It obviously isn't recommended, but I tested it here some months ago and it didn't make any smoke or heat. But, you can't charge at all like that. As soon as you set hostmode <- 1 then power path from USB socket to PMU is disabled (so it doesn't try charge from its own generated power). If you leave hostmode at 0, provide external power AND add 15K pulldowns on D+ and D- externally, you can have your host cake and eat your charger... er... well, have it both ways. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkiZX+cACgkQOjLpvpq7dMpDVQCeMezY3Jnty4FrFSWBe8p9OroK 2MoAnR6jGAIcHjJxsZEs2n9Rgq/TQw/k =2eB2 -----END PGP SIGNATURE----- _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
