Hi, Do you have faced with this problem ? The USB debug adapter runs but the IDE debugger not. I can put breakpoint on the first line of the main but no break, no timer it generated too, when i stop running no stop on the code line executing. It seems there is a problem just before the main call.
thx
Hi, Thx for your quick responses, indeed it seems to be the watchdog, before main call, which reset. But do you know how what to write in the WATCHDOG macro in INIT.A51 file ?
here is my current watchdog reset macro. but seem to not work. however LST file show the macro at right place.
User-defined Watch-Dog Refresh. ; ; If the C application contains many initialized variables uses a watchdog ; it might be possible that the user has to include a watchdog refresh into ; the initialization process. The watchdog refresh routine can be included ; in the following MACRO and can alter all CPU registers except ; DPTR. ; WATCHDOG MACRO MOV 0CFH,#78H ENDM
mister orange,
have you disabelled the macro's in the ide?
thanx
hi, i'm using the silabs IDE with Keil compiler. so there is no macro options.
here part of LST file.. 003B 156 ?C_START: 003B 900000 F 157 MOV DPTR,#?C_INITSEG 003E 158 Loop: 159 WATCHDOG 003E 75CF78 160+1 MOV 0CFH,#78H 0041 E4 161 CLR A
i mean it's the watchdog reset method that not working..
it is 100 times easier to see what it is if you do not show code using macros BTW why are you even using a macro for something you only do once?
Erik
Hi, See Cx51.chm, "searching" with keyword: "watchdog" and you will see why ?
Thx
CX51 has no idea in the world how a SILabs watchdog works.
WHY do you REFUSE to do what i suggest?
THE END
It is fortunate that in a free society people have choices!
Some choices are better than others...
WHY do you REFUSE to read what he writes?
What a relief!
Erik,
in this project, we must use standard startup files from compiler. (mandatory for our customer) If Keil define one Macro to refresh WDT... why modify directly the code ? this method of work is better for futur upgrade of startup files. we don't have to modify the code.
i can try your idea but i don't see what is different than by macro.. macro principle is to replace keyword by some instructions. Macro is generaly defined in top of file to easily identify changeable portion of code.
but i'll try your suggestion now.
It would be if it were true. But just wait ... He'll be back with his usual 'style'!
?C_START: MOV DPTR,#?C_INITSEG Loop: MOV 0CFH,#0H ; WATCHDOG CLR A
in this project, we must use standard startup files from compiler. (mandatory for our customer) then tell you customer "we can't" and show him the silabs knowledge base articles

so, is THAT enough to get you to do what you need to do instead of trying to do something else that you 'prefer' but does does not work
in the preview I see both links are the same you need to type watchdog into the search window that comes up and find the two articles.
PS to the sardine: if you would takr the time to verify that I was wrong (which I am not) before you spewed your bile, there woould be a whole lot less of it

Where did I say you were wrong?
The poor chap is merely trying to explain why he's doing what he's doing (following the instructions in the documentation) yet you just keep yelling at him before finally flying into a sulk and saying you're not playing any more. Sadly your sulks don't seem to last very long.
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
