "initialized variables at file level"

How strange. Why would anyone impose such a rule?

I asked a question and finally got an answer, is that not what the forum is for

Yes, it is. There is also, however, an expectation that someone who has been using these tools for as long as you might have read the manual.

Anyhow it will do no good to kill the puppy there

The intent is that you strobe the watchdog in INIT.A51, not disable it.

it will already have bitten

Will it? How long does 'the watchdog' take to time out?

If we can not refreshing the watchdog, i 'm afraid for the use of this chip...

Tamir,

It would seem that your threshold for opinionated arrogance is higher than mine.

Anyway ... I understand what you say, and will try to refrain.

I hate to take sides but this time I agree with Erik. Your latest arguments were abusive, non-technical and deliberately offensive.

First off, if you agree with Erik you will be agreeing that I treated his behaviour with ridicule. This is correct. 'Abusive' and 'offensive' are quite a different matter. I would suggest that the use of profanity would be classed as offensive, this is quite typical of Erik's behaviour on this forum. I have also noticed that you are not averse to using language that would be considered blasphemy by at least one of the major global religions.

What were you trying to prove actually? Yes Erik made a couple of contentious claims in the past

The things that irritate are his barracking arrogance, refusal to follow his own advice, refusal to read and understand what others write, inability to understand that there are alternative approaches to many problems rather than the one deemed correct by him, inability to ever follow any discussion through to its conclusion if that conclusion reveals him to be wrong and so on.

and I know he is not always right (who is, for god's sake) but seriously guys - keep it down to business, and down to earth!

I think you need to put your own house in order before you start to dictate who should say what on this forum.

I don't know if you meant it like that, but you made me laugh...if I hurt your religious feelings I apologize.

Ouch. What a punch line! Do you mean me trying to make a hit on Marleen (ops. my girl is not going to like this post hahahahaha) :-) :-) or the religious stuff?!!?!?!?

If we can not refreshing the watchdog, i 'm afraid for the use of this chip...

I'm sure you can, and INIT.A51 is one of the right places to refresh it. Unfortunately I'm not familiar with this device, and neither, it would seem, is anyone else, so I guess you're just going to have to read the datasheet carefully to establish how to do it.

The handling of this issue (sorry Mr. Sardine) commonly accepted by all SILabs users (that have commented on this issue) is to disable the watchdog in startup.a51 and then enable it at the top of main().

now:
Every time you build you link with that code

if not exist aoc.lib goto usliex
del aoc.lib
:usliex
c:\%DDIR%\c51\bin\lib51 c aoc.lib                                       >..\trash\trashbin

if "%MUSDIR%"=="0" goto lnkdir
rem linking for boot required

BOOTbit.obj, aoc.lib TO aoc.omf CODE(0x4000 - 0xFFFF) RS(256) IX >protl.log

I do???
