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, C8051F50XDK, Silicon Labs USB Debug Adpater, Keil A51, C51, BL51, Silicon Labs IDE.

do0 you disable the watchdog INMMEDIATELY after startup:
Hi, i don't think about the watchdog because i even never arrive at the first instruction in the main. what do you think about the watchdog ?
i even never arrive at the first instruction in the main that is ECACTLY what happens when you do not disable the watchdog.
I have to disable the watchdog in the IDE or in the code ?
I think you have a very serious problem and it requires careful analysis.
Post all the code here and we will check it for you.
I think you have a very serious problem and it requires careful analysis. yes, he does: I have to disable the watchdog in the IDE or in the code ? but no "careful analysis" needed
What on earth does the ide have to do with the watchdogs operation???
the watchdog must be disabled AT THE START OF startup.a51
Post the code.
Erik will then spend some time looking at it and he will advise you as to what must be modified.
I don't really understand all requests for code in this and other threads. Is it in the hope that the posted code - after correction - will be possible to turn in as a school assignment?
already done
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?
