Hello, when do you receive that error message? Which Operating System are you using? Thanks!

Sorry Rui, my question was incomplete – I had only searched for “update falsch”! I wanted to flash an ESP 01 with MiniPython.
Sara wrote to me that I should use a different version.
I will try it tonight.

Hello Roy,
even with the MiniPython version for 512 kB, programming an ESP01 does not work.
My equipment consists of:
Laptop Lenovo with Winsdows 10, latest updates, USB programmer (for Ardunio) with interface for ESP 01. Programming with Ardunio without problems.
For MiniPython I use uPyCraft IDE, V1.1:
Parameter – COM6, board – ESP8266, erase – yes
Firmware Users – esp8266-512k-20190113-c1.9.4-779-g5064df207.bin
erase flash – ok
burn (led is flashing) – after 10 … 20 sec – attention update false
What am I doing wrong?
Greetings from Dresden Roland

Hello again! I think I know what’s happening.

  • The erase flash is OK, because you’ve connected GPIO 0 to GND. Right?
  • After the erase flash, you need to keep GPIO 0 to GND and reset your board. That process needs to be very quick, but after the erase process, you need to force the ESP-01 to go into uploading mode again.

We’ve just posted a new guide using the esptool.py to flash the ESP32/ESP8266 with MicroPython. I think this new post will work better for you: https://randomnerdtutorials.com/flashing-micropython-firmware-esptool-py-esp32-esp8266/
Basically, before flashing the erase flash command and the write flash command, you need to restart your board with GPIO 0 connected to GND to ensure that it’s in flashing mode.

That process is not described in our guide, because with ESP development boards they have the built-in BOOT/FLASH button.
