Assuming nothing is unsigned long long or bigger, it should all promote to long long. That's 63 bits at minimum, not counting the sign bit. Even if it were 31-bit, you'd have: 24 days, 20 hours, 31 minutes, 23 seconds, 647 milliseconds That's quite the marathon debug session. _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
