Hello

I have simple program that get byte from spi channel and send it to SCI channel.

When I program/burn it to the board, then it runs fine.

when I load it with in-dart debugger and hit run, then the program gets TRAP and stop in first line of the program.

Can any body tell me why ?

(I think it is related to the interrupts vectors table, but I don't know how to fix it)

File is attached

Thanks

Oren

Correction!!!

I get traps also when it burnned into the flash.

(I made a test like this:

printout character

endlessloop

code here

jump back to endlessloop

and I got the printout characters every 250ms (estimation only)

)

why I get this traps ????

Thanks

Hi Oren,

my guess is that your problem is due to a watchdog reset. Do you take care of not programming hardware watchdog or refreshing the watchdog in order for it not to trigger a reset ?

Helo Alaini

I thought about the watchdog.

I am doing anything with the watchdog.

It stays the same way as it was in power up, and I understand that it is disabled by default.

(The entire code is attached in the main.asm, in original message)

Any more hints ?

Thanks

Oren

hello all

I got answer for this and it was right.

The problem was that the option bytes was configured to hw watchdog, meaning the WD starts automatically after the reset and reset the MCU if not refreshed within the correct time window

I saw that in the STVD debugger there is a place to change the option bytes. I changed it to SW WD and now it is ok.
