Well, powering up on insertion would certainly solve the problems of charger indication (if we booted) and charging (if even U-Boot gets to run) alright.

Finally something works as expected ;-) You're saying that you don't think we can ever bring the CPU up at all if you have a battery in there that is < 2.5V? No matter what buttons you're pressing? Or just auto start from USB insertion is then broken? ~ Or all of this only happens if we disable charging from the previous session? - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEUEARECAAYFAkhevCkACgkQOjLpvpq7dMonLwCYu7bCwj35vXS8yRw5iq9WvOuA ZACfWJ3yo/vFntl2cDIrO/qkom0A+Pk= =n+Mt -----END PGP SIGNATURE-----
