[RESOLU] IDE 1.0.2 & Leonardo : le port COM disparait

International Français
4

Je n'ai aucun autre port virtuel, en tout cas actif (aucun autre port COM)

Voici ce qui se passe si je fait un upload depuis l'IDE 1.0.2 :

Binary sketch size: 5 588 bytes (of a 28 672 byte maximum)
Forcing reset using 1200bps open/close on port COM3
PORTS {COM3, } / {COM3, } => {}
PORTS {COM3, } / {COM3, } => {}
PORTS {COM3, } / {COM3, } => {}
PORTS {COM3, } / {COM3, } => {}
PORTS {COM3, } / {COM3, } => {}
PORTS {COM3, } / {COM3, } => {}
PORTS {COM3, } / {COM3, } => {}
PORTS {COM3, } / {COM3, } => {}
PORTS {COM3, } / {} => {}
PORTS {} / {} => {}
PORTS {} / {COM3, } => {COM3, }
Found Leonardo upload port: COM3

avrdude done. Thank you.

Et là, plus de port COM3 (mes 2 ports COM bootloader et série sont réglés sur COM3)

Si j'utilise l'IDE 1.0.1, l'upload s’arrête à "avrdude done. Thank you." et les ports COM partent et reviennent normalement .

De ton coté, tu vois bien passer cette phase de reconfiguration du port COM et ca se passe bien ?
