Buongiorno a tutti,
di recente mi è arrivata una scheda ESP32 con un telecamera montata.
Caricando i programmi di esempio ho notato che i messaggi di errore si riferivano al fatto che il bootloader esptool non è in grado di leggere la dimensione della ROM della scheda.
Spulciando su internet ho scoperto che è necessario installare python (consigliano la versione 3.4) e attraverso i comandi "pip" installare l'esptool.
Tentanto di installare l'esptool (con il comando pip install esptool) riporto questo messaggio di errore:
C:\Users\ottov>pip install esptool
Defaulting to user installation because normal site-packages is not writeable

E' da giorni che sto cercando di risolvere ma non so dove parare.
Sarei grato se qualcuno che conosce bene python ed esp32 riuscisse a darmi una mano
