SimulIDE / Discussion / Bugs, Errors and Other Problems: Crashing when run a simulation with an atmega1280,1281,1284,2560

Anonymous - 2018-08-24

when i run a simulation with atmega 1280,1281,1284,2560 the simulation crashes

with all other devices the simulation works

asm code :

start:
sbi ddrb,0

loop:
sbi portb,0
ldi r16,255
zur:
dec r16
brne zur
cbi portb,0
ldi r16,255
zur1:
dec r16
brne zur1
rjmp loop

Yes, somehow wrong files got in the release.

In folder:
SimulIDE_0.2.8/share/simulide/data/avr/

These files are wrong:
atmega1280.data
atmega1281.data
atmega1284.data
atmega2560.data

Attached to this post are correct files.

Thanks for reporting!

Hi Ronomir.

I can't reproduce the issue.
Could you provide files you used?

  What files are needed?

  I collect a test pattern using attiny2313. After downloading the firmware when the simulation starts, the program sometimes crashes.

Circuit file and firmware file.
Anything i can use to reproduce the issue.

  I send files. The project is just beginning to be developed, new elements will be added. The program terminates abnormally when the simulation starts. This does not always happen, but often.
  
  test-1.simu
  
  test.hex

I can not make it crash, but if i start, stop, start again, simulide gui gets blocked.

What language/compiler are you using to generate hex file?

  I used the compiler CodeVisionAVR Evaluation

  Now I checked the simulation of the project again. The simulation is performed normally for the first time. When the simulation is re-enabled, after a few seconds the program freezes and then crashes.

Ok, i found the problem.
This issue will be solved in next release.

The only workaround i can think is clearing the attiny General Purpose Working Registers just at the benining of the program.
But i don't think your compiler lets you clear the attiny General Purpose Working Registers...

I did a modified version of test.hex that should work, just to test the workaround.

Thanks for testing and reporting, this issue was really hidden and you provided the perfect case to catch it.

test3.hex

  Thanks for a quick fix! Now everything works correctly. Was glad to help. Thank you for making this program. I've been looking for something like that for a long time!

Btw.. are you using Linux or Windows?

  I'm using Windows.

Try this simulide build with the issue solved:
https://sourceforge.net/projects/simulide/files/SimulIDE_0.2.8/Test/SimulIDE_0.2.8-Test-Win32.zip/download

Your project should simulate ok with this one.

        Testing this version and confirming it works properly is already a good help.
        I'm not sure that the solution didn't break something else...
        
        If you add more stuff to your project and find simulide is not simulating properly you can report here.

        I plan more projects with this program. If errors are found, I will inform you.

        I want to suggest the possibility to expose fuses in microcontrollers AVR.

        I will have a look to see how to expose fuses, but i'm not sure...
        I have to think about it.
