===== 1er pas, 1ers problèmes =====

==== Error updateLastError() for com.sun.jna.Native ====

En exécutant la commande
  $ ./ioiodude --port=/dev/IOIO0 versions
j'obtiens cette erreur :
  Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't obtain updateLastError method for class com.sun.jna.Native
	at com.sun.jna.Native.initIDs(Native Method)
	at com.sun.jna.Native.<clinit>(Native.java:139)

	at ioio.dude.IOIODudeMain.main(Unknown Source)
La solution que j'ai trouvé, sur la liste [[https://groups.google.com/forum/#!forum/ioio-users|ioio-users]] c'est de désinstaller la bibliothèque "libjna-java":
  sudo apt-get autoremove libjna-java

==== Mettre à jour le firmware de la IOIO-OTG ====

D'origine j'ai:
  $ ./ioiodude --port=/dev/IOIO0 versions
  IOIO Bootloader detected.
  
  Hardware version: SPRK0020
  Bootloader version: IOIO0400
  Platform version: IOIO0030

Programmation du firmware App-IOIO0500:
  $ ./ioiodude --port=/dev/IOIO0 --reset write App-IOIO0500.ioioapp 
  Comparing fingerprints...
  Fingerprint mismatch.
  Writing image...
  [########################################]
  Writing fingerprint...
  Done.

Et voilà la version 5 installée:
  $ ./ioiodude --port=/dev/IOIO0 versions
  IOIO Application detected.
  
  Hardware version: SPRK0020
  Bootloader version: IOIO0400
  Application version: IOIO0500
