reset_cpu() way doesn't work properly with my code
PostPosted: Wed Oct 20, 2010 8:22 am     Reply with quote
Hi,

I want to reset the chip and go into bootloader mode so I called
reset_cpu();
directly.

The bootloader is the USB HID bootloader
Code:

void main(void)
{
  if(RCONbits.POR == 1)//RCON bits POR power on reset, yes->go to bootloader, value is 0 on POR, hold is 1
   {
      RCONbits.POR = 0;
   }
   else   //This example uses the sw I/O pin to determine if the device should enter the bootloader, or the main application code
   {
      RCONbits.POR = 1;
      _asm
      goto 0x1000         //RM_RESET_VECTOR If the user is not trying to enter the bootloader, go straight to the main application remapped "reset" vector.
      _endasm
   }

    InitializeSystem();
while(1)
{
//do something
}

but it seems that the chip will just hang after invoked reset_cpu()
it works on some computers, but will hang on others
any idea?
