ESP32-U4WDH embedded flash specifications

What is the rated erase cycle for the embedded flash of the ESP32-U4WDH? 100K, 10k, less, more? I can't seem to find this info anywhere.

Yes, removing vTaskStartScheduler() solved the problem.
And to get around timer calling xHandle before it is started I put in a check to see if xHandle has been started in the timer callback.

Code: Select all

			vTaskResume(xHandle);
		}

I am using ESP32-DevKitM-1 which has a single core ESP32 SoC, ECLIPSE, ESP-IDF v 4.3. I started with the uart_events example and when I use xTimerCreate() and run vTaskStartScheduler() this is what happens: If I don't start the timer before running the scheduler = Crash assertion "xReturn != ( -1 )"...
