Hi all,
I have the follow problem: after a software reset, given by:

applications seems to have some problems reinitializing. Note that I use the same startup code used at power-on reset.

I wonder how I should correctly reinitialize application after a software reset.

Thanks a lot.
bye

Hi,
try to also reset the peripherals:

Or trigger an external reset using bit AT91C_RSTC_EXTRST

Unfortunately for the application is MANDATORY to maintain the gpio state during reset. For that reason I cannot reset the peripherals and external...

The only way is to make the startup from software reset to work correctly

any other ideas?
thanks

Sorry, but you did not say that it is mandatory to maintain the gpio state.
So it was not necessary to write mandatory in large red letters!!!

Do you disable all interrupts and DMA-transfers? Did you debug your code to see where the processor hangs?

OK... sorry

We do not use DMA, and we tryed both cases: software reset whit interrupt enabled and disabled, with the same result.
It seems that after reset a generic interrupt is raised (but ISR is 0), and it loops. In this state after few seconds WDC will resets making GPIO pins to have an undesired behaviour.
It seems that debugging is invasive. The behaviour is different between debugging or not.

Do you have some other ideas?
Which is the correct procedure to restart after software reset? Is it described in details in some document?

thanks
