`esptool` frequently fails when trying to open the serial port of a device which deep-sleeps often: $ esptool.py --chip esp32s3 -p /dev/cu.usbmodem6101 [...] write_flash foo.bin Serial port /dev/cu.usbmodem6101 A fatal error occurred: Could not open /dev/cu.usbmodem6101, the port is busy or doesn't exist. ([Errno 35] Could not exclusively lock port [...]: [Errno 35] Resource temporarily unavailable) This makes developers add unnecessarily long sleeps when the main CPU is awake, in order to give `esptool` the chance to find the serial port. This PR adds a new env variable `DEFAULT_OPEN_PORT_ATTEMPTS` and cfg file entry `retry_open_serial` which attempts to open the port selected number of times (optionaly indefinitely) until the device shows up: $ export DEFAULT_OPEN_PORT_ATTEMPTS=1 $ esptool.py --chip esp32s3 -p /dev/cu.usbmodem6101 [...] write_flash foo.bin Serial port /dev/cu.usbmodem6101 [Errno 35] Could not exclusively lock port [...]: [Errno 35] Resource temporarily unavailable Retrying to open port ......................... Connecting.... Chip is ESP32-S3 (QFN56) (revision v0.2) [...] Closes espressif#995
This change solves the issues when running on Windows
This commit adds test for overclock and watchdog. The tests are executed only on ESP32-C3 as there would have to be a different register value for each chip.
