A little Espressif helper for programming

While developing boards, we often want to program ESP chips without going through the onboard USB port; this adapter will help us (and others) do that! It has a CP2102N USB-serial chip

with RX/TX signal LEDs and two transistors wired up to the DTR/RTS line for the 'esptool standard' reset procedure technique. The output IO, plus a 3.3V 500mA regulated output, is available on a socket header, so you can plug wires in for quick programming and debugging. You can use this for everything from an ESP8266 to an ESP32-P4!

Fehler mit esptool - TypeError: argument of type 'NoneType' is not iterable

Wie du den Fehler "TypeError: argument of type 'NoneType' is not iterable" mit dem Upload des esptool behebst, zeige ich dir in diesem neuen Beitrag. Traceback (most recent call last): File "esptool.py", line 37, in File "esptool__init__.py", line 1064, in _main File "esptool__init__.py", line 859, in main File "esptoolcmds.py", line 466, in write_flash File "esptoolutil.py", line 37, in flash_size_bytes TypeError: argument of type 'NoneType' is not iterable Failed to execute script 'esptool' du Chip is ESP32-D0WDQ6 (revision v1.1) Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None Crystal is 40MHz MAC: 08:b6:1f:9d:16:18 Uploading stub...

Mögliche Ursache des Fehlers

Der Fehler ist in meinem Fall mit dem CrowPanel 2.4" HMI aufgetreten. Dieses Gerät verfügt neben einem ESP32-D0WDQ6 auch über ein 2,4" TFT Display vom Typ ILI9341V. Wenn ich nun ein kleines Beispiel mit einer Textausgabe auf dem Display aufspielen möchte, dann wird dieses scheinbar erfolgreich ausgeführt, jedoch wird nichts angezeigt. Danach jedoch wird immer der Fehler geworfen. Wenn jetzt auf der Kommandozeile die Ausgabe "Erasing flash (this may take a while)..." erscheint, wird die Taste BOOT wieder losgelassen. esptool.py v3.0 Serial port COM12 Connecting...... Detecting chip type... ESP32 Chip is ESP32-D0WDQ6 (revision 1) Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None Crystal is 40MHz MAC: 08:b6:1f:9d:16:18 Uploading stub... Running stub...

Dann dauert es ca. 1 Minute und der Speicher sollte anschließend gelöscht sein und der nächste Upload sollte funktionieren. Nachfolgend habe ich ein kleines Programm mit der Ausgabe von "Hallo" auf dem Mikrocontroller installiert. Dieses ist recht klein, ergo dauert das Kompilieren und der Upload nicht so lange. esptool.py v4.6 Serial port COM12 Connecting.....

Die Lösung zum Fehler "'NoneType' is not iterable" mit dem esptool habe ich von der Seite https://randomnerdtutorials.com/esp32-erase-flash-memory/ entnommen. Dort gehts eigentlich nur darum wie der Speicher gelöscht wird. Jedoch bewirkt dieses zusätzlich das Fehlerhafte konfigurationen ebenso entfernt werden. Read the full article

RP2040 USB host to program ESP chips through CDC chips

Historically, we've tested and programmed our Feather ESP8266 (https://www.adafruit.com/product/2821) and ESP32 boards (https://www.adafruit.com/product/3405) from a Raspberry Pi. We'd connect over USB and run esptool.py, which works fine but has more things that can go wrong: power flickering, SD card failures, etc. It's better to fully program it with a Pico RP2040 brain board. We can do that now because TinyUSB has support for USB CDC Serial chips (https://github.com/adafruit/Adafruit_TinyUSB_Arduino/tree/master/examples/DualRole/CDC/serial_host_bridge) like the FT232, CP210x, and WCH9102! We upload the stub and test firmware, then listen on the CDC for the self-test output. It works really fast and is much easier to manage.
