Hello,
I am trying to use a Chinese
"ESP32-DevKitC V4 board, WROOM-32D "
( https://www.aliexpress.com/item/4000103411061.html ), using a
64 bits laptop win 10 version 1903,
and have the
Arduino 1.8.13
installed along with the specification for the link to the ESP32 github
This board name does not appear as such in the ESP32 list of boards on the Arduino GUI.
I have tried the "ESP32 Dev Module", and tried also "FireBeetle ESP32" (after some hints found while googling for Arduino WROOM-32D)
When I try to upload the "blink" example, I get as message once compiling is done (selection FireBeetle ESP32 board):
"C:\Users\Administrateur\AppData\Local\Arduino15\packages\esp32\tools\xtensa-esp32-elf-gcc\1.22.0-80-g6c4433a-5.2.0/bin/xtensa-esp32-elf-size" -A "C:\Users\ADMINI~1\AppData\Local\Temp\arduino_build_172699/Blink.ino.elf"
Le croquis utilise 207705 octets (15%) de l'espace de stockage de programmes. Le maximum est de 1310720 octets.
Les variables globales utilisent 15228 octets (4%) de mémoire dynamique, ce qui laisse 312452 octets pour les variables locales. Le maximum est de 327680 octets.

From the message, the on-board chip seem to have been identified (ESP32D0WDQ6), along with a Mac address
But it's not blinking 
!
Is it a bad board selection I did or yet something else ?
Help !
note1: when I try to get the card's info with the Arduino GUI, I get:
BN: Carte inconnue
VID: 10C4
PID: EA60
SN: Envoyez un croquis pour l'obtenir
note2:
When the board is plugged into USB on my Laptop, the Com port on windows appears as "Silicon Labs CP210X USB to UART Bridge (COM3), pilot version 10.1.9.2677 (dated 28/07/2020).
In the "Event" tab I get:
"L'appareil USB\VID_10C4&PID_EA60\0001 n’a pas été migré à cause d'une correspondance partielle ou ambiguë.
Dernier ID d'instance d'appareil : USB\VID_0B95&PID_772B\0001D0
GUID de classe : {4d36e972-e325-11ce-bfc1-08002be10318}
Chemin d'accès d'emplacement : PCIROOT(0)#PCI(1400)#USBROOT(0)#USB(2)
Rang de la migration : 0xF000FFFFE0000023

I tried to un-install/reinstall the driver, but I get the same migration error.
I do not know whether this migration error induces the no-blinking problem encountered.
