Title: Unable to upload sketch after Soft Reset
Post by: Oomek on November 01, 2016, 08:45:23 am

When I'm trying to upload sketch after calling the function from wiki it fails.

Code: [Select]

void reboot(void) {
  noInterrupts(); // disable interrupts which could mess with changing prescaler
  CLKPR = 0b10000000; // enable prescaler speed change
  CLKPR = 0; // set prescaler to default (16mhz) mode required by bootloader
  void (*ptrToFunction)(); // allocate a function pointer
  ptrToFunction = 0x0000; // set function pointer to bootloader reset vector
  (*ptrToFunction)(); // jump to reset, which bounces in to bootloader
}

What can I do to fix it?

Here is the log:

Code: [Select]

I've tried also a simpler method

Code: [Select]

void(* resetDigispark) (void) = 0;but the result is the same.
