![]() ![]() With the same cable and the same USB port the “normal” ESP32 works perfect. I’ve tried in Arduino IDE several options by choosing many different types of ESP32 without success. The boards have only a reset button but no EN and/or BOOT button. I tried with the usual “blink” example but I always get the same error messageĪ fatal error occurred: Failed to connect to ESP32: No serial data received.įailed uploading: uploading error: exit status 2 The problem is that I was not able to upload any program on these boards. Both of them have the pins arranged in two rows from each side of the board instead of a single row so the board is almost square and not so elongated as the “normal” ESP32 and is smaller. I just bought from two different sellers two ESP32s “mini” that seem to have the same processor (ESP32-WROOM-32 is written on one and ESP-WROOM-32 on the other) even if one of the boards when connected has both the blue and the red led on while the other has just the blue led on. I did try running the Arduino IDE as admninistrator, but got the same error. ![]() Problem occurred on two different computers.Įrror: 13 INTERNAL: Cannot install tool esp32: : moving extracted archive to destination dir: rename C:\Users\pjfit\AppData\Local\Arduino15\tmp\package-2000256404\xtensa-esp32-elf C:\Users\pjfit\AppData\Local\Arduino15\packages\esp32\tools\xtensa-esp32-elf-gcc\1.22.0-97-gc752ad5-5.2.0: Access is denied.Īt this point (after the error) C:\Users\pjfit\AppData\Local\Arduino15\tmp is empty (which seems reasonable), but the C:\Users\pjfit\AppData\Local\Arduino15\packages\esp32\tools directory is empty too (which doesn’t seem reasonable). Computer O/S is Windows 10 Home version 21H2 (build 19044.2075). I am getting an installation error on attempting to install “esp32 by Espressif Systems” (step 4 above).Īrduino IDE is 2.0.1.
